What do plants need
Plants need four things to live: water, nutrients, light, and soil. Water is absorbed by roots and transported throughout the plant. Nutrients are absorbed from the soil through roots. Leaves use light energy and carbon dioxide to produce food through photosynthesis. Soil provides anchoring and a source of water and nutrients for roots.
Plants
This document discusses the importance of plants and their basic biology. It explains that plants are essential to human life by providing food, medicine, clothing and oxygen. Plants perform photosynthesis to produce their own food from sunlight, water and carbon dioxide. The key parts of plants - roots, stems, leaves, flowers and seeds - are described along with their functions. Plants need soil, water, sunlight and air to grow. The document also provides some fun facts about different plants.

The document discusses the various steps involved in crop production, including preparing the soil, selecting and sowing seeds, providing manure and irrigation, weeding, harvesting, threshing, winnowing, and storage. The key steps are:
1) Preparing the soil through turning and loosening.
2) Selecting high quality seeds and sowing them at the proper depth and distance.
3) Providing manure and fertilizers to the soil and irrigating the crops using methods like sprinklers or drip irrigation.
4) Removing unwanted weeds that compete with crops for resources.
5) Harvesting mature crops, separating grains from plants through threshing, and removing chaff from grains through

Plants are able to produce their own food through the process of photosynthesis. Photosynthesis requires light from the sun, carbon dioxide from the air, and water from the plant's roots. Most plants reproduce by making seeds, which first requires the plant to get pollen from a similar plant. Pollen can be transferred by wind or by animals like bees. Seeds contain a baby plant and food to help it grow. Plants must adapt to their environment through adaptations like leaves, roots, and other structures in order to survive.
Plants Exam Review
Plants are living things that are born from seeds or spores, make their own food through photosynthesis, and can reproduce. They differ from animals in that plants make their own food rather than eating other organisms, cannot move, and are born from seeds rather than eggs. The main parts of a plant include roots that absorb water and minerals, a stem that transports fluids and holds leaves and branches, and leaves that perform photosynthesis. Plants can be classified by their stem as trees, bushes, or grasses, or by their uses as ornamental, nutritious, aromatic, or weeds.

The document discusses plants and their basic needs for growth, including water, air, sunlight, and nutrients from soil. It asks questions about what plants need to live and grow, such as water, air, or both water and air. It also asks where plants get nutrients, from soil, air, or sunlight. The document discusses the conditions plants need to grow, such as a dry place, dark room, or light, moist room. It lists some important things plants need for natural growth, such as sufficient space, water, air, and sunlight.
Plant needs
Plants need sunlight, water, temperature regulation, nutrients from soil, space to grow both above and below ground, and fresh air and healthy soil to survive. Without these key requirements, plants will become stressed, stunted, and ultimately die. The document outlines the specific needs of plants for sunlight, water, temperature regulation, nutrients, space, air, and soil.

Plants need water, light, nutrients, and warmth to grow properly. Water is necessary for seed germination and plant growth. Plants use sunlight to produce their own food through photosynthesis. Nutrients from the soil provide minerals for healthy growth. Temperatures that are too cold or too hot can affect how well a plant thrives.
Plants
Plants are living organisms that obtain energy from sunlight via photosynthesis. They produce their own food and provide essential resources like oxygen, food, wood, and shelter to animals. Plants come in many forms including terrestrial plants like trees and annuals, and aquatic plants like algae. Some plants have unusual adaptations for survival like cacti that store water or carnivorous plants that trap insects for nutrients. Plants and animals depend on each other as animals provide carbon dioxide for photosynthesis and nutrients to soil when they die.

The document discusses the different parts of a plant and their uses. It describes the root, which grows underground and takes in water and minerals, and the shoot, which includes the stem, leaves, flowers and fruits above ground. It then provides details on the uses of each part, including that leaves perform photosynthesis to make food, stems transport water and food, roots provide support and absorb water, and flowers help with reproduction by forming fruits containing seeds.
Parts of plants
The document discusses the parts of a plant and how plants grow from seeds. It notes that roots take in water and nutrients from the soil, stems hold up the plant and move water and nutrients, and leaves use sunlight, air, water and nutrients to make food. Flowers make fruits containing seeds. Seeds are scattered by planting, animals, water and wind and can germinate into seedlings when they have sunlight, air, water and nutrients.
Plants, Roots and stem
1) The document discusses the different parts of plants including leaves, flowers, fruits, stems, and roots.
2) It describes how stems carry water and nutrients throughout the plant to support its growth, and how roots absorb water and minerals from the soil to sustain the plant.
3) The document outlines two main types of roots: tap roots which have one main root and smaller roots branching off, and fibrous roots which have many similarly-sized roots spreading out.

Introduction to Plants and Plant Science (The DIRT Society)
1. Plants have highly complex biological systems that allow them to photosynthesize, reproduce sexually, communicate, and adapt to their environments through various means such as changing leaf shape or dropping leaves seasonally.
2. Despite humanity's technological achievements, plants evolve and adapt more quickly and efficiently than humans are able to.
3. Plants are essentially self-sufficient from a very early stage, needing only sunlight, water and nutrients to grow, while human infants require extensive external support to survive and develop into adults.
PLANT KINGDOM -NON FLOWERING PLANT & CRYPTOGRAM.pdf
Nonflowering plants such as ferns and mosses reproduce using spores instead of seeds. Ferns do not like direct sunlight and reproduce via spores. Mosses prefer damp, shady areas and also reproduce using spores. Cryptograms are any plant that reproduces using spores, including ferns and mosses. They do not produce flowers, seeds or fruits. Examples of cryptograms discussed are algae, mushrooms and fungi. Algae are classified as non-flowering plants, consisting of strands or cells, relying on photosynthesis and being commonly found in wet areas.

Quantitative genetics – study of inheritance of quantitative characters or polygenic characters in experimental populations.
Discovery of Merging Twin Quasars at z=6.05
We report the discovery of two quasars at a redshift of z = 6.05 in the process of merging. They were
serendipitously discovered from the deep multiband imaging data collected by the Hyper Suprime-Cam (HSC)
Subaru Strategic Program survey. The quasars, HSC J121503.42−014858.7 (C1) and HSC J121503.55−014859.3
(C2), both have luminous (>1043 erg s−1
) Lyα emission with a clear broad component (full width at half
maximum >1000 km s−1
). The rest-frame ultraviolet (UV) absolute magnitudes are M1450 = − 23.106 ± 0.017
(C1) and −22.662 ± 0.024 (C2). Our crude estimates of the black hole masses provide log 8.1 0. ( ) M M BH = 3
in both sources. The two quasars are separated by 12 kpc in projected proper distance, bridged by a structure in the
rest-UV light suggesting that they are undergoing a merger. This pair is one of the most distant merging quasars
reported to date, providing crucial insight into galaxy and black hole build-up in the hierarchical structure
formation scenario. A companion paper will present the gas and dust properties captured by Atacama Large
Millimeter/submillimeter Array observations, which provide additional evidence for and detailed measurements of
the merger, and also demonstrate that the two sources are not gravitationally lensed images of a single quasar.

The growth of supermassive black holes is strongly linked to their galaxies. It has been shown that the population
mean black hole accretion rate (BHAR) primarily correlates with the galaxy stellar mass (Må) and redshift for the
general galaxy population. This work aims to provide the best measurements of BHAR as a function of Må and
redshift over ranges of 109.5 < Må < 1012 Me and z < 4. We compile an unprecedentedly large sample with 8000
active galactic nuclei (AGNs) and 1.3 million normal galaxies from nine high-quality survey fields following a
wedding cake design. We further develop a semiparametric Bayesian method that can reasonably estimate BHAR
and the corresponding uncertainties, even for sparsely populated regions in the parameter space. BHAR is
constrained by X-ray surveys sampling the AGN accretion power and UV-to-infrared multiwavelength surveys
sampling the galaxy population. Our results can independently predict the X-ray luminosity function (XLF) from
the galaxy stellar mass function (SMF), and the prediction is consistent with the observed XLF. We also try adding
external constraints from the observed SMF and XLF. We further measure BHAR for star-forming and quiescent
galaxies and show that star-forming BHAR is generally larger than or at least comparable to the quiescent BHAR.

Mechanics:- Simple and Compound Pendulum
a compound pendulum is a physical system with a more complex structure than a simple pendulum, incorporating its mass distribution and dimensions into its oscillatory motion around a fixed axis. Understanding its dynamics involves principles of rotational mechanics and the interplay between gravitational potential energy and kinetic energy. Compound pendulums are used in various scientific and engineering applications, such as seismology for measuring earthquakes, in clocks to maintain accurate timekeeping, and in mechanical systems to study oscillatory motion dynamics.

The Limited Role of the Streaming Instability during Moon and Exomoon Formation
It is generally accepted that the Moon accreted from the disk formed by an impact between the proto-Earth and
impactor, but its details are highly debated. Some models suggest that a Mars-sized impactor formed a silicate
melt-rich (vapor-poor) disk around Earth, whereas other models suggest that a highly energetic impact produced a
silicate vapor-rich disk. Such a vapor-rich disk, however, may not be suitable for the Moon formation, because
moonlets, building blocks of the Moon, of 100 m–100 km in radius may experience strong gas drag and fall onto
Earth on a short timescale, failing to grow further. This problem may be avoided if large moonlets (?100 km)
form very quickly by streaming instability, which is a process to concentrate particles enough to cause gravitational
collapse and rapid formation of planetesimals or moonlets. Here, we investigate the effect of the streaming
instability in the Moon-forming disk for the first time and find that this instability can quickly form ∼100 km-sized
moonlets. However, these moonlets are not large enough to avoid strong drag, and they still fall onto Earth quickly.
This suggests that the vapor-rich disks may not form the large Moon, and therefore the models that produce vaporpoor disks are supported. This result is applicable to general impact-induced moon-forming disks, supporting the
previous suggestion that small planets (<1.6 R⊕) are good candidates to host large moons because their impactinduced disks would likely be vapor-poor. We find a limited role of streaming instability in satellite formation in an
impact-induced disk, whereas it plays a key role during planet formation.
