Plant Organs
    Organs: tissues that act together
    to serve a specific function.

Plant Organs
Plant Organs
      – Organs composed of
        one or more tissues.
      – Three major types:
          • Roots
          • Stems
          • leaves

       – Flowers and fruits
         evolved from stems and
         leaves
Function of Plant Organs

            LEAVES – Function
               Photosynthesis

            STEMS –Function
               Suppor
               Transport.

            ROOTS – Function
               Anchorage
               Absorption
               Storage
               Conduction
ROOT

 ROOTS “the hidden half”
 Functions of roots:
   Anchorage
   Absorption of water & dissolved
    minerals
   Storage (surplus sugars, starch)
   Conduction water/nutrients
Structure of Roots
Longitudinal section of roots
   Root cap
      Zone of cell division
      Zone of cell elongation
      Zone of maturation

Cross section of root
   Vascular bundle (Stele)
     contains xylem and phloem
   Cortex
   Epidermis
   Root hairs
      Absorb water and minerals
Types of Roots
– Fibrous, multibranched roots (e.g. lettuce)
– Dominant tap root
  • Tap roots used to absorb water deep in soil
  • Some tap roots used to store carbohydrates (e.g. carrots)

– Adventitious roots
  • root-like structures arising from stems or leaves
  • e.g. prop roots (corn) and holdfasts

– Tuberous roots
  • Swollen structure on fibrous root used to store
    carbohydrates (e.g. sweet potato)
Types of Roots
  Fibrous roots        Tap root




Adventitious roots    Tuberous roots
STEMS
  Above-ground organs.
   (usually)

  Support leaves and fruits.

  Conduct water and sugars
   throughout plant.
STEM STRUCTURES
 Stem Structure
   Nodes: location of leaves on stem
   Internodes: stem between leaves
   Buds: undeveloped leaves or flowers
     – Terminal (apical)
     – axillary (lateral)
     – Apical dominance is growth inhibition caused by
       apical bud
Plant Organs
Function of Stems
 Support leaves, flowers, fruits.
 Transport of water (xylem) and products of
  photosynthesis (phloem).
 Storage of carbohydrates
    Tubers - swollen underground stems that store
     carbohydrates (e.g. potato).
    Corm - swollen base of stem covered in papery leaves.
    Bulb - cluster of fleshy leaves attached to short, thick
     stem with basal roots (e.g. onion).
    Bulbils - tiny bulbs arising in leaf axils.
    Rhizome - horizontal stem below ground that
     produces roots and shoots at each node.
Stems
 Stems used only for asexual reproduction.
 Stolon (or runner) - horizontal stem that arises from
  leaf axel and runs above ground (e.g. spider plant)
     When tip of solon hits ground a new plant forms
Types of Stems
Types of modified stems
    Spur - stem with short internodes growing from a larger
     branch of woody plant.
    Waterspout - stem that arises from latent buds in
     branches of woody plants.
    Sucker - stem arising from root tissue, often from cut
     woody plant.
Types of Stems
Types of modified stems
    Tendrils - twining stems used to secure climbing plants
     to vertical surfaces (e.g. peas, grapes).
    Prickles - tiny, pointed projections of epidermis tissues
     of stems (e.g. blackberry).
    Thorns - long, pointed projections produced in leaf axils
     (e.g. Hawthorn).
    Cladophylls - stems modified for photosynthesis
     (e.g. cacti, asparagus).
Types of modified stems
Types of modified stems
LEAVES
 Most leaves are thin and flat
   An adaptation that helps them capture sunlight for
    photosynthesis.
   Although this structure may be typical, it is certainly not
    universal.
   Leaves are extremely variable.
   This variability represents adaptations to environmental
    conditions.
Leaves structure
Leaf parts
  Blade - Flat
   expanded area
  Petiole - stalk that
   connects leaf
   blade to stem, and
   transports
   materials
  Pair of stipules
Leaf epidermis
 Is transparent – so that sun light can go through.
 Waxy cuticle protects against drying out
 Lower epidermis: stomata with guard cells – for gas
  exchange (CO2, H2O in; O2 out)


                                   A.   Cuticle
                                   B.   Upper epidermis
                                   C.   Palisade layer
                                   D.   Spongy Layer
                                   E.   Lower epidermis
Leaves functions
Leaves
  Carry out photosynthesis in order to make glucose.

  Composed of epidermal, vascular and ground tissue.
Flower
 A flower is the reproductive organ of angiosperms.
 Flowering plants reproduce by pollination.
Flower To Fruit
Fruits
  A fruit is defined as a ripened ovary that contains
   angiosperm seeds.
  The function of a fruit is to hold and protect the seeds.




 Each kernel of corn on a cob is actually an
  individual fruit
 In peaches, the fruits are soft and fleshy and
  contain a single, stony seed.
 Legumes like beans and peas produce a fruit called
  a pod that contains many seeds.

Plant Organs

  • 1. By iTutor.com T- 1-855-694-8886 Email- info@iTutor.com
  • 2. Plant Organs Organs: tissues that act together to serve a specific function. Dermal Vascular Leaves Ground Dermal Vascular Stems Ground Dermal Vascular Roots Ground
  • 4. Plant Organs – Organs composed of one or more tissues. – Three major types: • Roots • Stems • leaves – Flowers and fruits evolved from stems and leaves
  • 5. Function of Plant Organs LEAVES – Function  Photosynthesis STEMS –Function  Suppor  Transport. ROOTS – Function  Anchorage  Absorption  Storage  Conduction
  • 6. ROOT  ROOTS “the hidden half”  Functions of roots:  Anchorage  Absorption of water & dissolved minerals  Storage (surplus sugars, starch)  Conduction water/nutrients
  • 7. Structure of Roots Longitudinal section of roots  Root cap  Zone of cell division  Zone of cell elongation  Zone of maturation Cross section of root  Vascular bundle (Stele) contains xylem and phloem  Cortex  Epidermis  Root hairs  Absorb water and minerals
  • 8. Types of Roots – Fibrous, multibranched roots (e.g. lettuce) – Dominant tap root • Tap roots used to absorb water deep in soil • Some tap roots used to store carbohydrates (e.g. carrots) – Adventitious roots • root-like structures arising from stems or leaves • e.g. prop roots (corn) and holdfasts – Tuberous roots • Swollen structure on fibrous root used to store carbohydrates (e.g. sweet potato)
  • 9. Types of Roots Fibrous roots Tap root Adventitious roots Tuberous roots
  • 10. STEMS  Above-ground organs. (usually)  Support leaves and fruits.  Conduct water and sugars throughout plant.
  • 11. STEM STRUCTURES  Stem Structure  Nodes: location of leaves on stem  Internodes: stem between leaves  Buds: undeveloped leaves or flowers – Terminal (apical) – axillary (lateral) – Apical dominance is growth inhibition caused by apical bud
  • 13. Function of Stems  Support leaves, flowers, fruits.  Transport of water (xylem) and products of photosynthesis (phloem).  Storage of carbohydrates  Tubers - swollen underground stems that store carbohydrates (e.g. potato).  Corm - swollen base of stem covered in papery leaves.  Bulb - cluster of fleshy leaves attached to short, thick stem with basal roots (e.g. onion).  Bulbils - tiny bulbs arising in leaf axils.  Rhizome - horizontal stem below ground that produces roots and shoots at each node.
  • 14. Stems  Stems used only for asexual reproduction.  Stolon (or runner) - horizontal stem that arises from leaf axel and runs above ground (e.g. spider plant)  When tip of solon hits ground a new plant forms
  • 15. Types of Stems Types of modified stems  Spur - stem with short internodes growing from a larger branch of woody plant.  Waterspout - stem that arises from latent buds in branches of woody plants.  Sucker - stem arising from root tissue, often from cut woody plant.
  • 16. Types of Stems Types of modified stems  Tendrils - twining stems used to secure climbing plants to vertical surfaces (e.g. peas, grapes).  Prickles - tiny, pointed projections of epidermis tissues of stems (e.g. blackberry).  Thorns - long, pointed projections produced in leaf axils (e.g. Hawthorn).  Cladophylls - stems modified for photosynthesis (e.g. cacti, asparagus).
  • 19. LEAVES  Most leaves are thin and flat  An adaptation that helps them capture sunlight for photosynthesis.  Although this structure may be typical, it is certainly not universal.  Leaves are extremely variable.  This variability represents adaptations to environmental conditions.
  • 20. Leaves structure Leaf parts  Blade - Flat expanded area  Petiole - stalk that connects leaf blade to stem, and transports materials  Pair of stipules
  • 21. Leaf epidermis  Is transparent – so that sun light can go through.  Waxy cuticle protects against drying out  Lower epidermis: stomata with guard cells – for gas exchange (CO2, H2O in; O2 out) A. Cuticle B. Upper epidermis C. Palisade layer D. Spongy Layer E. Lower epidermis
  • 22. Leaves functions Leaves  Carry out photosynthesis in order to make glucose.  Composed of epidermal, vascular and ground tissue.
  • 23. Flower  A flower is the reproductive organ of angiosperms.  Flowering plants reproduce by pollination.
  • 25. Fruits  A fruit is defined as a ripened ovary that contains angiosperm seeds.  The function of a fruit is to hold and protect the seeds.  Each kernel of corn on a cob is actually an individual fruit  In peaches, the fruits are soft and fleshy and contain a single, stony seed.  Legumes like beans and peas produce a fruit called a pod that contains many seeds.
