Plant parts

Plant Parts

Chapter #3


What are the parts of a plant

What are the parts of a plant?

Node: swollen part of stem where buds form (leaves or stems grow here)

Cotyledons: leaves formed at first node (cotyledonary node)


What are the parts of a plant1

What are the parts of a plant?

Epicotyl: all of plant formed above cotyledonary node

Internode: stem tissue between nodes


What are the types of stems

What are the types of stems?

1) Woody Stem: trees, shrubs, woody perennials

2) Grass Stem: hollow or filled

3) Herbaceous Stem: like woody but softer (clover, alfalfa)

4) Modified Stem:


Types of modified stems

Types of Modified Stems

  • Bulbs: (onion)

  • Tubers: (potato)

  • Stolons: above ground runner (strawberry)

  • Rhizomes: below ground runners (field bindweed or creeping jenny)


What are the functions of stems

What are the functions of stems?

1) transport water, nutrients, sugars

2) support leaves

3) store food


What are buds

What are buds?

  • special tissue on stems that can grow into new plant parts

  • buds are described according to:


Plant parts

  • 1) structures into which they grow

    • -Vegetative: leaves or stems

    • -Floral: flowers

    • -Mixed: both

  • 2) where buds appear on stem

    • -Apical: tips of stems

      • -if floral = bush

      • -if vegetative = vine

    • -Axillary: where leaf joins stem

    • -Adventitious: near wounds

  • 3) How buds are arranged


Bud arrangements

Bud Arrangements

  • Alternate (alfalfa)

  • Opposite (beans)

  • Whorled (not common)


What is apical dominance

What is Apical Dominance?

  • apical bud tries to make plant grow taller or longer

  • if we remove apical bud, we remove the apical dominance


What are leaves

What are leaves?

  • undergo photosynthesis, exchange gases


What is the difference between a simple leaf and a compound leaf

What is the difference between a simple leaf and a compound leaf?

  • simple leaf = 2 parts (leaf blade and petiole)


What is the difference between a simple leaf and a compound leaf1

What is the difference between a simple leaf and a compound leaf?

  • Compound leaf: leaf blade divided into leaflets


What are the different types of compound leaves

What are the different types of compound leaves?

  • Palmately compound


What are the different types of compound leaves1

What are the different types of compound leaves?

  • Pinately compound


What are the different types of compound leaves2

What are the different types of compound leaves?

  • Trifoliate (alfalfa)


What is the hypocotyl

What is the Hypocotyl?

  • part of the plant below the cotyledonary node


What purpose does the hypocotyl serve

What purpose does the hypocotyl serve?

1) anchor plant

2) absorb water & nutrients

3) store food


What are the types of root systems

What are the types of root systems?

-Taproot: one main root, has no nodes

  • (carrot, evergreen, kochia)

    -Fibrous root: many nodes, branching root system (grasses)


To help prevent soil erosion which root system would be best

To help prevent soil erosion, which root system would be best?

  • Fibrous


What are the parts of a grass plant

What are the parts of a grass plant?

  • Leaves = Sheath is the part of leaf that wraps around the stem

  • Joints = internodes

  • Culm = stems


Grass plant parts

Grass Plant Parts

  • Tillers = branches, all branch from the base of the plant

  • Crown = union of roots and stem

  • Jointing stage = stems elongate rapidly
