Plant Anatomy

MUPGRET Workshop

March 27, 2004

Definitions l.jpgSlide 2

Definitions

  • Anatomy

    • Study of form and basic organization.

  • Morphology

    • Study of tissue organization.

  • Physiology

    • Study of normal organism function.

Life cycle l.jpgSlide 3

Life Cycle

  • Juvenile

  • Adult

  • Reproductive

Vegetative

Plant structure l.jpgSlide 4

Plant Structure

  • Two main organ systems: shoot and root

  • Shoot

    • Above ground

    • Leaves, buds, stems, flowers, fruits

  • Root

    • Below ground

    • roots, tubers, rhizomes

Plant cells l.jpgSlide 5

Plant Cells

  • Formed at meristems.

    • Mitosis in meristem produces new cells.

  • Two types of meristems.

    • Apical – produces primary growth, ex. tip of root or shoot.

    • Lateral – produces secondary growth, ex. cambium.

Cells are grouped into tissues l.jpgSlide 8

Cells are grouped into tissues.

  • Dermal

  • Ground

  • Vascular

Dermal tissue l.jpgSlide 10

Dermal Tissue

  • Covers outer surface of herbaceous plants.

  • Composed of epidermal cells that secrete the waxy cuticle.

  • Waxy cuticle protects against water loss.

Ground tissue l.jpgSlide 11

Ground Tissue

  • Bulk of the primary plant body.

  • Composed of parenchyma, collenchyma, and sclerenchyma.

hau – used to make rope

Vascular tissue l.jpgSlide 16

Vascular Tissue

  • Transports food, water, hormone, and minerals.

  • Composed of xylem, phloem, parenchyma, and cambium.

Stem anatomy l.jpgSlide 22

Stem Anatomy

  • Bud – undeveloped shoot.

  • Node – Location of leaf or bud on stem.

  • Internode – Space between nodes.

  • Pith – Spongy tissue in the center of the stem.

  • Lenticel – Pore in the outer layer of the stem.

Slide23 l.jpgSlide 23

Stem

Stem modifications l.jpgSlide 24

Stem Modifications

  • Tuber – underground stem with nodes

  • Rhizome – underground stem with buds

  • Stolon – aboveground stem with shoot buds

  • Bulb – underground stem with fleshy leaves

  • Corm – underground stem with papery leaves

  • Vine

Growth cycle l.jpgSlide 28

Growth Cycle

  • Annual – single season

  • Biennial – two seasons

  • Perennial – multiple seasons

  • Evergreen – leaves persist > 2 seasons

  • Decidious – leaves die in cold or dry
