Topic 9 : Plant Science

Topic 9.1 Plant Structure and Gowth

Draw and label plan diagrams to show the distribution of tissues in the stem

and leaf of a dicotyledonous plant

Outline 3 differences between the structures of dicotyledons and monocotyledons

Explain the relationship btw the distribution of tissues in the dicot leaf, and their functions

• Functions: Absorption of light

• Gas exchange

• Support

Identify modifications to roots, stems, and leaves for different functions: bulbs, stems tubers, storage roots, and tendrils

State that dicots have apical (primary) and lateral (secondary/cambium) meristems

• Meristems/meristematic regions of plants are mitotically active –

Lateral meristems

Explain the role of auxin (a plant hormone) as an example of the control of plant growth
