Note 3.1

Connect specialised cells with plant tissues, organs, transport systems and meristematic growth.

Compare epidermal, mesophyll, vascular and meristem tissues and relate structure to function.

Explain how leaves balance photosynthesis, gas diffusion and water conservation.

Explore root hairs, osmosis, active transport and the effects of mineral deficiencies.

Relate lignified xylem structure to the upward movement of water and mineral ions.

Explain water loss, environmental effects, xerophyte adaptations and potometer investigations.

Follow dissolved sugars from sources to sinks through sieve tubes and companion cells.

Compare tropisms and plant hormones, then evaluate practical and commercial applications.

Connect photosynthesis, respiration, uptake and transport across seasons and growing conditions.
