Outline the pathway taken by water through the root, stem and leaf, limited to: root hair cells, root cortex cells, xylem and mesophyll cells

Identify and label the cuticle, cellular and tissue structures of a dicotyledonous leaf, as seen in diagrams or photomicrographs, and explain how these structures are adaptations for photosynthesis and gas exchange, limited to: (a) stomata and guard cells (b) spongy and palisade mesophyll cells (c) air spaces (d) vascular bundles (xylem and phloem) (e) distribution of chloroplasts (f) upper and lower epidermis

Understand that water evaporates from the surfaces of the mesophyll cells into air spaces and then diffuses out of the leaves through the stomata as water vapour
