Question

Suggest why the cells in the lower epidermis of the leaf (apart from the guard cells) do not contain chloroplasts.

Answer 1

Answer:

Explanation:The guard cells are bean-shaped in surface view, while the epidermal cells are irregular in shape. The guard cells contain chloroplasts, so they can manufacture food by photosynthesis (The epidermal cells of terrestrial plants do not contain chloroplasts) Guard cells are the only epidermal cells that can make sugar.

Answer 2

Answer:

Transparent waxy cuticle – a protective layer that allows light to enter the leaf. It is waterproof in order to prevent water loss by evaporation. Epidermis – transparent, physical defence layer that does not contain chloroplasts. ... These cells also have many chloroplasts in order to trap as much light as possible.
