Transport & Adaptations of Plants

HideShow resource information
Adaptations of : palisade cell
Elongated cells which have lots of chloroplasts. Situated at the top of the leaf near the epidermis' source of light.
1 of 6
Adaptations of : upper epidermis
A relatively transparent layer of cells which allows light through to the palisade cells.
2 of 6
Adaptations of : stoma
These pores on the lower epidermis allow oxygen, water vapour & carbon dioxide to diffuse out.
3 of 6
Adaptations of : guard cells
These specialised cells change their shape to open or close the stoma.
4 of 6
Adaptations of : waxy cuticle
This layer reduces water loss from the leaf by evaporation by blocking the stomata and is a barrier to the entry of pathogenic MOs.
5 of 6
Adaptations of : spongy mesophyll
This layer of cells is loosely packed, giving a large SA for gas exchange.
