Document Summary
Phyllotaxy: the arrangements of leaves on a stem. Epidermis: single layer of cells that go around surface of the leaf to prevent water loss. Stomata: specialised pores which allow uptake of carbon dioxide from the atmosphere and release of oxygen and water. Vascular tissue: veins of the leaves including xylem and phloem of owering plants form an interconnected branching system. C4 photosynthesis: alternative photosynthesis process for plants in dry environments that uses. Pep carboxylase to create inputs for calvin cycle while preventing water loss. Leaves with a single lamina are simple leaves. Those divided into many lea ets, each with their own stalk, are compound leaves. Both are adaptations for equal illumination on both sides of the blade while at the same. Leaves account for most of the surface area of a plant. Leaves are a major interface between plants and their environment. Leaves perform the majority of photosynthesis in the plant.
