Photosynthesis

Plant tissue functions Tissue Function Epidermal tissue They transport substances like water and food. Palisade mesophyll tissue Spongy mesophyll tissue Xylem and phloem Stomata Contains big air spaces to allow gases to diffuse in and out of cells. Tiny pores (holes) that allow gas exchange and water regulation Covers the whole plant Where most photosynthesis happens (in the leaf).

The Difference… _______ – the process where plants make their own food. _______ – the process where glucose and oxygen are combined to release energy for cell functions, growth and reproduction.

Conclusion • The presence of starch in leaves shows that…. • The leaves that stained positively for starch were those that were grown in … • Therefore, these result show that for photosynthesis to take place plants need…
