What’s inside a leaf? Accompanied by jigsaw

Looking at a leaf Can you see the stomata? Use digital microscope to look at a leaf Can you see the stomata? Label them on your picture and say what they do

Matching the parts of a leaf to their function stomata A gap that allows gases to circulate inside a leaf air space Tough outer layer of leaf to protect it vein Open and close the stomata epidermis Most of the photosynthesis happens here palisade (mesophyll) cells Carries water into the cell and glucose away guard cells A hole that allows air in and out of a leaf spongy mesophyll cells Some photosynthesis happens here – gaps between cells

Leaves are important Explain how the structure of leaves allows photosynthesis to happen. Draw a comic strip to show what happens
