1. Leaves

2. What’s inside a leaf?
Accompanied by jigsaw

3. 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

4. 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

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