Leaves and diffusion
Cards in this deck (4)
- 1The structure of a leaf
- 2Respiration and photosynthesis in leaves
- 3Diffusion in leaves - photosynthesis1)When the plant is photosynthesising it uses up lots of carbon dioxide, so there's hardly any inside the leaf.
2)Luckily this makes more carbon dioxide move into the leaf by diffusion.
3)At the same time lots of oxygen is being made as a waste product of photosynthesis.
4)Some is used in respiration, and the rest diffuses out of the leaf. - 4Diffusion in leaves - respiration1)At night it is different. There's not photosynthesis occuring because there is no light. Lots of carbon dioxide is made in respiration and lots of oxygen is used up.
2)There's a lot of carbon dioxide in the leaf and not a lot of oxygen, so now it's mainly carbon dioxide diffusion out and oxygen diffusion in.
