Explain how a leaf is adapted for photosynthesis

not 100% sure, but:

- leaf has stomata to let in reactants and let out waste

- has main vein to get water from ground

- leaves have a large surface area and are thin, so they can get a lot of sunlight

I haven't learned this in a while but this is what I remember

answer; ///(b) it is composed of four protein chains and four heme groups;

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
