Question

How much would a seed grow if you cut off the cotyledon compared to a seed with the cotyledons still there?

Answer 1

Generally slows the growth down some, but not as badly as you might think in a plant where the nutrient reserve is not in the cotyledons (i.e., in a plant with copious endosperm).  In plants where much of the storage reserve is in the cotyledon (many beans, for instance), you've nearly cut the nutrient reserves in half by losing a cotyledon early in germination.

If the seedling has progressed to a couple of true leaves before the cotyledon is removed, you're not going to see much difference.

Answer 2

A cotyledon gives nutrients to a seedling as the plant cannot perform photosynthesis yet. It also serves as the first leaves of the plant. If you check in your biolog/science textbook, thereis bound to be enough info on it
