Question

how does a growing embryo inside a seed obtain food? it uses food stored within the seed. it undergoes photosynthesis to make its own food. it absorbs food from the outside environment. it takes in food provided by the seed coat.

Explanation:

A seed has stored food in the cotyledons or endosperm. The embryo uses this stored food for growth. It can't perform photosynthesis as it's inside the seed (no light access). The seed coat is a protective layer, not a food - providing source. And it can't absorb food from the outside environment at this stage as it's enclosed within the seed.

Answer:

It uses food stored within the seed.
