How do seeds provide an advantage in plant sexual reproduction? Select all that apply.
a. produce food through photosynthesis
b. embryo protection
c. gamete development until water is available
d. long periods of dormancy until good conditions provide nourishment

b. embryo protection

d. long periods of dormancy until good conditions provide nourishment

Explanation:

Seeds can be defines as a fertilized ovule which contain an embryonic plant.

Seeds provide several advantages in plant sexual reproduction including embryo protection and long periods of dormancy until good conditions provide nourishment.

Seeds contain an embryo which furthur germinates into sporophyte. Seeds are served to protect the embryo when the embryo produces genetic variability and range.

Seeds remain in long period of dormancy until the favorable conditions for growth which is induced by desiccation and the hormone abscisic acid.

Hence, the correct answers are  b. "embryo protection" and d. "long periods of dormancy until good conditions provide nourishment".

it's     c       this is a cell (b) with a nucleus (c) containing dna (a). the dna is organized into chromosomes (d). a section of the chromosome that codes for a trait is called a gene (e).
