Which of the following statement is true about the life cycle of flowering plants?

A) The sporophyte is diploid.
B) The sporophyte produces two different types of spores.
C) The male gametophyte is the pollen grain.
D) The female gametophyte is retained within the body of the sporophyte parent generation.
E) All of the answer choices are true.

A) The sporophyte is diploid. This is true, as the sporophyte generation of flowering plants is diploid.
B) The sporophyte produces two different types of spores. This is also true, as the sporophyte produces both male and female spores (pollen and ovules).
C) The male gametophyte is the pollen grain. This is true, as the male gametophyte develops into the pollen grain.
D) The female gametophyte is retained within the body of the sporophyte parent generation. This is partially true, as the female gametophyte is retained within the ovule, which is part of the sporophyte generation.
Therefore, all the answer choices are true.
