Which of the Following Statements Correctly Describes a Portion of the Pine

Question

Which of the following statements correctly describes a portion of the pine life cycle?
A)Female gametophytes use mitosis to produce eggs.
B)Seeds are produced in pollen-producing cones.
C)Pollen grains contain female gametophytes.
D)A pollen tube slowly digests its way through the triploid endosperm.

Accepted Answer

In the pine life cycle, female gametophytes are located within the ovules inside the ovulate cones. These gametophytes produce eggs through mitosis. Pollen grains contain male gametophytes (sperm nuclei) that fertilize the eggs produced by the female gametophytes. Seeds are produced in the ovules after fertilization occurs, not in pollen-producing cones. The pollen tube grows from the pollen grain and delivers the sperm nuclei to the female gametophyte, not through the triploid endosperm.
