Which of the following statements correctly describes a portion of the pine life cycle? A) female gametophytes produce eggs via mitosis B) matured ovaries facilitate seed dispersal C) pollen grains contain female gametophytes D) seeds are produced in the pollen cones

Solution

The answer is A) and D) Female gaematophytes produce eggs via mitosis and Seeds are produced in the pine cones post fertilization.

Pine being a Gymnosperm consists of ovules which are open or naked. Within the ovules, there are cells called megasporocyte that undergo meiosis and gives rise to four cells which are haploid in nature. Of these 4 haploid cells, three degenerate and one survives to become a megaspore which contains one set of chromosomes. It is this megaspore that undergoes mitotic division to produce the Female gaematophytes which contains the egg cells.

Since the pine is a gymnosperm, the seeds are open and not covered by ovaries and therefore they do not facilitate seed dispersal.

The pollen grains contain the male gametophytes
