The gametophytes of an unknown plant are contained within the sporophyte, and the plant produces separate male and female gametophytes. Which the following is the best conclusion about the life cycle of this plant?

a. The plant is a fern, and the gametophyte is its dominant phase.

b. The plant is a gymnosperm, and the sporophyte is its dominant phase.

c. The plant is a moss, and the sporophyte is its dominant phase.

d. The plant is an angiosperm, and the gametophyte is its dominant phase.

The correct answer will be option-B.

Explanation:

The life cycle of plants is divided into two phases - the sporophyte phase represented by the green plant we see which produces spores and the gametophyte phase which produces gametes.

The life cycle which produces separate male and female gametophytes belongs to the gymnosperm division of the plant kingdom. The male gametophyte of the gymnosperms is known as the micro gametophyte whereas the female gametophyte is known as the macrogeamteophyte.

Thus, Option-B is the correct answer

the best answer is B
