Answer 2

For the formation of 140 angiospermic seeds, 280 meiotic cell divisions are expected.

Explanation: Pollination, the transfer of pollen from an anther to a stigma on the same flower or to the stigma of another flower on the same plant (self-pollination), or from an anther on one plant to the stigma of another plant, is the first step in angiosperms(flowering plants) reproduction (cross-pollination).

A male gametophyte must go through one meiosis and two mitoses in order to develop.

A female gametophyte must undergo one meiosis and three mitoses in order to develop.

Both a male and a female gametophyte are present in a single angiosperm seed.

This means that $1+1=2$ meiosis will be needed to create 1 angiosperm seed.

Consequently, $140\times 2=280$ mitosis will be needed to create 140 angiosperm seeds.

The right answer is therefore b.280.
