The correct term to complete the sentence. Introduction : The conifers are heterosporous, they form two spores one develops into male and other into female gametophyte. The female cone has two ovules, each undergo meiosis in the megasporangium and form four megaspore. Three of them get disintegrated and the remaining megaspore undergo mitotic division and form female gametophyte. The male cone are the pollen grains undergo meiosis and form micropores as they have small reproductive scale. The pollen grains are transported to the female reproductive part through air or wind. If this pollen falls near the micropyle that is the opening of the ovule, it gets trapped in a sticky substance termed as pollen drop. Once the pollen drop gets absorbed inside the ovule, the pollens is pulled close to the micropyle and there the pollen grain continue to develop.

Once the pollen drop gets absorbed inside the ovule, the pollens is pulled close to the micropyle and there the pollen grain continue to develop.

Expert Solution & Answer

Explanation of Solution

The megaspore of conifers is a female reproductive structure. There are four megaspore present.Among that, three get disintegrated and one will form the female gametophyte. The pollen grains are the male gametophyte that is developed from microspore after the meiotic cell division. Therefore, the correct word will be microspore for the given statement.

Conclusion

The microspore of a conifer develops into the pollen grain not megaspore.
