Question

Figure 14.26 If a flower lacked a megasporangium, what type of gamete would it not be able to form? If it lacked a microsporangium, what type of gamete would not form?

Answer 1

There is a lack of gamete production in a plant if a flower does not have megasporangium and microsporangium.

Angiosperms are a large group of plants with flowers and yield seeds with a seed cover. These are the plants that form roots with endosperm. These are known as the dominant form of plant life in many terrestrial ecosystems. These plants comprise about 90 percent of all plant species. The two functional structures in angiosperms are the flower and the fruit.

Fertilization is when the fusion of microsporangium or haploid sperm nucleus and megasporangium or haploid female nucleus takes place to form a diploid zygote.

1. Microsporangium is the male reproductive part that gives rise to microspores. This microspore then leads to the production of the pollen grain. This pollen grain gives rise to the development of another.

2. Megasporangium is the female reproductive part that gives a megaspore. It further gives rise to an egg cell.

Usually, pollen grains and egg cells play a role in fertilization. But due to the absence of microsporangium and megasporangium, there would be no pollen grain and egg cell formation, respectively. This would result in the loss of fertilization of the plant.
