Sexual Reproduction in Flowering Plants

Question:

Both chasmogamous and cleistogamous flowers are present in which of the following option?

Options:

Rosa

Vallisneria

Oxalis

Hydrilla

Correct Answer:

Oxalis

Explanation:

The correct answer is Oxalis.

Oxalis is a genus of flowering plants that includes about 800 species. These plants are found in tropical and temperate regions around the world. Oxalis plants have two types of flowers: chasmogamous and cleistogamous.

Chasmogamous flowers are open flowers that are pollinated by insects or wind. Cleistogamous flowers are closed flowers that self-pollinate.

Oxalis plants produce chasmogamous flowers when there are plenty of pollinators around. However, if there are not enough pollinators, the plant will produce cleistogamous flowers. This ensures that the plant will still be able to reproduce, even if there are no pollinators available.

Other plants that have both chasmogamous and cleistogamous flowers include:

  • Commelina
  • Viola
