Question 20

Compare and contrast homospory and heterospory. Which reproductive structures result from meiosis in each type of life cycle, and which structures result from mitosis?

Accepted Answer

Homospory and heterospory are two different reproductive strategies found in plants.

Homospory is a reproductive strategy in which a single type of spore is produced, which gives rise to a bisexual gametophyte. This means that the gametophyte produces both male and female gametes. In homosporous plants, meiosis results in the production of spores, and mitosis results in the development of the gametophyte.

Heterospory, on the other hand, is a reproductive strategy in which two types of spores are produced: microspores, which give rise to male gametophytes, and megaspores, which give rise to female gametophytes. In heterosporous plants, meiosis results in the production of both types of spores, and mitosis results in the development of the gametophytes.

In summary, homospory results in the production of a single type of spore and a bisexual gametophyte, while heterospory results in the production of two types of spores and separate male and female gametophytes. Meiosis produces the spores in both types of life cycles, while mitosis produces the gametophytes.
