What type of spore plants produces only one type of spore?

The correct answer is associated with plants that produce only one type of spore, which is known as homosporous. In homosporous plants, the single type of spore typically develops into a gametophyte that can produce both male and female gametes, facilitating both sexual reproduction and genetic diversity within a population.

Homosporous plants are commonly found among certain groups of ferns and mosses, where the spores are usually uniform in size and shape, allowing them to propagate and grow into a gamete-producing structure that can give rise to offspring. This form of reproduction is important for the life cycle of the plant, as it maintains the ability to adapt to their environment while relying on a singular spore type.

In contrast, heterosporous plants produce two distinct types of spores (microspores and megaspores), which develop into male and female gametophytes, respectively. Understanding the differences between these reproductive strategies is essential for grasping plant biology and evolution.
