What defines a gymnosperm?

1. A plant that produces unprotected seeds

2. A fruit-bearing plant

3. A plant that undergoes photosynthesis

4. A plant that reproduces solely via spores

The correct answer is: A plant that produces unprotected seeds

A gymnosperm is specifically defined as a plant that produces unprotected seeds, which is the primary characteristic that distinguishes it from other types of plants. Unlike angiosperms, which are flowering plants that produce seeds encased in fruit, gymnosperms produce seeds that are not enclosed within a fruit. These seeds are typically found on the surface of cones or other structures. This unprotected nature of the seeds is a critical aspect of gymnosperms, which includes groups such as conifers, cycads, ginkgoes, and gnetophytes. The other options highlight different characteristics of plants. Fruit-bearing plants refer to angiosperms, making this choice not applicable to gymnosperms. Regarding photosynthesis, while all plants do undergo this process, it is not a defining feature of gymnosperms specifically, as it applies to all plants. Lastly, reproduction solely via spores is a characteristic associated with non-seed plants such as ferns and mosses, which do not fall under the category of gymnosperms. Therefore, the answer centers around the unique aspect of gymnosperms producing unprotected seeds.
