What distinguishes gymnosperms from angiosperms?

Gymnosperms are distinct from angiosperms primarily because they lack flowers and fruits. This characteristic is fundamental to the classification of these two groups of seed-producing plants. Gymnosperms produce seeds that are not enclosed within an ovary, which is a key feature of angiosperms. Instead, their seeds are often found on the surface of cone scales or other structures, making them "naked seeds," hence the name "gymnosperm," which means 'naked seed' in Greek.

Understanding this distinction is crucial in plant biology, as it highlights the evolutionary adaptations that have occurred in the plant kingdom. Angiosperms, by contrast, have evolved to produce flowers that facilitate the process of pollination and fruits that assist in seed dispersal. This difference in reproductive structures is a significant factor in how these plants adapt to their environments and interact with pollinators and other organisms.

The other options do not accurately represent the defining features of gymnosperms compared to angiosperms and thus do not contribute to this distinction. For example, the idea that gymnosperms reproduce through spores is incorrect, as both gymnosperms and angiosperms primarily reproduce via seeds. Additionally, all vascular plants,
