What are the two main categories of plants?

The correct choice identifies the two main categories of plants as flowering and non-flowering. Flowering plants, also known as angiosperms, are characterized by their ability to produce flowers and seeds within fruits. This group includes a vast variety of plants, from trees to herbs, and plays a crucial role in ecosystems by providing food and habitat. Non-flowering plants, which include ferns, conifers, and mosses, reproduce through spores or cones instead of flowers, showcasing the diversity and adaptations found in the plant kingdom.

Understanding the distinction between these two categories is fundamental in biology as it highlights the diversity of reproductive strategies among plants and their evolution.
