Terrestrial plants are those that grow on land, as opposed to aquatic environments. They include a wide variety of species, such as trees, shrubs, grasses, and flowering plants. These plants play a crucial role in ecosystems by providing oxygen, food, and habitat for many organisms. They typically have roots that anchor them in the soil, stems that support their structure, and leaves that capture sunlight for photosynthesis. Most terrestrial plants are adapted to survive in different climates and soil types. For example, cacti thrive in arid conditions, while ferns prefer moist, shaded areas. The diversity of terrestrial plants contributes to the overall health of the environment, supporting biodiversity and helping to regulate the climate.
