Exploring the Plant Kingdom

Plants are abundant on Earth, with over 255,000 species and new ones being discovered. They are composed of cells and perform photosynthesis to create food. The plant kingdom includes various categories such as mosses, ferns, conifers, and flowering plants. Mosses thrive in moist areas, ferns reproduce via spores, and conifers, often called evergreens, reproduce from seeds in cones. Flowering plants, which produce seeds within flowers, are crucial for human consumption.
