Plants have adapted to live in different environments. Terrestrial plants that live in hilly areas have adaptations like tall, straight trees with needle-like leaves and cones instead of flowers. Plants in hot, damp areas are evergreen with many leaves to retain water without shedding. Aquatic plants like floating plants protect small water animals from sun with light structures, while fixed plants have broad, stomata-bearing leaves only on top and stems that attach to pond beds. Underwater plants have ribbon-like leaves without stomata and breathe through their bodies. Grass family plants like cereals provide food, while unusual plants like insectivorous plants trap and consume insects.
