stmarysajmer.org• Adaptations are the special features that help a plant to survive in its habitat. • Plants can be divided into major groups: (A) Water or aquatic plants (B) Land or Terrestrial plants. • Plants that grow in water are called aquatic plants. There are two types of aquatic plants —-floating plants, fixed plants and underwater.
