                     Chapter at a Glance

                      ³  Plants grow in different shapes, sizes and forms all over the world.

                      ³ Aquatic plants are plants that grow in water. They can be fully underwater, fixed,
                           free-floating or emergent.

                      ³ Plants that grow on land are called terrestrial plants.

                      ³ Insectivorous plants eat insects to get nutrition.

                      ³ The desert areas have little rainfall, therefore fewer plants grow there.
