Parts of a Plant | Functions of Plant Parts

A plant is made up of many different parts. The three main parts are the roots, the leaves, and the stem. Each part has a set of jobs to do to keep the plant healthy. The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground and carries water and minerals to the leaves. The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.

Plant Forms

Aquatic plants: are plants that have adapted to living in aquatic environments (saltwater or freshwater ). They are also referred to as hydrophytes or macrophytes. These plants require special adaptations for living submerged in water, or at the water’s surface. 

The principal factor controlling the distribution of aquatic plants is the depth and duration of flooding. However, other factors may also control their distribution, abundance, and growth form, including nutrients, disturbance from waves, grazing, and salinity. One of the largest aquatic plants in the world is the Amazon water lily; one of the smallest is the minute duckweed. Many small aquatic animals use plants like duckweed for a home, or protection from predators, but areas with more vegetation are likely to have more predators. Some other familiar examples of aquatic plants might include floating hearts, water lilies, lotus, and water hyacinths.

Terrestrial plants:  These are plants that grow on/in or from land.
