The primary function of plant roots is absorption of water and minerals from the soil. Most of plant roots anchor the plant in place. In some cases aerial roots help plants to absorb water from the air (in case of many species of Ficus) and also help in climbing (as in case of Smilax).he roots anchor the plant in place and prevent it from moving, being blown over or washed away by water. Absorption of water and dissolved nutrients from the soil. Root hairs increase the surface area of the roots system as a whole and enable it to absorb large amounts of water from the soil. Absorption of oxygen.
Each part of a plant has a very important function. All plants produce flowers for the same reason: to make seeds so another plant can grow.Leaves: These are the parts of the plant where food is made by photosynthesis. Leaves take in carbon dioxide from the air, water. from the soil, and energy from the sunlight.ater and minerals are taken from the soil through the roots. Many plants such as carrots, store food in their roots. Seeds: these contain a tiny embryo of a plant inside. The seed halves contain food which supplies energy and materials for growth until the plant grows its first leaves above the ground.
