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.
Summary. The plant body is composed of cells and their products. All plant cells are surrounded by a rigid cell wall that is produced by the cell. Inside the wall is the cell membrane, which selectively regulates the movement of materials into and out of the cells.Plant cells are compartmentalized into organelles that are structurally organized to support their function.The nucleus, chloroplast, ribosomes, and vacuole are examples of plant cell organelles.nside the wall is the cell membrane, which selectively regulates the movement of materials into and out of the cells.
