Hi everybody!Im going to share with you about roots.In vascular plants,the root is the organ of a plant that typically lies below the surface of the soil.The first root that comes from a plant is called the radicle.The two major functions of roots are 1)absorption of water and inorganic nutrients and 2)anchoring of the plant body to the ground.
In response to the concentration of nutrients, roots also synthesise cytokinin, which acts as a signal to how fast the shoots can grow.Roots often function in storage of food and nutrients.The roots of most vascular plant species enter into symbiosis with certain fungi to form mycorrhizas, and a large range of other organisms including bacteria also closely associate with roots.
Sincerely,
Nur Hidayah.
