Plants are important as they provide oxygen, prevent famine, and are used for medicine. They are used in agriculture for crops like wheat and rice, as well as ornamental landscaping. The five major parts of a flowering plant are the leaves, stems, roots, flowers, and fruit. Leaves collect sunlight and facilitate photosynthesis and transpiration. Stems produce and support leaves and transport water and nutrients. Roots provide anchoring, absorb water and nutrients, and come in three types: taproots, fibrous roots, and adventitious roots. Flowers are the reproductive organ and fruit develops from the ovary to aid seed production and dispersal.
