Seed
The seed is the root part of a plant, which is found enclosed within the fruit. It is composed of a seed coat and an embryo. The wall of the ovary becomes the pericarp during the development of the fruit. In some plants, the ovary wall dries up completely, while in some it remains fleshy.
Types of Seeds
On the basis of the number of cotyledons, the seeds are further classified into two types – dicot and monocotyledonous seeds.
- Monocotyledonous— The embryo has an embryonic axis and contains only one cotyledon. Cereals, including rice, millet, wheat, and other plants such as onions, maize, ginger, bananas, and palm trees, are examples of monocot seeds.
- Dicotyledonous— The embryo has an embryonic axis and contains two cotyledons. Legumes including beans, lentils, peas, peanuts, and tomatoes are examples of dicot seeds.
Morphology Of Flowering Plants
Morphology of flowering plants is the study of their external structures, including roots, stems, leaves, and reproductive organs, to understand their form and function. Roots anchor the plant and absorb water and nutrients. There are three types of root systems: tap root, fibrous root System, and adventitious root System. Stems provide support and facilitate the transport of water and nutrients. Stem exhibits different modifications like runners, suckers, climbers, and cladode. Leaves are the primary sites for photosynthesis and gas exchange. Flowers form the reproductive structures of the plant. In the flower the process of fertilisation takes place, involving the fusion of male and female gametes, ultimately leading to the formation of seeds within the fruit.
