please give me.
Answers
Answer:
Cotyledon: In some plants, this contains high quantities of starch and will provide a source of food for the developing embryo prior to germination, in other plants this role is performed by an endosperm. ... Radicle: This is the embryonic root which will develop into the primary root of the plant.
Answer:
1)→Cotyledons are the embryonic part of the seeds of flowering plant which upon germination forms the first green leaf and help in the photosynthesis.
→Cotyledon is an important part of the seed and helps in its germination.
→ They are part of embryo within seed and store nutrients in them
→These are the first leaves produced by plants but are not true leaves.
→ They feed plant till true leaves develop and begin photosynthesis.
2) he ovary wall, the stile and stigma degenerate when the ovary wall becomes a fruit. Functions of fruit? To entice animals to eat the fruit and carry the seeds away from parent plant. In some cases, the fruit helps to protect the seed.
3)The endosperm is a tissue produced inside the seeds of most of the flowering plants following fertilization. It is triploid in most species. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. This can make endosperm a source of nutrition in animal diet.
4) reproduction
In a flower, this landing zone and entrance is the stigma. It plays a pivotal role in reproduction. Most stigmas are adapted to trap pollen with hairs, flaps and other surfaces to increase their efficiency. Most stigmas are covered with a waxy, sticky substance.
5)The main function of the stamen is to produce the pollen grains, which house male gametes, or sex cells, necessary for reproduction. The anther is located within the stamen where these gametes are created. Pollen grains vary in size, shape, and surface structures based on the type of flower that produces them.
6)Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. Together, all of the petals of a flower are called a corolla. The main function of flower petals is to attract pollinators such as butterflies, bees and bats.
