Answers
Explanation:
1)Germination is the process of seeds developing into new plants. ... When water is plentiful, the seed fills with water in a process called imbibition. The water activates special proteins, called enzymes, that begin the process of seed growth. First the seed grows a root to access water underground.
2)Internal structure — The seed is covered by a hard, tough covering called testa. Inner to the tests is the embryo. Embryo consists of two cotyledons and embryo axis. ... The plumule is present in between the two cotyledons and its top bears two folded tiny leaves.
3)The Differences Between Rabi and Kharif Crops. Rabi crops are sown at the end of monsoon or the beginning of winter. ... Kharif crops are sown at the beginning of the rainy season and are also known as monsoon crops. Flowering requires a long day length.
4)Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
4)The main steps for agricultural practices include preparation of soil, sowing, adding manure and fertilizers, irrigation, harvesting and storage.
