| Seed is the basis of our agriculture. Dehydration and dormancy of mature seeds are crucial for storage of seeds which can be used as food throughout the year and also to raise crop in the next season. Seeds remain alive after they are dispersed for few to several years. Also number of seeds in a fruit can also vary. Can you think of some plants in which fruits contain very large number of seeds. Orchid fruits are one such category. Its each fruit contains thousands of tiny seeds which when dispersed produces thousands orchid plants. This is so fascinating as how a tiny structure can produce such a large biomass over the years. |
