(a) Name the jelly like structure as observed by Ravi and Reena. (b) What is the function of this jelly? (c) How does the process of fertilization occur in such organisms?
and (a) Nuclear membrane is a membrane that protects the nucleus and nucleolus is a part inside the nucleus. Cytoplasm is the jelly-like substance present between the cell membrane and nucleus and centriole is a cylinder shaped structure present in the cytoplasm.
ans (b)A layer of jelly holds the eggs together and provides protection to the eggs as the eggs are exposed to water movement, wind and rainfall.
ans (c) Fertilization in advanced plants is preceded by pollination, during which pollen is transferred to, and establishes contact with, the female gamete or macrospore. Fusion in advanced animals is usually followed by penetration of the egg by a single spermatozoon
