The correct answer is: The tetraploid (4n) flower produces 2n gametes and may then be able to self-pollinate to produce fertile 4n offspring.
Gametes are produced via meiosis, which is reduction cell division, meaning that cell from diploid (2n) becomes with haploid (n) number of chromosomes. In the example above, 4n flower will produce 2n gametes. Ovary of the flower produces ovule-the female gamete which is ready for fertilization. The anther produces pollen that lands on a mature stigma of a flower and grows a pollen tube down into the flower. Pollen then produces male gametes-sperm by mitosis and releases them for fertilization.
A group of compounds that pass electron from one to another via redox reactions coupled with the transfer of proton across a membrane to create a proton gradient that drives ATPsynthesis. It is located in the inner membrane of the mitochondria.
Answer:
Gene expression is a strictly controlled process that allows a cell to respond to changes in its surroundings. It serves as an on/off switch for controlling when proteins are created as well as a volume control for increasing or decreasing the amount of proteins produced.
