Egg or sperm produced by meiosis
WebThe realization that gametes are haploid, and must therefore be produced by a special type of cell division, came from an observation that was also among the first to suggest that chromosomes carry genetic information. In 1883, it was discovered that, whereas the fertilized egg of a roundworm contains four chromosomes, the nucleus of the egg and … WebMeiosis happens only with sex cells. (true) The sex cells, sperm or egg, have the same number of chromosomes as all other cells in the body. (false – they have half) Two daughter cells are formed from meiosis. (false - 4 daughter cells) The daughter cells are new sperm and eggs. (True)

WebWhat would be the result of fertilization if egg and sperm were produced by mitosis rather than meiosis? The resulting offspring would have twice as much DNA as the parents. The resulting offspring would have the same amount of DNA as the parents. The resulting offspring would have half the amount of DNA as the parents. Question 2 WebIn angiosperms, are sperm and eggs produced by mitosis or meiosis? Which cells are spores? Which structures are gametophytes?
WebThe generative cell travels through the tube to the egg and divides mitotically to form two sperm cells. One sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm , which serves as a source of nutrition for the developing embryo.
