41. The zygote forms an oocyst and within the oocyst, the sporozoites develop. 42. The diploid zygote undergoes repeated cellular division by mitosis to grow into the organism. 43. Two organisms of opposing sex contribute their haploid gametes to form a diploid zygote . 44. In land plants, the zygote is formed within a chamber called the archegonium. 45. The human zygote has been genetically edited in experiments designed to cure inherited diseases. 46. Monozygotic twins split into two zygotes at some time very early in the pregnancy. 47. The zygote contains a full complement of genetic material and develops into the embryo. 48. The resulting zygote germinates into a resting spore. 49. A zygote is formed after fertilization, which grows into a new sporophytic plant. 50. The two cells then conjugate to form a diploid zygote that may undergo meiosis.
