Document Summary
Cell will have more than 2 chromosomes chromosomes replicate through division, you end up with 2 diploid (vegetative cells) One parent cell divides into 4 daughter cells each with only one set of chromosomes. Homologous chromosomes form pairs (recombination occurs at this step alleles and genes of individual chromosomes interact) On each side, 4 gametes (sex cells) are formed. Occurs in an anther and an ovule. This is necessary for plant reproduction in which you take one parent cell and divide twice to form 4 haploid cells which are then capable of fusing and fertilizing an egg to make a zygote. Number of daughter cells 2 diploid (daughter cells two. 4 haploid (daughter cells are genetically different than parent cell) Produce gametes and assure genetic diversion in sexual reproduction are genetically identical to parent cells) Can continue to help cells grow and repair. Genotype: genetic makeup of plant determine phenotypic (characteristics we can outwardly observe)
