One difference between cell division in plant cells and in animal cells is that plant cells have a. centrioles. b. centromeres c. a cell plate. d. chromatin. 12. During normal mitotic cell division, a parent cell having four chromosomes will produce two daughter cells, each containing a. two chromosomes. b. four chromosomes c. eight chromosomes. d. sixteen chromosomes. 13. If a cell is in G2 a) it has twice the amount of DNA present in a telophase nucleus b) it has visibly distinct chromosomes. c) it lacks a visible nuclear membrane. d) it is in mitosis. e) it is in cytokinesis.Explanation / Answer
6) The correct answer is option B that is S phase because DNA synthesis occurs in S phase.
G1 is before S phase.
G2 is after S phase.
G0 is before G1 phase.
7) The correct answer is option A that is monohybrid cross.
Test cross is cross with cross with recessive parents.
Back cross is with the main parents.
8) Option B is the cocorre answer that is 3:1
9) Option D is the correct answer that is formation of the cell plate
