where do mitosis and meiosis occur in animal and plants?
Difference between chromosomes and chromatin?
what is kernplasma ratio?
plants dont have centrioles, so how are the spindle fibres formed for cell division? how can it divide without centriole? n if it can , why do animals need the centriole? What is its main function? arent spindle fibres formed by centriole? if nt then wer r they formed?

What is DNA replication?
cell division includes karyokinesis and cytokinesis. at what phase does the cytokinesis process BEGIN.?is it at the end of telophase, starting of telophase, end of prophase or starting of prophase?
synapsis (b) bivalent (c) chiasmata
a diagram to illustrate your answer.

b) maintaing constancy in no. of diploid chromosomes during sexual reproduction
c) production of genetic variability in population of species
d) all of above
