Can we find variations in an asexually reproducing organism like bacteria? Write yes or no and give a reason in support of your answer.

Give two examples each of the following:
$(a)$ Plants having unisexual flowers
$(b)$ Agents of pollination
$(c)$ Physical changes on puberty that are common to both boys and girls.

What is the advantage of reproducing through spores?

Can these two methods,regeneration and fragmentation,be equated to be the same? Answer with a reason.

What are chromosomes? Explain how in sexually reproducing organisms,the number of chromosomes in the progeny is maintained?

From the internet,gather information about the chromosome numbers of five animals and five plants. Correlate the number with the size of the organism and answer the following questions.
$(a)$ Do larger organisms have a higher number of chromosomes/cells?
$(b)$ Can organisms with fewer chromosomes reproduce more easily than organisms with a higher number of chromosomes?
$(c)$ Does a higher number of chromosomes/cells imply greater $DNA$ content? Justify.
