The fact that plants can be cloned from somatic cells demonstrates that

Differentiated cells retain all the genes they had before development

Explanation:

Plant cells have the ability to keep their plasticity and development potentialities after fully develop, this means that they can dedifferentiate and assume different cellular phenotypes. This differentiation responds to endogenous stimuli modifying the gene program of the cell resulting in whichever cell the researches want, this makes possible the somatic cloning.

I hope you find this information useful and interesting! Good luck!

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )
