Without variation in traits among the population, there would be no variation in the relative fitness of individuals within the population (i.e. (higher level) no differential reproductive success between individuals). Without varying reproductive success between individuals in population based on traits, there will be no change in frequency of traits in the population over time. To put it simply, there is nothing for natural selection to act upon.

But in case of animal cell cyto skeleton is present in place of cell wall and plastid is absent because animals generally does not carry out photosynthesis.
