Detailed explanation-1: -Animals did not evolve from plants. Both plants and animals share a common ancestor and have grown as a result of endosymbiosis. The way their cells function provides proof of this. All animals and plants are categorized as multicellular eukaryotes.
Detailed explanation-2: -Cell theory states that the cell is the basic building block of all life forms and that all living things, whether plants or animals, consist of one or more cells. It further states that new cells can only be made from existing ones, and that organisms can grow and reproduce because their cells are able to divide.
Detailed explanation-3: -Animals and plants evolved from prokaryotes and have remained in close association with them. We suggest that early eukaryotic cells, formed by the fusion of two or more prokaryotes, already contained prokaryotic genetic information for aggregation and the formation of multicellular structures.
Detailed explanation-4: -Detailed Solution. The correct answer is All cells are identical.
