Answer 2

The most basic difference between cells is the division between eukaryotic and prokaryotic cells. Prokaryotic cells are simple cells that lack a cell nucleus or other membrane-enclosed structures. The cells of eukaryotes contain membrane-enclosed structures such as a nucleus and organelles. Plants and animals are eukaryotic organisms.
There is one very important similarity between prokaryotic and eukaryotic cells. Both have components that allow them to meet life’s challenges. They obtain energy and nutrients, maintain their structures, and reproduce.
