Comparison of plant and animal cells.

Plants and animals are eukaryotes. This means that they have in the structure of their cells various membrane organelles, that is, organelles that are separated from the cytoplasm by means of a membrane. The main organelle, which is found in both animal and plant cells, is the nucleus. But not all animal and plant cells have nuclei. For example: human erythrocytes are devoid of a nucleus, as well as the conducting cells of plants. The differences are associated with the functions of cells and the fact that plants are autotrophs, and animals are heterotrophs.
