Cells are the basic structure and unit of life. There are prokaryotic and eukaryotic cells. Prokaryotic cells are very basic, and have no nucleus, few organelles, and are ususally bacteria. Eukaryotic cells are more complex and have nuclei, are larger compared to prokaryotic cells, more organelles, and have emembrane bound organelles. There are plant and animals cells, each have certain organelles that other don't. For example, plant cells have large vacuoles and a cell wall; animal cells have centrioles. Cells are important because they provide strucure for the body, and take in nutrients from food and carry out many important functions, such as protein synthesis, respiration, growth and development, and more. Billions of cells make up a complex organism's body, while a single cell can make up an entire organisms, and carry out all of the needed functions. That's a quick summary of what cells are, and some of the things that they do that make them so important
