<h3>What are cells?</h3>
  • Cells are the basic building blocks of all living things. The human body is comprised of trillions of cells. They deliver structure for the body, take in nutrients from food, convert those nutrients into significance, and carry out technical functions.
  • Cells are of two types: eukaryotic, which include a nucleus, and prokaryotic cells, which do not have a nucleus, but a nucleoid province is still present. Prokaryotes are single-celled organisms, while eukaryotes may be either single-celled or multicellular.
  • They deliver structure for the body, take in nutrients from food, convert those nutrients into significance, and carry out technical functions. Cells also include the body's genetic material and can make duplicates of themselves. Cells have multiple parts, each with a separate function.
