R&B · from “Biology: The Cell” notes
Read the corrected notes
- Living organisms consist of one or more cells.
- The cell is the basic unit of life; new cells arise from existing cells.
- Bacteria and archaea are prokaryotes. Their cells lack a nucleus and membrane-bound organelles, but they do have ribosomes.
- Animals, plants, fungi and protists are eukaryotes. Eukaryotic cells typically have a nucleus and membrane-bound organelles.
- The cell membrane contains a phospholipid bilayer and proteins. It selectively regulates movement into and out of the cell.
- In eukaryotic cells, most DNA is in the nucleus. Mitochondria and chloroplasts also contain their own DNA.
- Mitochondria produce ATP during cellular respiration. ATP transfers energy for cellular work.
- Ribosomes make proteins in both prokaryotic and eukaryotic cells.
Notes match the corrected lyrics. Biology references: OpenStax, Biology 2e, cell theory and prokaryotic cells.
