Biology Honors Prentice Hall Textbook by Miller/Levine Chapter 7 Cheat Sheet • Cell theory states: all living things are composed of cells, cells are basic unit of structure and function in living things, and new cells are produced from existing cells. • Prokaryotic cells do not have a nucleus, and instead their DNA is in the cytoplasm. Eukaryotes have a nucleus, and their DNA is stored in the nucleus. • Parts of the eukaryotic cell: nucleus (has chromatin, nucleolus, and directs cell. DNA replication, transcription, and splicing occurs), cytoplasm (portion of cell outside nucleus), ribosomes (small particles of RNA and protein which determine the roughness of E.R.), E.R. (rough ER synthesizes proteins, smooth ER- no ribosomes- makes lipids), Golgi apparatus (proteins are packaged for storage or secretion outside cell), lysosomes (digests/ breaks down particles, has acidic pH), chloroplasts (capture light energy and make glucose), mitochondria (extracts energy from glucose to make ATP), and
