FLS2731 Lecture 1: Cell Organelles Notes
Document Summary
Nucleus description: membrane-bound structure inside eukaryotic cells that contains dna. function: runs all of the functions inside the cell. endoplasmic reticulum description: network of tube-like canals. There is smooth and rough er. function: smooth er makes hormones and controls calcium release. Rough er is covered in ribosomes and makes proteins. golgi bodies description: a system of flattened membrane sacs. function: packages substances for transport inside or out of the cell. Mitochondria have their own dna. function: where cellular respiration takes place. Releases energy from glucose for the cell. lysosome description: small spherical organelles free floating in the cytoplasm. Found mostly in animal cells. function: contains digestive enzymes that dissolve cellular waste. Acts like a garbage disposal system. vacuole description: membrane bound sacs. Usually much larger in plant cells. function: used to store water, food or waste. Similar to our skeletal system. cell membrane description: thin membrane that surrounds the cell.
