Cell Organelles 2.0 / 5 based on 1 rating ? BiologyCellular processes and structureASEdexcel Created by: Julie SimpkinCreated on: 03-05-13 08:59 Nucleus structure Nuclear envelope (double membrane), contains pores, contains chromatin and nucleolus 1 of 13 Nucleus function Pore allow substances (RNA) to move between the nucleus and cytoplasm. The nucleolus makes ribosomes 2 of 13 Lysosome structure Round organelle, surrounded by membrane 3 of 13 Lysosome function Contains digestive enzymes, break down worn out/old cells 4 of 13 Vesicle structure Fluid filled sac, surrounded by a membrane 5 of 13 Vesicle function Transports substances in and out of cells. Some are formed in the golgi body or endoplasmic reticulum 6 of 13 Ribosome structure Small, floats free in the cytoplams, attaches to the rough endoplasmic reticulum 7 of 13 Ribosome function Site of protein synthesis 8 of 13 sER and rER structure System of membranes, rER covered in ribosomes 9 of 13 sER and rER function sER synthesises and processes lipids, rER folds and processes proteins that have been made at the ribosomes 10 of 13 Golgi apparatus structure Flattened sacs, vesicles often seen at the edges 11 of 13 Golgi apparatus function Processes and packages new lipids and proteins. Makes lysosomes 12 of 13 Centriole structure Hollow cylinders, contain ring of microtubules 13 of 13
