BiologyCellular processes and structureASEdexcel Created by: Corrine SCreated on: 03-05-13 08:59 Nucleus Structure Surrounded by nuclear envelope (double membrane) contains pores and chromatin and nucleolus 1 of 14 Nucleus Function Chromatin is made from proteins and DNA. pores allow substances to move between nucleus and cytoplasm. nucleolus makes ribosomes 2 of 14 Vesicle Structure Small fluid filled sack in the cytoplasm, surrounded by membrane 3 of 14 Vesicle Function Transports substances in and out of the cell and between organelles. some are formed by golgi body or endoplasmic reticulum 4 of 14 Ribosome Structure Very small organelle that floats free in the cytoplasm or is attached to rough endoplasmic reticulum 5 of 14 Ribosome Function Site where proteins are made 6 of 14 Endoplasmic Reticulum Structure A system of membranes enclosing a fluid filled space. rouch ER is covered in ribosomes 7 of 14 Endoplasmic Reticulum Function Smooth ER synthesises and processes lipids 8 of 14 Golgi Body Structure Group of fluid- filled flattened sacs. Vesicles often seen at edges of sacs 9 of 14 Golgi Body Function Processes and packages new lipids and proteins. Also makes lysosomes 10 of 14 Centriole Structure Hollow cylinders containing ring of microtubules 11 of 14 Centriole Function Involved in separation of chromosomes during cell division 12 of 14 Mitochondria Structure Oval shaped. has double membrane - inner one is folded to form cristae. inside is matrix, it contains enzymes involved in respiration 13 of 14 Mitochondria Function Site of aerobic respiration, where ATP is produced. Found in large numbers in cells that are active and require lots of energy 14 of 14
