Eukaryotic cell organelles Recognising eukaryotic cells and their functions. 5.0 / 5 based on 5 ratings ? BiologyCellular processes and structureASOCR Created by: Kishore3Created on: 06-09-14 00:23 Nucleus Largest organelle in size. It's the processing centre of the cell; contains most genetic material and controls the activity within the cell. 1 of 14 Nucleolus Spherical structure centered in nucleus. Manufactures RNA components (proteins) 2 of 14 Nuclear envelope Surrounds nucleus. Double membrane with pores to regulate passage. 3 of 14 Rough endoplasmic reticulum (RER) Continuous with the nuclear envelope and has ribosomes attached to their membranes. Manufactures and synthesises proteins. 4 of 14 Smooth endoplasmic reticulum (SER) Continuous with the nuclear envelope with no attached ribosomes. Used for lipid synthesis and processes a variety of metabolic processes. 5 of 14 Golgi apparatus/body Individual/separate organelle with folded membranes. Modifies proteins received from RER and packs them into vesicles to be transported. 6 of 14 Ribosomes Tiny spot-like looking organelles. Used for protein synthesis. 7 of 14 Mitochondria Spherical or sausage shaped with a double membrane. This is where ATP is made. 8 of 14 Lysosomes Spherical; like sliced olives. Contains digestive enzymes and breaks down waste products. 9 of 14 Chloroplasts Only in plants and contains thylakoids. Used for photosynthesis. 10 of 14 Plasma (cell surface) membranes Surrounds cell as a layer. Made of phospholipid layer and controls entry and exit of specific substances into the cell. 11 of 14 Centrioles Star shaped tubes (usually a pair next to nucleus of animal cells). Forms spindle fibres for mitosis cell division. 12 of 14 Flagella Hair-like extensions from cell surface. They move whole cells along (eg.sperm) 13 of 14 Cilia Hair-like extensions from cell. They move substances along (eg.mucus) 14 of 14
