Organelles structure and function

Centrosome and centrioloes structure
Two centrioles at right angles. Each centriole is composed of 9 microtubule triplets.
1 of 20
Centrosome and centriole function
Movement of chromosomes during cell division and organisation of microtubules in cytoskeleton.
2 of 20
Cytoskeleton structure
Proteins organised in fine filaments or slender tubes
3 of 20
Cytoskeleton function
Strength and support. Movement of cellular structures and materials.
4 of 20
Plasma membrane structure
Lipid bilayer containing phospholipids, steroids, proteins and carbohydrates
5 of 20
Plasma membrane functions (5)
Isolation, protection, sensitivity, support, control entry and exit of materials
6 of 20
Microvilli structure and function
Membrane extensions containing microfilaments. Increase surface area for absorption
7 of 20
Cilia structure and function
Long extensions containing microtubule doublets in a 9+2 array. Movement of material over cell surface.
8 of 20
Proteasomes structure and function
Hollow cylinders of proteolytic enzymes with regulatory proteins at their ends. Breakdown and recycling of damaged or abnormal intracellular proteins.
9 of 20
RNA and proteins. Protein synthesis
10 of 20
Vesicles containing degredative enzymes. Catabolism of fats and organic compounds, neutralisation of toxic compounds generated in the process.
11 of 20
Vesicles conating digestive enzymes. Intracellular removsl of damaged organelles or pathogens.
12 of 20
Golgi apparatus
Stacks of flattened membranes containing chambers. Storage, alteration and packaging of secretory products and lysosomal enzymes.
13 of 20
Double membrane with inner membrane folds enclosing important metabolic enzymes. Production of ATP.
14 of 20
Endoplasmic reticulum (ER)
Network of membranous channels extending throughout the cytoplasm. Synthesis of secretory products and inracellular storage and tranport.
15 of 20
Nucleus structure
Nucleoplasm containing nucleotides, enzymes, nucleoproteins and chromatin. Surrounded by a double membrane nuclear envelope.
16 of 20
Nucleus function
Control of metabolism, storage and processing of genetic information and control of protein synthesis.
17 of 20
Site of RNA synthesis and assembly of ribosomal subunits
18 of 20
Rough ER
Protein synthesis
19 of 20
Smooth ER
Synthesises and secretes lipids and steroids
