functions of organelles

• the nucleus contains chromosomes, it controls cell activities like protein synthesis.
• in mitochondria the inner membrane is folded to increase surface area for respiration and ATP production, they are very active and need lots of energy.
• chloroplasts contain chlorophyll and are the site of photosynthesis in plant and algae.
• rough endoplasmic reticulum hold and processes proteins that were made in ribosomes.
• smooth endoplasmic reticulum synthesises and processes lipids and carbs. found in the liver and secretory cells.
• ribosomes synthesise proteins, it is found in the cytoplasm and is made of proteins and RNA.
• Golgi body is a group of fluid filled membranes, it processes and packages new lipids and glycoproteins it also makes lysosmes.
• Golgi vesicles are a small sac in the cytoplasm, it stores lipids and proteins made by Golgi body and transports them out of cells.
• lysosmes are a type of Golgi vesicle, they contain digestive enzymes (lysozymes) that digest invasive pathogens and hydrolyse white blood cells.
• cell walls support cells to prevent shape change. made from cellulose microfibrils in plants and algae and chitin in fungi.
• cell vacuole maintains pressure in cell and stops plants wilting, it also isolates unwanted chemicals and provides a temporary food store.
