- eukaryotic cells and organelles
- has a nucleus and membrane-bound organelles (except ribosomes)
- in complex organisms they become specialised for specific functions
- vacuole (plants) - fluid filled sac that contains sugars/ amino acids
- lysosomes - contains lysozymes
- hydrolyse material ingested by phagocytic cells
- release enzymes to the outside of cell (exocytosis)
- digest worn out chemicals
- enzymes which hydrolyse the cell wall of certain bacteria
- golgi apparatus - modifies and transports molecules
- adds carbohydrates to proteins to form glycoprotiens
- produces secretary enzymes
- forms lysosomes
- mitochondria - site of aerobic respiration
- the space in the middle is the matrix
- the folds are the cristae
- chloroplasts (plants and algae) - site of photosynthesis
- thylakoid contains chlorophyl
- stroma is the fluid that surrounds everything
- cells wall ( in plants and algae) - provides strength (microfibrils) and stopes cell from bursting
