cell structures and functions Flashcards
What is the function of ribosomes?
protein synthesis
What is the function of the nucleus?
controls activity of the cell (stores genetic information)
What is the function of mitochondria?
- where aerobic respiration occurs
- stores energy from respiration
What is the function of the cytoplasm?
where metabollic reactions occur
What is the function of chloroplasts?
-photosynthesis
-have chlorophyll where light dependent reactions occur
What is the function of the plasma membrane?
- controls organelles entering/leaving the cell
What is the function of the large permanent vacuole?
- regulates osmosis
-contains cell sap, maintenance of turgor, rigid framework of cell - membrane of vacuole = tonoplast
What is the function of the cell wall?
- provides tensile strength
(defence mechanism against pathogens)
What is the function of the vesicles?
-transport and store molecules
(secretary vesicles)
What is the function of the nuclear pores?
- transport molecules in and out of nucleus
What is the function of the centrioles?
- produce the cytoskeleton
What is the function of the golgi apparatus?
- modify proteins and package them into vesicles
- always near vesicles
-side where vesicles enter, fuse with golgi = cis face
side where they leave = trans face
structure - stack of cisternae
What is the function of the rough endoplasmic reticulum?
- ribosomes bound to the surface and responsible for synthesis and transport of proteins
What is the function of the cisternae?
-tunnels
- responsible for transport
What is the function of the smooth endoplasmic reticulum?
- responsible for lipid and carbohydrate synthesis and stores them
