Cells Flashcards
What is the function of the cell membrane?
controls what goes into and out of the cell.
What is the function of nucleus?
controls the cells activity and has genetic material.
What does the mitochondria do?
Site of aerobic respiration which produces ATP.
What is the function of chloroplasts?
site of photosynthesis
What is the function of Golgi apparatus?
processes and packages new lipids and proteins.
- also makes lysosomes
What is the function of the Golgi vesicle?
stores lipids and proteins made at the Golgi apparatus and transports them out of the cell via cell membrane.
What is the function of lysosomes?
Contain digestive enzymes called lysozymes. They are kept away from the cytoplasm by surrounding membrane, and can be used to digest invading cells or break down worn out components of cells.
What is the function of Ribosome?
Site of protein synthesis
What is the function of the RER?
has ribosomes
- folds and processes proteins that have been made at the ribosomes.
What is the function of the SER?
synthesises and processes lipids
What is the function of the cell wall?
supports cells and prevents it from changing shape.
What is the function of the cell vacuole?
helps maintain pressure inside the cell and keeps cell rigid. - stops plant from wilting.
What is osmosis?
the movement of water across a partially permeable membrane from a High concentration to low concentration.
What is simple diffusion?
CO2 diffuses out of the cell into the blood from an area of high concentration to low concentration
What is facilitated diffusion?
movement of substances from high concentration to low concentration using a carrier protein.
