Cell Basics
Basic unit of life
Cell
What is the nucleus?
The control centre, this organelle houses the cell's genetic material.
Carries oxygen
Red blood cell
Structure only in plant cells
Cell wall
Cells become different to perform specific roles
Specialisation
“Powerhouse” of the cell
Mitochondria
Sends electrical signals
Neuron (nerve cell)
Organelle for photosynthesis
Chloroplast
Relationship between structure and function
Structure determines function
Makes proteins
Ribosome
Contracts to cause movement
Muscle cell
Large storage structure in plant cells
Vacuole
All living things are made of these
Cells
Controls movement in/out
Cell membrane
Absorbs water in plants
Root hair cell
Both plant and animal cells have this
Nucleus
Cells arise from pre-existing…
Cells
Site of photosynthesis
Chloroplast
Why red blood cells are biconcave
Increase surface area for oxygen exchange
Gives plant cells their rigid shape
Cell wall
