1
Q
Define eukaryotic cell
A
DNA is contained in a nucleus, contains membrane bound specialised organelles
2
Q
Define prokaryotic cells
A
DNA is ‘free’ in the cytoplasm, no organelles e.g. bacteria and archaea
3
Q
State the relationship between a system and specialised cells
A
Specialised cells –> tissues that perform specific function –> organs made of several tissue types –> organ system
4
Q
What is the cell surface membrane?
A
‘Fluid mosaic’ phospholipid bilayer with extrinsic and intrinsic proteins embedded
5
Q
Describe the structure and function of the cell surface membrane
A
- Isolates cytoplasm from extracellular environment
- Selectively permeable to regulate transport of substances
- Involved in cell signalling/cell recognition
