cell structure and function
- a cell is the smallest unit of life – mostly made up of proteins, carbohydrates, lipids,
nucleic acids, water
- both plant and animals cells consists of a cell nucleus, cytoplasm and a cell membrane
- not all cells contain a nucleus (bacteria)
prokaryotic cell – cell without a nucleus
eukaryotic cell – cell with a nucleus
- ratio of surface area : volume is large as it facilitates the movement of substances into
and out of the cell, but the volume must be small enough for easy diffusion of substances
- all cells don’t look the same; size, shape and structure change to perform specific
functions [differentiation]
- cells become specialised to perform a specific function [specialisation]
eg: muscle cells contract and relax
