These notes contain a summary of key facts. When revising, you will still need to refer to your jotter to
remind yourself of the experimental and practical work you have done.
LHS- Cell Biology Unit Summary Notes
, Cells and Cell Structure
Cells are the building blocks of life.
All living organisms are made up of cells.
Cells need to be viewed through a microscope.
Plant cells and Animal cells
Fungal cell e.g. yeast
LHS- Cell Biology Unit Summary Notes
, Bacterial Cell
Bacteria cells do not contain any organelles
plasmid
Cell structure Function
Contains genetic information (DNA) in animal, plant and
Nucleus
fungal cells
Plasmid A small ring of DNA only found in bacterial cells
Controls entry and exit of substances such as oxygen and
Cell membrane
carbon dioxide.
Liquid inside cells containing organelles, the site of various
Cytoplasm
chemical reactions
The outer layer of plant, fungal and bacterial cells which
Cell Wall
helps support the cell
Membrane bound sac that stores a solution of water found in
Vacuole
plant and fungal cells
Main site of energy (ATP) production in aerobic respiration in
Mitochondrion
animal plant and fungal cells
Chloroplast The site of photosynthesis in plant cells
Ribosome Site of protein synthesis in cells
Cell walls of plant, fungal and bacterial cells are not all the same. They are made of
different chemicals.
