Cell Biology
Microscopy
Types of Microscopes
Light Microscope
used to look at cells
able to see large subcellular structures e.g. nucleus
Electron Microscope
higher resolution - see in more detail
higher magnification so can see small subcellular structures e.g. ribosomes and plasmids
Magnification
magnification = image size/real size
width = 0.02 image under microscope= 8 magnification = 8/0.02 = x400
Cell Structure
Types of Cells
Prokaryotic
small and simple
e.g. bacteria cells
Bacteria Cells contain ...
Cell wall
Cell membrane
Cytoplasm
single loop of DNA
Plasmids (small rings of extra DNA)
Eukaryotic
complex
e.g. Animal and Plant cells
Animal Cells contain ...
Nucleus - contains genetic material that control what the cell does
Cytoplasm - where most chemical reactions happen
Cell membrane - controls what goes in and out of the cell
Mitochondria - where most aerobic respiration happens
Ribosomes - where proteins are made in the cell
Plant Cells contain ...
Cell wall - supports the cell and strengthens it
Permanent vacuole - contains cell sap
Chloroplasts - where photosynthesis happens
