Pre – AP Biology
Types of Cells and Cell StructuresPart 1
Henri DutrochetCell is the basic unit of life
Theodor SchwannAll animals are composed of cells
Matthias SchleidenAll plants are composed of cells
Rudolf VirchowAll cells come from pre-existing cells
Robert HookeHis simple microscope
Anton von LeeuwenhoekCompound microscope
Anton’s Microscope
Modern Light Microscopes
Microscopic Resolution
Different types of light microscopes
Electron MicroscopeThey can be very large and expensive
Inside an electron microscope
Images from an electron microscopeTransmission (left)/Scanning (right)
Prokaryotic Cell Structure
Eukaryotic Cell (plant)
Eukaryotic Cell (animal)
Surface Area to Volume relationship
Pre – AP Biology
Types of Cells and Cell StructuresPart 2
Nucleus Structure
Chromatin vs. Chromosomes appearance within the cell.
Ribosome Structure
Pre – AP Biology
Types of Cells and Cell StructuresPart 3
Endoplasmic Reticulum
Golgi Apparatus
Lysosomes
Central Vacuole of a plant
Contractile Vacuole of aquatic single celled organismsUsed to get rid of excess water so that the cell does not
burst
Endocytosis
Mitochondrial StructureNotice the two different “spaces”
Chloroplast StructureNotice the two different “spaces”
Lynn Margulis
Endosymbiont Hypothesis
Pre – AP Biology
Types of Cells and Cell StructuresPart 4
Cytoskeleton
Microtubules - Centrioles
Microtubules – Cilia or Flagella
Microfilaments used in various cells for movement
Actin and Myosin in Muscle tissue
Muscle Tissue under the Microscope
Can you see the actin and myosin bands?
Plant cell wall structure
Extra-cellular matrix of animal cells
Cellular junctions helping to make tissues from individual cells
Cells from your lung tissues
Junctions between plant cells
Cells are the sum of it’s partsThey need all parts to function properly
