1) Hooke, Leeuwenhoek, Schgleiden, Schwann and Virchow contributed to the cell theory.
2) The compound microscope was invented in the late 1500s, then leeuwenhoek’s single-lens micriscope was an improvement. The microscope was improved through the century and a half, where it could magnify much better.
3) All living things are made up of cells.
4) All cells are produced by previously existing cells.
5) Cells are the basic unit of living things.
6) The cell theory states that the cell is the basic unit of all organisms, and cells are produced by previously existing cells.
7) Eukaryotic cell
12) Cell membrane
All cells have:
16) Cell membrane
17) Microscopic proportions
1) The cytoskeleton gives shape and support to the cell.
2) A human skeleton also gives shape and support.
3) The cytoskeleton keeps its shape together like human muscles keep its skeleton connected.
4) Stores/protects DNA, and has it readily available.
6) Conduct protein synthesis
7) Process, sort, package, store, and deliever proteins
9) Use chemical reactions to supply energy to the cell
10) Stores water, food molecules, inorganic ions, and enzymes
11) Contain enzymes and protects from invading bacteria and viruses. They digest and recycle foreign materials.
12) Organize microtubules to form flagella and cilia
13) Cell walls can support the shape of an entire plant; even a mighty tree made up of dead cell walls can stand.
14) Both animal and plant cells have cell membranes, while only plants have cell walls. Cell walls give shape and support while cell membranes form a boundary from it’s outside environment.
15) Chloroplasts conduct photosynthesis, and without that plants wouldn’t have energy, and there’d be no life on Earth because plants couldn’t live.
16) Endoplasmic Reticulum (ER)
