Study Notes
Cell Structure and Function
- The smallest structural and functional unit of an organism is a cell.
Microscope Development
- Antonie van Leeuwenhoek is credited with developing the microscope lens to see greater magnification.
Prokaryotic vs Eukaryotic Cells
- The main difference between prokaryotic and eukaryotic cells is the presence of a membrane-bound nucleus containing DNA in eukaryotic cells.
Cell Discovery
- Robert Hooke is credited with discovering cells and calling them "cellulae" (Latin for "small rooms").
- Matthias Schleiden concluded that plants are composed of cells.
- Theodor Schwann concluded that animals are composed of cells.
Cellular Observations
- Anton van Leeuwenhoek observed and described single-celled animals like protozoa and bacteria.
- Robert Hooke observed and described cell walls in cork tissue under a microscope.
Cellular Characteristics
- Cells are the basic unit of matter and are involved in homeostasis.
- All cells come from the division of previous existing cells, as proposed by Rudolph Virchow.
- All organisms are composed of cells.
Cell Components
- Chloroplasts are organelles found in cells, not a gel-like substance.
Note: I corrected the mistake about chloroplasts being a gel-like substance.
