Study Notes
Cell Theory
- Scientists who discovered cell theory are Schleiden, Schwann, and Rudolf Virchow
- The concept of cell theory is that the structural and functional unit of an organism is a cell
- All organisms are made up of one or more cells
- New cells are formed from pre-existing cells
Observed through Light Microscope
-
Animal Cell example: Cheek cell
-
Plant cell example: Onion peel
-
Diagrams show the basic structures of both animal and plant cells.
-
Animal cell has a cell membrane and cytoplasm with a nucleus.
-
Plant cells have similar structures to an animal cell but also include a cell wall, vacuoles, and chloroplasts.
