Cell theory was given by Schwann, which explains the basic units of living beings. The four main principles of cell theory are:
New cells are made from pre-existing cells.
Cells are basic structural and functional unit of life.
turns light energy from the sun into sugars the cell can use. Function of the cell wall. keeps the cell structure and support. Function of the vacuole. storage of water, salt, proteins, and carbohydrates. Function of the cytoskeleton. forms a framework for the movement of the organelles around the cytoplasm.
3. Virchow- discovered all cells come from preexisting cells
1. cells are the basic unit of life
Function of the mitochondria. converts food into energy. Function of the cell membrane. decides what comes in or out of the cell. Function of the cilia and flagella. builds projections from cell surface and enables the cell to move through a liquid. Function of ribosomes.
D. Cells only come from pre-existing cells. (bio-genesis)
