|1. The Cell Theory establishes that the cell is the basic unit of life, that all living organisms are composed of cells, and that cells arise from preexisting cells.
2. Plant cells are eukaryotic, having an organized nucleus and membrane-bound organelles.
3. Substances can move into and out of cells by diffusion and osmosis.
4. Mitosis, followed by cytokinesis, results in two genetically identical daughter cells. Growth, replacement of cells, and asexual reproduction all depend on the process of cell division.
