Th Cell as the Basic Unit of Life
Like cement sets the foundation for a house, the cell theory sets the foundation for biology. Schleiden and Schwann proposed the cell theory, which states that the cell is the basic unit of life and that new cells arise only from the reproduction of already existing cells via cell cycle, in 1839. Since the cell is the structural and functional unit of life as the house is for a community, without the house the community

Cell Reproduction
CELL REPRODUCTION DNA is the cell's genetic material; chromosomes are the carriers of this genetic information. In proka-ryotes, the chromosome is a single circle of DNA. In eukaryotes, each chromosome is a complex of DNA and histone proteins found in the nucleus. BINARY FISSION Prokaryotic cells reproduce via binary fission. In this process, DNA Is replicated, and the cell splits in two roughly equal parts, each with a copy of the cell's DNA. EUKARYOTIC CELL

The Cell Membrane in Cells
This can be seen in living cells. The cell membrane in cells is semi-permeable and the vacuole contains a sugar/salt solution. So when a cell is placed in distilled water (high water concentration) water will move across the semi-permeable membrane into the cell (lower water concentration) by osmosis, making the cell swell. This cell is now referred to as turgid. If done with potato cells the cells would increase in length volume and mass
