Smallest Unit Of Life

The cell is the smallest unit of life. Organism can be made up of one or more cells. In multicellular organism groups of cells can work together to form tissue. Organs are formed from different tissues and work together with other organs in organs systems. The same kind of organism living together in the same area makes up a population. Different population living together in the same area makes up a community. An ecosystem includes a community and the area’s nonliving parts such as water and soil.

The cell theory states that all organism are made of cells, the cell is the basic unit of life and all cells come from other cells. All cells have a cell membrane, DNA, cytoplasm, and organelles. Most cells are too small to be seen with the naked eye. Materials that cells need to take in or release must pass through the cells membrane. The surface to volume radio is a comparison of the cell’s volume.

A cell’s surface to the cell’s volume ratio decreases as the cell’s grow. Eukaryotes have linear DNA enclosed in a nucleus and membrane covered organelles that are not covered by membranes. All cells have a cell membrane that surrounds the contents of the cells. Some cells have a cell wall outside their membrane. The nucleus is the control center of the eukaryotes cell. It contains the cell’s DNA.

The endoplasmic reticulum and the Golgi complex are membrane covered compartment in which the materials are made and processed before they are transported to other parts of the cell or out the cells.
