A Selectively Permeable (Semi-Permeable) Membrane Divides a Vessel in Half
Different amounts of solute and water are on either side of the membrane. The membrane is not permeable to the solute.
3 Statements of the Cell Theory
- All organisms are composed of one or more cells
- The cell is the basic unit of life in all living things
- Cells are produced by the division of pre-existing cells
The cell theory is of tremendous importance to humanity. It has contributed to the development of vaccines, cures for diseases, and advancements in medical research. Understanding the cell theory helps define life itself.
Cell Membrane: A Mosaic Art
The cell membrane is often compared to mosaic art due to their similarities. Both are an array of many different pieces stuck together. The cell membrane contains various components such as mitochondria, ribosomes, and lysosomes, which are all interconnected like a mosaic. This analogy highlights the complexity and interconnectedness of the cell membrane.
