All About Cells
Cell: A cell is the basic structural and functional unit of all living organisms. Cells are made up of a membrane, cytoplasm, and genetic material. Organelles: These are the parts of a cell that help with its function. Examples of organelles are the nucleus, mitochondria, and ribosomes. Cell Membrane: This is a thin flexible barrier that surrounds the cell and holds it together. It also helps regulate what enters and leaves the cell.
Cells have their own internal clocks that can tell time, even without any external cues. Cells can actually 'listen' to their environment to sense changes in the environment. Cells communicate with one another through a process called quorum sensing.
