GPT-4o mini
All cells, whether prokaryotic or eukaryotic, share common structural and functional components. The five parts common to all cells are:
1. **Cell Membrane**: A phospholipid bilayer that surrounds the cell, providing structure and regulating the movement of substances in and out of the cell.
2. **Cytoplasm**: The jelly-like substance within the cell membrane that contains all the cell's organelles and is the site of many metabolic processes.
3. **Ribosomes**: Molecular machines that synthesize proteins by translating messenger RNA (mRNA). Ribosomes can be found floating freely in the cytoplasm or attached to the endoplasmic reticulum.
4. **Genetic Material (DNA/RNA)**: The hereditary material that contains the instructions for the cell's functions and activities. In prokaryotes, DNA is usually found in a single circular chromosome, while in eukaryotes, it is organized into multiple linear chromosomes within the nucleus.
5. **Cytoskeleton**: A network of protein filaments and tubules that provide structural support, shape, and the ability to move. The cytoskeleton also plays a role in intracellular transport.
These basic components are essential for the life and function of all cells.
