Cellular Organelles and Functions

Mitochondria is the organelle responsible for cellular respiration.
The cell membrane, also known as the plasma membrane, regulates what enters and leaves the cell, maintaining cellular homeostasis and protecting the cell from external damage.
The cytoskeleton provides structural support, shape, and mechanical stability to the cell, and is involved in cell division, transportation of organelles and molecules, and cell signaling.
