Study Notes
Cell Structure and Function
- Cells are the basic units of life and vary in size, shape, and function.
- Cells share common characteristics such as the ability to respond to stimuli, move, and maintain homeostasis.
- The cell membrane, made up of phospholipids, surrounds the cell and controls what enters and exits.
- The cell membrane also contains proteins that act as channels, transporters, receptors, and identity markers.
- The cytoplasm is the gel-like fluid inside the cell that contains organelles, proteins, lipids, carbs, and electrolytes.
- Organelles are structures in the cell that perform specific functions, such as the nucleus, endoplasmic reticulum, ribosomes, Golgi apparatus, lysosomes, centrioles, cilia, flagella, and mitochondria.
- The nucleus is the command center of the cell and contains chromosomes made of DNA and proteins.
- The endoplasmic reticulum is a transportation system in the cell, with smooth ER involved in lipid synthesis and rough ER involved in protein synthesis.
- Ribosomes are responsible for protein synthesis.
- The Golgi apparatus creates and packages vesicles.
- Lysosomes contain digestive enzymes and help clean up the cell.
- Mitochondria are the site of cellular respiration, producing ATP as the energy molecule for the cell.
