Study Notes
Cell Structure
- The cell is the basic unit of life and is comprised of many components working together.
- The plasma membrane acts as a barrier, allowing substances to enter and exit the cell.
- Cytoplasm is a jelly-like substance that fills the cell, containing organelles and providing a medium for cellular reactions.
- The nucleus is the control center of the cell, containing genetic material in the form of DNA.
- Mitochondria are the powerhouses of the cell, responsible for generating energy (ATP) through cellular respiration.
- Ribosomes are responsible for protein synthesis, translating genetic information into proteins.
- The Golgi apparatus processes and packages proteins for secretion from the cell or delivery to other organelles.
- The rough endoplasmic reticulum (ER) is involved in protein synthesis and modification, possessing ribosomes on its surface.
- The smooth endoplasmic reticulum (ER) lacks ribosomes and participates in lipid synthesis, detoxification, and calcium storage.
- Lysosomes are the recycling centers of the cell, breaking down waste materials and cellular debris.
- Microfilaments are thin, thread-like structures that provide support and allow for cell movement.
- Microtubules are larger, hollow tubes that aid in cell shape, movement, and transportation of organelles.
- Centrioles are involved in cell division, helping to organize microtubules during the process.
- Peroxisomes are involved in detoxification and the breakdown of fatty acids.
