Study Notes
Cell Biology Basics
- The basic unit of life is the cell.
Cell Membrane
- The cell membrane, also known as the plasma membrane, is a thin layer that separates the cell from its environment and regulates the movement of materials in and out of the cell.
Cytoplasm
- Cytoplasm is the jelly-like fluid that fills the inside of the cell, where many metabolic processes take place.
Organelles
- Organelles are structures that perform specific jobs inside the cells.
Types of Cells
- All organisms belonging to the animal kingdom have animal cells.
- Nerve cells (neurons) are the longest cells in the human body.
Mitochondria
- Mitochondria are the organelles responsible for energy production in animal cells through cellular aerobic respiration.
Golgi Apparatus
- The main function of the Golgi apparatus in an animal cell is to process and modify proteins and lipids synthesized by the endoplasmic reticulum.
Nucleus
- The nucleus is responsible for storing genetic information in the form of DNA.
Plasma Membrane Composition
- The plasma membrane is composed of a phospholipid bilayer with proteins and cholesterol embedded in it.
Ribosomes
- Ribosomes are responsible for protein synthesis in a cell.
Cytoplasm Function
- The cytoplasm plays a crucial role in maintaining the cell's internal environment, providing a site for metabolic reactions, and supporting the cell's structural framework.
Animal Cells vs. Plant Cells
- Animal cells are distinguished from plant cells by the absence of a cell wall and chloroplasts.
Lysosomes
- The main function of lysosomes in a cell is to break down and recycle cellular waste, foreign substances, and damaged cellular components.
