Study Notes
The Nucleus
- The nucleus contains DNA, essentially the "control center" of the cell.
- The nucleus is surrounded by the nuclear envelope, which allows for the transport of materials into and out of the nucleus.
- Within the nucleus is the nucleolus, which makes ribosomes, essential for protein synthesis.
Cytoplasm
- The cytoplasm is the internal fluid of the cell containing various organelles.
- Cytosol is the fluid portion of the cytoplasm surrounding organelles.
Organelles and their Function
- The rough endoplasmic reticulum (ER) synthesizes membrane lipids and modifies proteins.
- The smooth ER metabolizes lipids and detoxifies the cell.
- Ribosomes are the sites of protein synthesis, utilizing the blueprints encoded in DNA.
- The Golgi apparatus modifies and packages proteins after initial synthesis.
- Mitochondria are responsible for the aerobic (oxidative) phases of cellular respiration, which generate ATP, the cell's energy currency.
- Lysosomes break down waste products.
- Centrioles are involved in chromosome movement during cell division.
- Microtubules provide support and structure for the cell, being part of the cytoskeleton.
- Cilia propel substances across the cell's surface, while microvilli increase surface area for absorption.
The Plasma Membrane
- The plasma membrane is a semipermeable barrier that encloses the cell, regulating the passage of substances in and out.
- Composed of phospholipids and proteins, it effectively creates a controlled environment for cellular processes to occur.
Animal Cell Structure
- The image showcases the internal structures of an animal cell in a three-dimensional view.
- Numerical labels from 1 to 15 are used to identify different parts of the cell.
- Colors are used to differentiate organelles and membranes for visual clarity.
