Study Notes
Cell Structure
- Different substances that make up a cell are collectively called protoplasm.
- Protoplasm is composed of:
- Water (70-80%)
- Carbohydrates
- Lipids
- Proteins
- Electrolytes (Sodium (Na+), Potassium (K+), Magnesium (Mg2+), Calcium (Ca2+), Phosphate, Chloride (Cl-), and Bicarbonate (HCO3-))
Subcellular Structures
-
Key structures present in a cell include:
- Cell membrane
- Cytoplasm and its organelles
- Nucleus
-
DNA: Contains coded information inherited by every single cell.
-
Nucleus: The control center of the cell.
-
Endoplasmic reticulum: Smooth and rough tubes that move and store materials.
-
Lysosome: Site of cell nutrient digestion.
-
Cytoplasm: Jelly-like fluid surrounding the nucleus containing all organelles.
-
Cell membrane: A double layer of fatty material allowing materials into and out of the cell.
-
Mitochondrion: Produces energy by breaking down substances.
-
Golgi complex: Collects, packages, and distributes molecules.
-
Ribosome: Protein-producing factories.
-
Vacuole: Storage area for fats and other substances.
-
Peroxisome: Vesicle with enzymes to detoxify harmful substances.
-
Centriole: Involved in cell division.
