Study Notes
Golgi's Contributions
- Developed the ‘black reaction’, a staining method for highlighting individual nerve and cell structures.
- Utilizes a weak silver nitrate solution, crucial for tracing delicate cell processes and ramifications.
- Continuously improved this staining technique throughout his life.
- Awarded numerous honors, including sharing the 1906 Nobel Prize with Santiago Ramony Cajal for work on the nervous system's structure.
Lysosomes
- Membrane-bound sacs filled with digestive enzymes produced by the rough endoplasmic reticulum (RER).
- Function as the cell's waste disposal system, digesting foreign materials and worn-out organelles.
- Break down complex substances into simpler ones using powerful digestive enzymes.
- Can burst during cellular metabolism disturbances, leading to self-digestion, which labels them the ‘suicide bags’ of the cell.
Mitochondria
- Referred to as the powerhouses of the cell due to their role in energy production.
- Comprise two membranes, with the outer being porous and the inner deeply folded to increase surface area for ATP generation.
- Produce ATP (Adenosine triphosphate), the cell's energy currency, essential for chemical activities and mechanical work.
- Unique for containing their own DNA and ribosomes, allowing them to synthesize some proteins independently.
Vacuoles
- Primarily found in plant cells, filled with cell sap to provide turgidity and rigidity.
- Store essential substances like amino acids, sugars, organic acids, and proteins.
- In single-celled organisms like Amoeba, food vacuoles store consumed food items.
- Specialized vacuoles in some unicellular organisms help expel excess water and waste.
Plastids
- Exclusively present in plant cells, classified into two types: chromoplasts (colored) and leucoplasts (colorless).
