Study Notes
### Ribosomes
- Ribosomes are non-membranous organelles
- Made up of ribosomal RNA (rRNA) and proteins
- Responsible for protein synthesis
Toluidine Blue
- Toluidine blue is a basic stain
- Used to visualize acidic components, such as nucleic acids (DNA and RNA)
- Turns cells blue due to its affinity for acidic molecules
Mitochondria
- The powerhouse of the cell
- Responsible for producing ATP (adenosine triphosphate) through cellular respiration
- Breaks down glucose to release energy in the form of ATP
Cytoskeleton
- A network of protein filaments
- Provides structural support and shape to the cell
- Involved in intracellular transport and movement of organelles
Melanin
- A pigment found in skin, hair, and eyes
- Responsible for the skin's color
- Produced by melanocytes, cells in the basal layer of the epidermis
- Protects the skin from ultraviolet (UV) radiation
