    Study Notes

    Endoplasmic Reticulum

    • Rough endoplasmic reticulum is involved in protein synthesis
    • The presence of ribosomes attached to the surface of rough endoplasmic reticulum gives it a basophilic appearance in the cytoplasm
    • Smooth endoplasmic reticulum is present in cells that are involved in lipid synthesis and metabolism, such as liver cells and adipocytes

    Mitochondria

    • The primary function of mitochondria is to generate energy for the cell through cellular respiration
    • Janus green B stain can be used to visualize mitochondria by light microscopy
