Study Notes
Tissue Preparation for Microscopy
- Dehydration is the procedure immediately preceding clearing a specimen with an organic solvent in tissue preparation for light microscopy.
Basic Living Unit
- The cell is the basic living unit of all plants and animals.
Study of Tissues
- Histology is the study of tissues.
Mitochondria's Vital Product
- ATP (Adenosine Triphosphate) is the vital product of mitochondria.
Microscope Structures
- The body tube connects the eyepiece to the objective lens.
- An electron microscope does not depend on visible light.
- Sectioning is the step after tissue is embedded in paraffin.
- Hematoxylin stains structures blue or purple.
Organelles and Cellular Structures
- Ribosomes
- Lysosomes
- Golgi apparatus
- Cristae (folds on the inner mitochondrial membrane)
- Mitochondria (powerhouse of the cell)
- Endoplasmic reticulum (not an inclusion)
- Smooth endoplasmic reticulum (involved in lipid metabolism)
- Cytoplasm (fluid inside the cell)
- Plasma membrane
- Endocytosis
- Rough endoplasmic reticulum (produces protein for export)
- Nucleolus (where ribosomes are assembled)
- Phagocytosis (transport of solid particles)
- Peptidoglycan (not part of the plasma membrane)
- Peroxisomes (contain detoxifying enzymes)
- Glycocalyx (polysaccharide on outer surface of cell membranes)
- Ribosomes (site of protein synthesis)
- Cytoskeleton
- Microtubules
- Nucleus (where ribosomal subunits are formed)
Additional Cellular Processes and Structures
- Telophase (last phase of mitosis)
- Eukaryotes (organisms with nuclei surrounded by nuclear membranes)
- Rough endoplasmic reticulum and smooth endoplasmic reticulum (most developed in liver cells)
- Lysosomes (contain digestive enzymes)
