Studied by 1 personNucleus
Site where the chromatin is located
Chromatin
Combination of DNA and histone proteins
Nucleus envelope
Phospholipid bilayer surrounding the nucleus
Nucleolus
Area of condensed chromatin. Site where ribosomes are produced.
Ribosome
Site of intracellular protein synthesis.
Rough Endoplasmic Reticulum
Site of extracellular protein synthesis. Composed of folded membranes covered in ribosomes.
Smooth ER
Site where lipids are produced. Also helps clean (detoxify) the cell. No ribosomes here
Cytosol
The liquid of the cell that the organelles are found in
Golgi complex
Site of protein modification and packaging for extracellular shipment
Lysosome
Site of intracellular digestion. Contains hydrolytic enzymes.
Vacuole
Site of water storage in plants. Fills with water for more structural support.
Mitochondria
Site of aerobic respiration and ATP production
Chloroplast
Carbohydrate producing organelle. Site of photosynthesis.
Peroxisome
-turns toxins into hydrogen peroxide of H2O2 Contains the enzyme catalase which turns H2O2 into water
Cytockeleton
Used for cellular structure and support includes microtubules > intermediate filaments > microfilaments
Cytoplasm
Everything outside of the nucleus but still within the cell.
Plasa membrane
Phospholipid bilayer surrounding the cell. Is selectively permeable.
Light Microscope (Compound Microscope)
light passes through a specimen producing an enlarged image of the object of the specimen -the lenses bend the light so the image of the specimen is magnified
Electron Microscope
focuses a beam of electrons through the specimen or onto its surface -distinguishes biological structures as small as 2 nm
Transmission Electron Microscope (TEM)
used to see 2-D image of internal structures
Scanning Electron Microscope (SEM)
used to see the 3-D image of a surface
Coarse Focus Knob
Fine Focus Knob
Objective Lenses
Condenser
focuses light through the specimen
Iris Diaphragm
controls the amount of light passing through the specimen
