Cell Anatomy
Question | Answer |
---|---|
3 Parts of a Cell | Nucleus; Cytoplasm; Cell Membrane |
Nuclear Membrane | Envelope around Nucleus (blue) |
Nucleolus | Bodies inside the nuclear membrane (white) |
Chromatin | Hairy type stuff inside the nuclear membrane (red/brown color) |
Organelles | Structures within the cytosol that perform specific functions within the cell. (fruit cocktail) |
Mitochondria | Cheeto type structure (orange) Produce 95% of ATP required by the cell. |
Golgi Body | Thin stacks of flattened membranes containing chambers (red) |
Golgi Vesicles | Circle that extend from golgi body (secretory vesicles) (red circles) |
Lysosome | Vesicles containing digestive enzymes (purple bumps) |
Fat Vacuole | Where food is stored (peroxisomes) (yellow bumps) |
Rough Endoplasmic Reticulum | Network of membranous channels extending throughout the cytoplasm (blue sacks with red dots) contains ribosomes |
Smooth Endoplasmic Reticulum | Blue Sacks without ribosomes |
Ribosomes | RNA + proteins; can be attached to endoplasmic reticulum or scattered in cytoplasm (red) |
Centrioles | Migrate - leads to division of cells (pink/white cylinders) |
Mitosis | Division of the nucleus |
List the 4 Phases of Mitoses | Prophase; Metaphase; Anaphase; Telophase |
What happens during Prophase? | Beginning of Mitosis. Centrols migrate to opposite poles. Spindle fibers are formed. Nuclear Membrane disappears. |
What happens during Interphase? | Cell looks normal. Has nucleus in center. |
What happens during Metaphase? | Chromatids move to center. |
What happens during Anaphase? | Take on "V" shape. |
What happens during Telophase? | Spindle fibers disappear. Daughter Cells. Nuclear membranes re-appear |
