Question | Answer |
---|---|
what’s the main site of ATP synthesis | mitochondrion |
what encloses the chromatin | nucleus |
which part of the cell is the sac of digestive enzymes | lysosome |
examples of ____ include glycogen granules and ingested foreign materials | inclusion |
this part of the cell forms basal bodies and helps direct motorists spindle formation | cytoskeleton |
site of protein synthesis | ribosome |
forms the external boundary of the cell | plasma membrane |
site of lipid synthesis | smooth er |
packing site for ribosomes | nucleolus |
this part of the cell is responsible for packing proteins for transportation | golgi apparatus |
internal cellular network of rodlike structures | centriole |
what is the function of mitotic cell division | where one cell becomes two identical cells |
what is interphase? | normal activities |
early prophase | chromatin condenses |
late prophase | nuclear envelope breaks up |
metaphase | centrosomes are at opposite ends of the cell. chromosomes line up in middle |
anaphase | chromosomes pull to opposite poles |
telophase | identical sets of chromosomes at opposite poles. cell starts to split |
cytokinesis | ring of actin microfilaments form a cleavage furrow and pinches cell apart |
given that antibodies are made by proteins, which membrane-enclosed cell organelle would you expect plasma cells to have in abundance? | ribosomes |
which organelle would you expect to play the biggest role in cell decomposition | lysosomes |
where in the cell cycle would medication halt a cell with fungus? | late interphase or prophase. it would prevent the infected cell from replication |
referred to as mitosis | division of the nucleus |
division of cytoplasm | cytokinesis |
different between chromatin and chromosomes | chromosomes coil, condense, and shorten |
chromosomes attach to spindle fibers by undivided structures | centromeres |
cell undergoes mitosis but not cytokinesis | binuclear cell |
acts as scaffolding for chromosomal attachment and movement | spindle |
period of life when cell isn’t in division | interphase |
cell populations that don’t undergo cell division | neurons, skeletal muscle cells, cardiac muscle cells |
