biology cells specialization quiz
which is true about prokaryotic cells
their genetic material is not contained within a membrane bound nucleus
which is a difference between plant and animal cells
animal cells contain many small vacuoles whereas plants have one large one
cells divide for
growth, repair, reproduction (all of the above)
centromere divides and spindle fibres pull sister chromatids to oppiste poles
anaphase
the spindle fibres allign the chromosomes along the middle of the cell
metaphase
the nucler membrane dissolves, chromatin condenses into chromosomes, centrioles move to opposite piles, and spindle fibres form
prophase
the nuclear membrane reappears, chromosomes decondenses into chromatin, spindle fibres breakdown and the cytoplasm begins to divide
telophase
dna decondensed chormatin, wrap around to form DNAs condensed chromosomes
histones
which stage of the cell does DNA replicate
interphase
what is the product of the somatic cell cucle
two genetically identical cells
which of the following types of transport refers to the movement of water from an area of low concentration to an area of hugh concentration
