Q

mitochondria

A

produce ATP energy

17
Q

centrioles

A

pull chromosomes apart during mitosis

18
Q

cytoskeleton

A

provides structure and increases mobility/surface area

19
Q

mitosis

A

cell division that produces diploid somatic cells w/ 2 sets chromosomes

20
Q

meiosis

A

cell division produces haploid gametes w/ single set chromosomes

21
Q

interphase

A

cell prepares for division by replicating DNA and doubling in size

22
Q

prophase

A

chromatin condenses to chromosome and centrioles project spindle fibers, envelope/nucleotides disappear

23
Q

metaphase

A

chromosomes attach by centromeres at equator and held by spindle fibers

24
Q

anaphase

A

chromatids separate into chromosomes and sets pulled to opp sides

25
Q

telophase

A

cytokinesis and development of nuc envelope forms around chromosomes (decondense)

26
Q

cytokinesis

A

division of cytoplasm during telokinesis
