1. CELLULAR GROWTH/MATURATION
2. CELL DIVISION

22
Q

attainment of normal size
assembly of the necessary organelles
accumulation of sufficient energy
storage of essential materials

A

CELLULAR GROWTH AND MATURATION

23
Q

chromosomes and cytoplasmic
components systematically and
equally divide into two daughter
cells

A

CELL DIVISION

24
Q

includes all the important processes in
cellular reproduction

A

CELL DIVISION

25
Q

cell division in ________is through
________

A

PROKARYOTE BINARY FISSION

26
Q

____resultant DNA molecules attach to
different cell membrane to divide the
cytoplasm and its chromosomes into two
identical daughter cells

27
Q

cell division in _______cells undergo the
repeating sequence summarized as follows:

Stage 1: G1 (Gap 1) Phase
Stage 2: S (Synthesis) Phase
Stage 3: G2 (Gap 2) Phase
Stage 4: M (Mitosis/Meiosis) Phase

28
Q

longest phase in most cells

cell undergoes rapid growth until it
attains normal size

formation of organelles

enzymes needed for S phase are
produced

29
Q

DNA is duplicated
each chromosome is made up of two
sister chromatids by the end of this
stage

30
Q

preparations for cell division
assembly of microtubules causes the
chromosomes to move during cell
division

31
Q

cell undergoes division
karyokinesis - division of nucleus
cytokinesis - division of cytoplasm

32
Q

division of nucleus

A

KARYOKINESIS

33
Q

division of cytoplasm

A

CYTOKINESIS

34
Q

is a type of cell division in which
the nucleus of the cell divides into two
nuclei with identical genetic material

35
Q

1 diploid parent =

A

2 diploid daughter cells

36
Q

occurs in eukaryotes

37
Q

promotes growth, development, tissue
repair, and asexual reproduction

38
Q

what are 4 stages of mitosis

A

PROPHASE
METAPHASE
ANAPHASE
TELOPHASE

39
Q

chromatins coil as individual
chromosomes
each chromosome contains two
identical sister chromatids from
DNA replication
centrioles migrate to opposite poles
nucleolus disappears

40
Q

chromosomes align at the center of
the cell (metaphase plate)
spindle fibers connect each sister
chromatids to the centrioles via the
kinetochore

41
Q

spindle fibers shorten to pull the
two sister chromatids apart toward
them

42
Q

sister chromatids are at the
opposite poles
new nuclear membrane forms
around the chromosomes
spindle fibers dissolve

43
Q

After the telophase, _________and ________ will occur.

A

CYTOKINESIS AND KARYOKINESIS

44
Q

inward
pinching of the cell membrane until the
cell divides

A

CLEAVAGE FURROW FORMATION

45
Q

division starts
at the middle and moves outward

A
