meiosis is _____ reproduction,while mitosis is asexual reproduction
sexual
meiosis has __ divisions
2
produces gametes (sperm and egg) while mitosis produces genetically identical cells
meiosis
sex cells divide to produce ___
gametes
the male gametes is__
spermatogenesis
the female gametes is__
oogenesis
gametes have __ the number of chromosomes
half
a fertilized egg is known as
zygote
pair of chromosomes that are similar in shape and size
homologous chromosomes
homologous chromosomes carry__ controlling the same traits
genes
humans have __ of homologous chromosomes
23
the first 22 pairs are known as ___
autosomes
the last pair is known as____
pair of sex chromosomes
having a single set of unpaired chromosomes
haploid
having 2 complete sets of chromosomes,are from each parent
diploid
meiosis has__
sex cells
mitosis has __
body cells
all cells arise from each other cells
cell theory
cell definition
mitosis
type of division results in ___ being produced from one ____
2 identical cells,parent cell
mitosis is ____ reproduction
asexual
asexual reproduction happens with ___ organisms and ____ organisms
single cells,multicellar
mitosis occurs in a series of stages,the stages depend on the type of organism
prokaryotic,eukaryotic
the stages of mitosis begin with ___
one cell (parent cell)
the final product of this type of cell division is___
2 new identical daughter cells
in what phase of the cell cycle do cells spend most of their time?
interphase
list the four phase of mitosis
1.Prophase,2. Metaphase,3.Anaphase, 4.Telophase
(prep) double stranded chromosomes visible-nuclear membrane dissolves.
prophase
the chromosomes move toward the middle of the cell and line up to prepare for division
metaphase
spindle fiber pulls the chromatids apart
anaphase
nuclear membrane reappears around each set of chromosomes forming 2 identical nuclei
telophase
list the advantages of mitosis
quick process makes identical copies
list the disadvantages of mitosis
Slow: it takes two cell divisions.
when it is time to divide,single stranded chromosomes replicate
interphase
splits the cell into 2 cytokenesis
cytokenesis
