chp 10 cell cycle
how many stamens does the flower have
6
if a cell has 12 chromosomes, how many do each of it's daughter cells have after mitosis
12
the phase of interphase where dna replication takes place, organelles are duplicated
S phase
which does not belong with the others: stigma, anther, style, ovule, ovary
anther
a single parent or one cell where the cell makes a copy of dna and organelles and then divides
asexual reproduction
centrioles break apart and move to opposite poles in the cell during prophase and form
asters
a mother cell divides into two unequal parts, both have the capability to carry out a further division, this type of reproduction is known as
budding
the outer whorl of the flower is the
calyx
a disorder in which body cells lose the ability to control growth
cancer
in telophase of plant cells, the cell is divided by the cell wall simply cutting the cell in half due to the rigidity of the cell wall this
cell plate
animal cells have these and are used in cell reproduction
centrioles
the center point of a chromatid is the __________ which is where spindle fibers attach to each sister chromatid
centromere
a doubled up chromosone
chromatid
at the beginning of cell division, a chromosome consists of two
chromatids
in eukaryotes, dna and proteins combine to form
chromatin
in prokaryotes, most cells have a single _________ that contains all the genetic material
chromosome
in telophase of animal cells, the cell is divided by the cytoplasm pinching inward dividing the two new daughter cells, this is known as
cleavage furrow
what regulates the timing of the cell cycle in eukaryotes
cyclin/growth factors
the division of cells into two equal parts is
cytokensis
what is not a phase of mitosis
cytokinesis
developing stage of a multicellular organism from which the adult organism is produced
embryo
which of the following is not an advantage of asexual reproduction
increases genetic diversity
a cell is 92% to 95% in this phase
interphase
the cell cycle is divided into two stages __________ and cell divison
interphase
the period between cell divisions is called
interphase
the cell cycle in a eukaryotic cell is divided into
interphase, mitosis, and cytokinesis
most serious form of skin cancer
melanoma
in this phase all the chromatids line up in the middle
metaphase
which phase of mitosis do the chromatids line up at the equator
metaphase
the division of the nucleus is
mitosis
which of the following is not an advantage of asexual reproduction
no genetic diversity
which no sexual structure of the flower comes in a variety of shape, size, anther, color, and pattern
petals
what two structures represent the sex organs of a flower
pistil and stamen
which of the following is not an example of asexual reproduction
seed production
what makes up the outer whorl of the flower
sepal and petal
whats the purpose of the flower
sexual reproduction
which type of reproduction gives you genetic diversity by a recombination of genes
sexual reproduction
asters shoot out protein filaments that attach themselves to the centromere of the chromatids these are
spindle fibers
when Mendel crossed the parent plants it was the pollen from the tall plant to the egg of the short plant, which order: pistil to stamen, stamen to pistil, filament to anther
stamen to pistil
once the seeds mature, what becomes of the ovary
stigma
the phase of mitosis in which the cleavage furrow forms
telophase
mass of rapidly dividing cells that can damage surrounding tissue
tumor
which material is important for a cell to remove
waste
layers or parts of flowers are known as
whorls
the first phase of interphase known as the gap phase where the cell is growing and doing its normal activities
G1 phase
the shortest phase of interphase when the cell is about to divide
G2 phase
chromatids pull apart and move to opposite sides
anaphase
