Cell Division in Eukaryotic Cells Quiz
What happens to the DNA by the end of the S phase of interphase
DNA replicates
cellular organs BEGIN to duplicate
G1 phase
What are the sub phases of interphase
G1 phase, S phase, G2 phase
cell growth and protein synthesis
G2 phase
We can this divide the cell cycle into
Interphase and mitotic phase
DNA replication happens meaning chromosomes are doubled
S-phase
where are the only parts where plants can increase their lengths
at the tips of most roots, stems, branches, and buds
the ---- includes all of the events in the life of an individual cell, from cell division to the period when a cell is not dividing while it carries out its regular functions
cell cycle
in the plant cell cytokeneis is accomplished by the formation of a partition or ---- ----
cell plate
before cell division two pairs of protein bodies called ---- are present in the cytoplasm at one end of the cell
centrioles
the sister chromatids are attached in a region known as the ------
centromere
In interphase, the nucleus contains darkly stained ----
chromatin
a term that applies to all of the chromosomes (DNA) collectively
chromatin
distinct rod shaped bodies of chromatin
chromosomes
the autumn crocus contains a chemical called ---- which depolymerazies the protiens in the mitotic spindle
colcheline
also known as cytoplasmic division. This includes the formation of cleavage furrow in animal cells and a partition called the cell plate in plant cells during telophase of cell division
cytokinesis
what phase is the formation of the cell plate
cytokinesis
what phase is the formation of the cleavage furrow?
cytokinesis
in mitosis parent cells divides into two identical ----- -------
daughter cells
in the plant cell cytokeneis is accomplished by the formation of a partition or cell plate between the the two now formed ------ ---------
daughter nuclei
In metaphase the chromosomes become arranged in the central region of the cell known as the
equator
what type of cells do we observe in mitosis in todays lab
eukaryotic cells
period of cycle when cell is not dividing
interphase
---- ---- are the parts of plants where cell division actively occurs
meristematic regions or meristems
in metaphase the chromosomes become arranged in the central region of the cell known as the equator. We call this as the formation of the ------ -----
metaphase plate
this is also known as nuclear division. This includes prophase, metaphase, anaphase, and telophase
mitosis
what phase is when a parent or mother cell divides into two identical daughter cells that have the same number of chromosomes as the parent cell.
mitosis
Period of cell division
mitotic phase
is the cell actively dividing in interphase?
no
a ------ is clearly visible inside the nucleus in interphase
nucleolus
in this phase the nuclear membrane and nucleolus begin to disintegrate and the chromatin shortens and thickens so they are distinct rod shaped bodies.
prophase
what does the nucleolus contain
ribosomal DNA
each chromosome is doubled and consists of two identical -------- --------
sister chromatids
in metaphas, protein threads called the ---- ---- connect the centromeres regions of each chromes with the centrioles at the poles of the cells
spindle fibers
where can you find plant meristems
they are at the tips of most roots, stems, branches, and buds
What does the chromosomes look like in interphase
they are threadlike and are not visible
what do we observe to observe plant cells during the different stages of the cell cycle. So what did we observe in the activity
tips of young onion roots also known as Alliums
true or false centrioles are not typically present in plant cells?
true
true or false. In order to observe plant cells during mitosis, we have to observe a part of a plant that is actively dividing
true
two chemicals --- and ---- from the madagascar periwinkle are also potent in spindle poisons
vinblastine and vincristine
in the lab activity how do we observe mitosis?
we observe prepared slides of organisms (or parts of organisms) that were actively dividing
