reproduction & cell division
The life process by which living things produce new living things of the same species is called.............
reproduction
In what Mitosis stage are the chromosomes replicated?
InterPHASE
The last stage of mitosis is called..............
telophase
What is mitosis?
a series of changes in the cell that produces identical daughter cells with exactly the same number and type of chromosomes as the parent cells.
metaphase
The stage of cell division when the chromosomes line up at the cell equator.
What would happen to a species if it stopped reproducing?
The species would vanish
In ______________ the double stranded chromosomes become visible and the nuclear membrane surrounding them disappears
proPHASE
A group of diseases characterized by uncontrolled cell division is called......
cancer
The group of diseases caused by uncontrolled cell division is........
cancer
meiosis
A type of cell division that involves two cell divisions and produces cells that have the haploid number of chromosomes.
Explain why cells must divide
When cells grow to a certain size they must either divide or die. This is because cell growth causes a cell's volume to increase at a faster rate than its surface area. If a cell continued to grow without dividing the surface area would become too small to hold the cell's contents.
During _____________ the centromeres of the double stranded chromosomes become attached to the spindle fibers
metaPHASE
If a species stopped reproducing it would.....
disappear, vanish, be no longer, not exist
Chromosomes are made up of structures called.......
genes
mitosis
A type of cell division that produces identical daughter cells.
The new cells produced by cell division are called?
daughter cells
During ___________ the centromeres replicate and move apart. The two chromatids of each double stranded chromosome move to opposite poles of the cell.
anaPHASE
The normal species chromosome number is called the.....
diploid
Hint:there are five of them
interphase
prophase
metaphase
anaphase
telophase
daughter cells
the new cells form as a result of cell division
The complex series of changes in the nucleus of a cell that leads to the production of two new cells is called.......
cell division
The last stage of mitosis is ____________.
teloPHASE
The type of cell division that produces two identical cells is.....
mitosis
Explain why mitosis is separated into stages.
Separating mitosis into stages makes the process easier to study.
spindle apparatus
Fibers that form between opposite poles of the cell during cell division.
