Cell Division
As a cell grows larger, this cannot keep up with the demands of the cell
What is DNA?
These three phases are collectively known as interphase
Mitosis is the division of this
What is the nucleus?
Cytokinesis is the division of this
What is the cytoplasm?
These are the genetic structures inside the nucleus that are duplicated
If the cell grows too large, it will have trouble moving enough of these 2 things across the cell membrane
What are nutrients and waste?
During G1, the cell does this
What is grows/increases in size?
The chromosomes condense and the spindles form during this phase
What is prophase?
At the end of mitosis this many nuclei have been formed
What is 2?
Chromosomes are contained in this
What is the nucleus?
The number of cells that are formed from one round of cell division
What is 2?
During S phase, this happens to DNA
What is the replication/duplication?
The nuclear membrane begins to form and the cell begins to pinch in during this phase of mitosis
What is telophase?
The chromosomes in each nucleus are this to each other
What is identical?
When chromosomes condense, they are now called these
What are chromatids?
A cell is more effective when its surface area to volume ratio is ...
What is high/large?
During G2 phase, the cell assembles these
What are special structures for division/spindles?
The chromosomes line up in the center of the cell during this phase of mitosis
What is metaphase?
In animal cells, the cell membrane pinches in and forms this
What is a cleavage furrow?
What is a centromere?
The size of a cell is limited by this ratio
What is surface area to volume ratio?
Interphase accounts for this percentage of the cell cycle
What is 90%?
The spindles shorten and pull apart the chromatids during this phase of mitosis
What is anaphase?
In plants, the rigid cell wall prevents the cell from pinching inward, instead this happens
What is a cell plate forms midway?
This organelle forms spindles that pull apart the chromatids
What is centrioles?
