Vocabulary
a series of events in which a cell grows, prepares for division and divides to form two daughter cells.
What is the Cell Cycle?
True or False. Interphase is the longest stage in the cell cycle.
True
What are the 4 phases of mitosis?
prophase, metaphase, anaphase, telophase
Cytokinesis begins at about the same time as ________________.
telophase
The cell makes a copy of its DNA in its nucleus before cell division
What is replication?
DNA replication results in the formation of threadlike structures called _____________________.
chromosomes
Briefly describe prophase.
In prophase DNA condenses into separate chromosomes.
During cytokinesis in animal cells, the cell membrane squeezes together around the middle of the cell. True or False
True
Define the interphase stage.
the first stage of the cell cycle that takes place before cell division occurs during which a cell grows and makes a copy of its DNA
Each chromosome inside the nucleus of the cell contains two identical sets of DNA, called ___________.
chromatids
Briefly describe metaphase.
In metaphase, chromosomes line up in center of a cell.
A plant cell's rigid cell wall cannot squeeze together in the same way that a cell membrane can. True or False
True.
Define the stage of mitosis.
What is the second stage of the cell cycle? The cell divides into two new nuclei and one set of DNA is distributed into each daughter cell.
In animal cells, not plant cells, a pair of _________ is duplicated. These help later with dividing the DNA between the daughter cells.
centrioles
Briefly describe anaphase.
In anaphase, chromatids pulled to separate sides.
Describe how cytokinesis in plant cells is different from cytokinesis in animal cells.
Plant cells form a cell plate between the two daughter cells. Then cell membranes and cell walls grow around the new cells.
Define the stage of cytokinesis.
the final stage of the cell cycle in which the cells cytoplasm divides distributing the organelles into each of the two new daughter cells.
Briefly describe telophase
In telophase, nuclear membrane forms around separated chromatids/DNA.
