100
Interphase, Mitosis and Cytokinesis.
What are the three stages of cell cycle?
100
These are the three forms of asexual reproduction.
What are binary fission, budding and regeneration.
200
Before a cell divides, the DNA becomes wrapped around proteins and then is further compacted into structures called ______.
What are CHROMOSOMES
200
Organisms that are made up of only one cell are called _______
What is UNICELLULAR
200
This is the stage of mitosis where the chromosomes form.
What is PROPHASE.
200
TRUE or FALSE: At the end of cell cycle, the daughter cells are genetically the same as the parent cell.
What is True. At the end of cell cycle, the parent cell splits into two genetically identical daughter cells.
200
Forms of bacteria use this form of asexual reproduction.
What is binary fission.

In plant and animal cells, DNA is contained in the ______.
What is NUCLEUS
300
Single celled organisms that do not have a nucleus.
What are prokaryotes
300
This is the part of mitosis where two new nuclei begin to form.
What is TELOPHASE

300
Bread yeast use this form of asexual reproduction.
What is budding.
400
The shape of DNA is called a ______
What is DOUBLE HELIX (or twisted ladder)
400
The four roles of cell division.
What are growth, development, repair and reproduction.
400
These are the structures during anaphase that pull chromosomes to opposite sides of the cell.
What are spindle fibers.
400
An activity or set of events that repeat.
What is a cycle?
400
These are two differences of asexual reproduction compared to sexual reproduction.
Provide at least two: Asexual reproduction requires one parent, the rate of reproduction is faster, offspring are genetically identical to the parent.
