What is cell division?
The process by which a parent cell divides into two or more daughter cells.
The process by which a cell moves from one location to another.
The process by which a cell changes its shape and size.
The process by which a cell combines with another cell to form a larger cell.
What is mitosis?
Mitosis is a process of DNA replication.
Mitosis is a process of cell differentiation.
Mitosis is a process of cell death.
Mitosis is a process of cell division.
What is DNA replication?
The process of transcribing DNA into protein.
The process of combining DNA from two different organisms.
The process of copying a DNA molecule to produce two identical DNA molecules.
The process of creating RNA molecules from DNA.
What is asexual reproduction?
Asexual reproduction is the process by which an organism produces offspring that are genetically identical to itself.
Asexual reproduction is the process by which an organism produces offspring that are a combination of genetic material from two parents.
Asexual reproduction is the process by which an organism produces offspring through the fusion of gametes.
Asexual reproduction is the process by which an organism produces offspring that are genetically different from itself.
What are the advantages of asexual reproduction?
Higher genetic diversity, ability to adapt to changing environments, and increased chances of survival in unpredictable conditions.
Faster reproduction, no need for a mate, and ability to produce offspring in stable environments.
What is cell growth?
Increase in size and number of cells in an organism
Decrease in size and number of cells in an organism.
The process of cell division.
The process of cell death.
What is the purpose of DNA replication?
To produce RNA molecules for protein synthesis.
To repair damaged DNA.
To create genetic diversity in offspring.
To ensure each new cell receives an identical copy of genetic information.
What is a chromosomes?
Packaged DNA
Powerhouse of the cell
A cell
When a skin cell with 20 chromosomes divides by mitosis cell division, the resulting daughter cells will each normally have how many chromosomes?
10
20
40
80
What happens when your fall and scrape your knee?
Skin cells divide by mitosis to produce new cells that are exact copies.
Skin cells divide by mitosis to produce new cells that are different from each other
Which of the following is NOT a reason for BODY CELLS to go through cell division?
Growth
Repair
Replace dead cells
Creation of sex cells
Bacteria populations can increase very quickly, this is do to how bacteria cells reproduce.
sexual reproduction
asexual reproduction
A parent cell contains 12 chromosomes. In preparation for cell division the parent cell replicates the DNA. Before division, how many chromosomes are in the parent cell?
6
12
24
48
Mitosis produces how many cells?
2 identical cells
4 identical cells
cells are not identical
What is cell differentiation?
Stem cells become specialized making an organism complex with different cell types.
Different cells become stem cells
