Total questions: 25
Worksheet time: 28mins
Cells spend most of their lives in which phase?
Interphase
Prophase
Telophase
Metaphase
What is cytokinesis?
When 2 cells merge together to make 1 giant cell
The end of the cell cycle when the cell divides and mitosis is complete
The stage when DNA condenses into chromosomes
The stage where chromosomes are pulled to opposite ends of the cell.
Why do cells go through mitosis?
to make food from sunlight
to get air into the cells
to create proteins
to reproduce, grow, and repair/replace cells
How many chromosomes does a human somatic (body) cell have?
46
23
42
26
How many chromosomes does a human egg or sperm (gamete) cell have?
23
46
42
26
Daughter cells created by meiosis II have
half the parents DNA
exact copy of the parent's DNA
twice the parent's DNA
created their own DNA from scratch
What is "crossing over"?
The exchange of genes between chromosomes during meiosis that results in genetic diversity.
Programmed cell death (cell suicide) to prevent the spread of mutated/cancerous cells.
A type of cell division that creates gametes (sperm and egg cells).
A type of cell division that results in two daughter cells each having the same number of chromosomes as the parent cell.
What is a difference between mitosis and meiosis? Mark ALL that apply!
Mitosis occurs in the cytoplasm and Meiosis occurs in the nucleus.
Mitosis results in diploid (2n) daughter cells and Meiosis results in haploid (n) daughter cells.
Mitosis results in 2 daughter cells and Meiosis results in 4 daughter cells.
Mitosis makes somatic (body) cells and Meiosis makes gametes (egg and sperm cells).
What is cancer?
A polypeptide
Regular cell growth
Controlled cell division
Unregulated cell growth and division
If a regular body cell has 50 chromosome, how many would a Haploid cell from Meiosis would have?
100
5
50
25
What is the purpose of Meiosis?
To heal, grow and replace cells
To produce two identical daughter cells
To produce cancer
To produce gametes for sexual reproduction
Meiosis is responsible for:
Staying the same
Similar cells
Creating identical cells
Genetic Diversity
In Meiosis, the chromosomes go through crossing over, this leads to:
Genetic variation
Identical daughter cells
To replication of genes
No me acuerdo sir
What are sex cells from Meiosis called?
Somatic
Gametes
Diploid
None of the above
Skin, hair and nails are a product of:
Meiosis
Mitosis
Both
Daughter cells created by mitosis have
half of the parents genetic material
twice the parent cell's genetic material
an exact copy of the parent cell
have a brand new DNA structure
