A student scraped his knee while playing tennis. He noticed that after two weeks his wound had nearly healed with just a small scar remaining. Which statement BEST explains the healing process?
The cells near the wound divided to form new cells.
The cells from distant areas moved in to cover the injured part.
The cells near the wound grew in size to cover the injured part.
The cells released materials that covered the wound and repaired the cells.
Why is the formation of new cells important?
It allows for growth, repair and reproduction.
It allows unicellular organisms to carry out all life activities.
It creates enzymes that regulate all chemical reactions.
It creates large unicellular organisms from prokaryotic cells.
Which term best describes the process that increases the quantity of cells?
locomotion
nutrition
mitosis
respiration
Buddind and binary fission are both forms of asexual reproduction in one-celled organisms. What is known about the daughter cells produced as a result of the two processes?
Mitosis ensures that they are identical to one another and to the original parent cell.
Mitosis ensures that they have half the genetic information from the original parent cell.
Respiration ensures that they are identical to one another and to the original parent cell.
Respiration ensures that they have half the genetic information from the original parent cell.
How is the process of mitosis essential to the survival of an organism?
It creates new daughter cells to replace the parent cells.
It prevents accumulation of waste in cells.
It ensures proper storage of nutrients in cells.
It provides the required amount of energy to cells.
Which of the following CORRECTLY describes the events of each phase of mitosis?
1. formation of cell plate
2. condensation of chromosomes
3. movement of sister chromatids to opposite ends of the cell.
4. attachment of spindle fibers on centromere.

3. attachment of spindle fibers on centromere.
4. condensation of chromosomes
None of these are correct.
A teacher described the importance of three cellular processes that are essential for the survival of an organism:
1. It enables the cell to make a copy of itself.
2. It enables the cell to release energy for cellular activities.
3. It enables the cell to store energy in the form of sugars.

What would likely happen if a multicellular organism no longer performed mitosis?
The organism would generate new cells only by the process of meiosis.
The organism would rely on gaining cells fro m other nearby organisms.
The organism would adapt to function without the use of cells.
The organism would die as it is no longer able to replace damaged cells.
How confident are you that you know what the phases of mitosis look like and can put them in order?
I am VERY confident!
I am confident
I need more practice.
What in the world is mitosis?
A cell becomes injured and can no longer carry out mitosis. Which statement describes the most immediate effect on the cell?
It would be more susceptible to disease.
It would accumulate harmful toxins and waste.
It would be unable to break down sugars for energy.
It would be unable to divide into new cells preventing growth.
Which processes are responsible for cell growth and reproduction?
mitosis and meiosis
mitosis and osmosis
meiosis and photosynthesis
osmosis and photosynthesis
A student reads a passage about passing information from one generation to the next.
1. In humans, an egg combines with a sperm to create a new individual.
2. The offspring created has exactly the same number of chromosomes as the parent which is 46 chromosomes or 23 pairs.
What can the student conclude about the number of chromosomes in sex cells (egg and sperm)?
Sex cells have one fourth the number of chromosomes as the parent cell.
Sex cells have one half the number of chromosomes as the parent cell.
Sex cells have the same number of chromosomes as the parent cell.
Sex cells have double the number of chromosomes as the parent cell.
Which statement accurately describes how genetic information is transferred during meiosis?
Meiosis creates four daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates two daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates four daughter cells that have identical genetic information to the parent cells.
Meiosis creates two daughter cells that have identical genetic information to the parent cells.
A fertilized egg receives 50% of it's chromosomes from a sperm and 50% from the egg. Which process ensures that the sperm and egg contain only 50% of the chromosomes of an organism?
fertilization
mitosis
meiosis
mutation
Complete the statement to accurately describe how genetic information is transferred during meiosis.
Meiosis creates ____________ that have ________________ .
two daughter cells, identical genetic information to the parent cell
two daughter cells, half the number of chromosomes that are present in the parent cell
four daughter cells, identical genetic information to the parent cell
four daughter cells, half the number of chromosomes that are present in the parent cell
The diagram shows a parent cell undergoing the process of mitosis.
A student claims that mitosis can be a form of asexual reproduction and writes several statements.
1. Daughter cells inherit genes from only one parent cell.
2. Daughter cells are identical copies of a parent cell.
3. Daughter cells have more genetic content than the parent cell.
Which statement(s) can the student provide to support the claim?
1 only
2 only
1 and 2
1 and 3
Domestic cats transfer their genetic information to their offspring by meiosis. If a kitten has 38 chromosomes, how many chromosomes does the kitten inherit from its mother?
12
19
30
38
The diagram shows the process of mitosis. What is the purpose of this process?
It helps the cell function efficiently.
It helps the cell form energy molecules.
It helps the cell make an exact copy of itself.
It helps the cell increase its genetic material.
The image shows a wound in the epidrmal tissue of the human skin. The epidermal tissue next to the wound undergoes mitosis to help in the healing process.
Which property of mitosis is the most useful in the healing process?
Mitosis causes a cell to undergo uncontrolled division.
Mitosis produces new cells that are identical to the parent cell.
Mitosis allows a cell to divide into four cells each with double the size of the parent cell.
Mitosis ensures that each newly produced cell has more genetic material than the parent cell.
