How do the offspring of asexual and sexual reproduction compare to their parents?
Asexual reproduction produces offspring identical to parents. Sexual reproduction produces offspring that are genetically diverse.
100
What type of reproduction is mitosis?
Asexual reproduction
100
What type of cells does meiosis produce?
Sex cells (egg + sperm)
100
What type of reproduction is shown in the image below? How do you know?
Asexual because there is only one parent.
100
List an advantage of asexual reproduction
- Fast
- little energy needed
- lots of organisms can be produced

A student is trying to decide the type of reproduction a particular organism undergoes. She notices that all the offspring are identical to the parents. What type of reproduction is this?
Asexual reproduction because the offspring are identical
200
A carrot cell has 30 chromosomes. After undergoing mitosis, how many chromosomes do the new carrot cells have?
30 because mitosis results in the same number of chromosomes as the parents.
200
What two types of cells are necessary for sexual reproduction?
Egg and sperm cells
200
What type of reproduction is being shown in the image?
Asexual reproduction because there is only one plant parent
200
how are the phases of Meiosis different from the phases of mitosis?
In meiosis, the PMAT phases happen TWICE
300
What is the main advantage of sexual reproduction compared to asexual reproduction?
More genetic variety in the offspring
300
List the phases of mitosis in order (hint: PMAT)
Prophase, Metaphase, Anaphase, Telophase
300
A carrot has 30 chromosomes. After undergoing meiosis, how many chromosomes do each of the offspring cells have?
15, because in meiosis the offspring have half the number of chromosomes as the parent
300
What type of reproduction is shown in the diagram below? How do you know?
Sexual because there are sex cells (eggs)
300
A dog has 76 chromosomes. How many chromosomes do the daughter cells have after meiosis?
38! Half!
400
Why do the offspring of sexual reproduction have greater genetic diversity?
Because they have genetic information from two gametes (parents)
400
Explain what is happening during this phase of mitosis
The chromosomes are lining up in the middle of the cell and the spindles are attached to the middle. This is metaphase.
400
What happens in prophase 1 of meiosis that doesn't happen in mitosis?
Crossing over, which is where genetic information gets shared.
400
What process is being shown in the image below?
Meiosis because the offspring have half the number of chromosomes as the parent.
400
Give THREE ways you could know if an organism reproduces asexually.
- Offspring are identical to the parent
- FAST rate of reproduction
- Something that affects the parent will also affect the offspring
500
Broadcast spawning is where fish gather together and release sperm and eggs into the water for fertilization. This type of reproduction is a form of?
Sexual reproduction because it involves sex cells (egg and sperm)
500
Tell the CORRECT order of these mitosis phases based on the pictures
B - Prophase, A - Metaphase, D - Anaphase, C - Telophase
500
List TWO disadvantages to sexual reproduction
- Takes more time
- Takes more energy
500
What phase comes next in this process of mitosis? What happens in that phase?
Telophase. In telophase, the nucleus reforms, the chromosomes de-condense, and the cell begins to the split.

Pick two phases of mitosis and accurately name and describe what happens in each.
Varies
