8.
Describe 3
differences
between
mitosis and
meiosis.
• Mitosis
• Meiosis
- Asexual
- Same # of
chromosomes as
the parent cell
- One division
- Used to
reproduce body
cells (somatic
cells)
- Sexual
- Half the # of
chromosomes as
parent cell
- Two divisions
- Used to produce
gametes (sex cells)
Let’s summarize…
1. Describe the two types of cells that
our bodies consist of.
2. Explain the difference between
asexual and sexual reproduction.

1. What process is represented in the diagram?
2. Describe the genetic makeup of daughter
cells.
3. What does phase A represent? What occurs
in this phase?
4. Explain what is occurring at phase E.
What is the name of the process
that produces gametes?
(1) Mitosis
(2) Binary fission
(3) Asexual reproduction
(4) Meiosis
Cells such as nerve cells and
muscle cells reproduce by the
process of
(1) meiosis
(2) mitosis
(3) binary fission
(4) budding
Which statement is true about sexual
reproduction?
1. It produces offspring with half the
number of chromosomes as the
parent.
2. It involves sex cells joining together.
3. It produces offspring that are
genetically identical to the parents.
The result of meiosis are daughter cells
that have
1. half the number of chromosomes
2. a quarter of the number of
chromosomes
3. double the number of chromosomes
4. the same number of chromosomes
The number of chromosomes
found in human gametes is
(1) 46
(2) 92
(3) 23
