Identify each type of asexual reproduction below.

What are the differences between asexual
and sexual reproduction?
•Asexual repro uses ONE PARENT while sexual
repro uses TWO PARENTS.
•Asexual repro uses MITOSIS while sexual repro
uses MEIOSIS.
•Asexual repro produces offspring that are
genetically identical to the parent. Sexual repro
produces offspring that are similar but NOT
genetically identical to the parents.
•Sexual repro involves the FERTILIZATION while
asexual repro DOES NOT REQUIRE FERTILIZATION .
What are the differences between mitosis
and meiosis?
•Mitosis produces 2 daughter cells while meiosis
produces 4 daughter cells.
•Mitosis produces daughter cells with the same # of
chromosomes as the parent cell while meiosis
produces daughter cells with the half the # of
chromosomes as the parent cell.
•Mitosis is used for asexual reproduction while
meiosis is used for sexual reproduction.
•Mitosis is used to replicate somatic cells while
meiosis produces gametes (sex cells).

4. What does structure E represent? blastula
5. Which structure forms after the blastula? gastrula
6. Which process occurs after the gastrula? differentiation
1. What is structure A? How was it produced? •zygote
2. Which structures represent cleavage? •fertilization
B, C, D
3. What is structure E? blastula
4. What is structure F? gastrula

differentiation
The development of different organs
and tissues from the embryonic germ
layers is called
(1.) ovulation
(2.) menstruation
(3.) cleavage
(4.) differentiation
1. What kind of fertilization is taking place
above? External fertilization
2. Explain why so many eggs are released
during this process?

Metamorphosis
Cells such as nerve cells and
muscle cells are known as
(1)gametes
(2)sex cells
(3)somatic cells
(4)differentiated cells
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

found in human gametes is
(1) 46
(2) 92
(3) 23

2. binary fission
3. sporulation
4. vegetative propagation
The type of asexual reproduction in which
one cell divides into to two cells that are
of equal size is called
