QUESTIONS:
1. What is the difference between asexual and sexual reproduction? Asexual
Reproduction is the reproduction that involves one parent and results in offspring that
is always identical to the parent. Sexual reproduction is the reproduction that involves
two parents and results in offspring that is not identical.
2. TRUE or FALSE: in most cases, in asexual reproduction, the offspring are identical to
the parent. False
3. Describe how the following types of reproduction work. Draw a picture of it
a. Budding
b. regeneration c. runners d. cuttings
A. Budding is when a parent pinches off a part of the organism in order to
form a new organism.
B. Regeneration is when a parent loses a part of the organism in order to form
a new organism.
C. Runners- a type of reproduction in which plants use and reproduce along a
root or vine.
D. Cuttings- a type of reproduction that occurs when a part of a plant is cut off
and planted elsewhere to produce another plant.
4. What is fission? What kind of cells do fission?
Binary fission occurs in prokaryotic (bacteria) cells. Binary fission is when a
prokaryotic cell separates into two or more parts and regenerates these parts
into a different set of cells.
5. Describe the following types of mammal and give an example of each type:
a. Monotreme b. marsupial
c. placental
-Monotreme- a type of sexual reproduction in which eggs are laid and the young
are nourished through the milk of their mother.
- Marsupial- a type of sexual reproduction in which the young is born not fully
developed, but is carried in the mother’s pouch to finish developing.
- Placental- a type of sexual reproduction that most mammals use. The baby is
born fully developed and nourished by its mother.
6. Draw a diagram of MITOSIS. Label each step and describe what is going on
You need to have the full cell cycle of mitosis. Interphase, prophase, metaphase,
anaphase, telophase, and cytokinesis.
7. Draw a diagram of meiosis. Label each step an describe what is going on
Interphase, prophase 1, metaphase 1, anaphase 1, telophase and cytokinesis,
prophase 2, metaphase 2, anaphase 2, telophase 2 and cytokinesis.
8. TRUE or FALSE: the daughter cells in mitosis are exactly identical to the parent cell
True
9. TRUE or FALSE: the daughter cells in meiosis are exactly identical to the parent cell
False
10.
List 3 similarities and 3 differences between mitosis and meiosis
Mitosis:
division of sex cells
half of the amount of chromosomes
results in 2 new cells.
Meiosis:
division of prokaryotic cells
has 46 chromosomes in the nucleus
results in 4 new cells
Similarities:
Both division of cells
Both reproduce cells
Both allow for growth
11.
Why is it OK that the meiosis daughter cells only have half of the needed
chromosomes?
They only have 23 chromosomes because the 46 chromosomes has to be divided
by 2 in order to have half of the maternal chromosomes and half of the paternal
chromosomes.
12.
TRUE or FALSE: mitosis and meiosis are examples of asexual reproduction.
False
13.
TRUE or FALSE: the cells actually split apart during mitosis
False
14.
Identify the following phases of meiosis:
Metaphase 1
Anaphase 2
Telophase 2/cytokinesis
