3
Asexual reproduction is...

Making offspring that are genetically unique
Making offspring genetically identical
Making more offspring then needed
4
Vegetative reproduction is an example of
asexual reproduction
stamen
cross pollination
binary fission
5
budding
starfish
yeast
offspring grows by mitotic division on the body of its parent
potato and strawberry
6
The following is not a form of asexual reproduction :
budding
spore formation
gamete production
binary fission
7
Cloning produces identical individuals from a cell(s) taken from a unicellular organism.
True
False
8
How is regeneration a form of asexual reproduction?
When a body part is lost it can grow a new one
When cut in half it will grow half its body
When cut in half it will grow back vital organs
When cut in half it will grow two new organisms
9
Some animals have been cloned using the cytoplasm from a cell in one parent.
False
True
10
Offspring growing from a piece of its parent
fission
budding
regeneration
tissue culture
11
Which of these is one of the advantages of Asexual Reproduction?
Does not usually require as much energy
Very few offspring are usually created
It can use one or two parents
Creates genetic diversity
12
Offspring growing on the body of its parent
tissue culture
budding
regeneration
fission
13
One parent producing offspring without meiosis and fertilzation.
asexual reproduction
Cloning
sexual reproduction
budding
14
A major disadvantage of asexual reproduction is
if the adult is well adapted then so will be the offspring
many offspring can be produced quickly
offspring identical to parent, so can be wiped out if environment changes
favourable conditions can be taken advantage of quickly
15
___ is a type of asexual reproduction developed by scientists and performed in laboratories.
Cell Division
Cloning
Bacteria
Fission
16
Why is genetic variation so important?
for a population be able to adapt to a changing environment
populations adapt better with the same genetic make-up
it's not important
17
Which of these is one of the advantages of Asexual Reproduction?
Creates genetic diversity
Requires a lot of energy
Only one parent is required
Very few offspring are usually created
18

There are downsides to cloning
True
False
20
____ are changes in genetic material (DNA), that can be passed to offspring and affect their ability to survive.
Biology
Variations
Genes
Mutations

Asexual reproduction by plants is called
regeneration
vegetative reproduction
budding
cloning

Prokaryotic cell division is called ____.
vegetative reproduction
fission
budding
regeneration
23
Some plants can be cloned with just a few cells using a technique called?
nuclues division
budding
fission

2 cells with the same # of chromosomes as the parent cell
4 cells with ½ the # of chromosomes as the parent cell
1 cell with the same # of chromosomes as the parent cell
25
Explain regeneration
Limbs use bianary fission to fuze together
a new organism grows from a piece of its parent
Lizards
Starfish
26
Which is the correct definition of Vegetative Reproduction?
When the seed grows into a new plant
Offspring grow from a part of a parent plant
I have no idea
