Worksheet time: 2hrs 20mins

Name
Class
Date
1.
Which statement best describes the process of asexual reproduction?
a)
new organisms are usually genetically identical to the parent
b)
the reproductive cycle involves the production of games
c)
nuclei of sex cells fuse to form a zygote
d)
it involves the production of genetic copies 
2.
In asexual reproduction, all of the offspring are:
a)
Physically Identical
b)
Genetically Identical
c)
Physically and Genetically Identical
d)
Not Identical
3.
A hydra reproduces when an outgrowth, or bud, forms and continues to develop until if falls off of the parent. This is an example of:
a)
Binary Fission
b)
Sporulation
c)
Budding
d)
Vegetative Propagation
4.
a)
budding
b)
sporulation
c)
vegetative propagation
d)
binary fission
5.
This is when a new organism grows by cell division on the body of its parent. The bud, or offspring is identical to the parent. The bud, when large enough, can break off of the parent and live on its own.  Examples of this include yeast, hydra and potatoes.
 
a)
Regeneration
b)
Vegetative propagation
c)
Fission
d)
Budding
6.
a)
budding
b)
binary fission
c)
sporulation
d)
regeneration
7.
What type of asexual reproduction is taking place?
Fishermen work hard to catch and remove all the starfish that get into their favorite shell fishing beds and the “underwater farms” where they raise clams and oysters. In the past, they put the starfish into their boats, cut them up with knives, and then throw the pieces of starfish overboard. They thought this would kill the starfish. What they did not know was that each piece of starfish will grow into a whole new animal.
a)
Regeneration
b)
Vegetative propagation
c)
Budding
d)
Fission
8.
How many parent(s)are needed for asexual?
a)
4
b)
1

100
9.
When a starfish grows a new body off a broken arm, what kind of reproduction is this?
a)
Sexual
b)

10.
What are some of the facts about asexual reproduction?
a)
Takes only one mate to reproduce and takes a longer time to reproduce
b)
Takes a shorter amount of time to reproduce and it takes two mates to reproduce
c)
Reproduces diverse offspring and takes a longer time to reproduce
d)
Takes only one mate to reproduce and takes a shorter time to reproduce
11.
This produces 2 identical cells.
a)
mitosis
b)
meiosis
12.

reproduces asexually

13.

a)

Sexual reproduction

b)

Asexual reproduction

14.

Reproducing asexually will produce offspring ...

a)

15.
What is a disadvantage of asexual reproduction?
a)
New species of organisms cannot come into being.
b)
The offspring does not multiply rapidly.
c)
The offspring does not live for long.
d)
All of these
16.
Prokaryotes reproduce asexually through -
a)
Spore formation
b)
Vegetative propagation
c)
Binary fission
17.
In general, asexual reproduction is used by _______ organisms.
a)
simple
b)
extinct
c)
complex
18.
