Types of Reproduction

Sexual vs. Asexual
Reproduction

Multiple Choice

What type of reproduction takes place when one parent organism produces offspring without meiosis and fertilization?

• pollination

• sexual reproduction

• asexual reproduction

• fertilization

Multiple Choice

All of the following are advantages of asexual reproduction except ____________.

• produce varied offspring

• spread and colonize certain part of an area

• Reproduce without a mate

• produce a large number of offspring

Multiple Choice

Which of the following is a disadvantage of asexual reproduction?

• All organisms have genetic variation

• Parents produces identical off spring which is not suitable for survival in a changing environment

• Finding a mate is not needed

• It can produce a lot of offspring

Multiple Choice

In _________,_____________ only one parent organism produces offspring.

• sexual reproduction

• asexual reproduction

• pollination process

• fertilization process

Sexual Reproduction

❑ A type of reproduction in which the genetic material

from two different cells combine, producing an
offspring

❑ The cells that combine are called sex cells

❑ Female – egg

❑ Male – sperm

❑ Fertilization: an egg cell and a sperm cell join together

❑ A new cell is formed and is called a zygote

Multiple Choice

When egg and sperm combine this process is called

• fertilization

• mitosis

• Meiosis

• cellular respiration

Dropdown

When egg and sperm combine, the resulting cell is called a ​

Select answer

Advantages: Sexual Reproduction

❑ Diverse offspring: genetic variation among offspring

❑ Half of the DNA comes from mom

❑ Half of the DNA comes from dad

❑ Due to genetic variation, individuals within a

population have slight differences

❑ Plants – resist diseases

❑ Traits can develop to resist harsh environments

that allows an organism survive

Can adapt to changing environments

Multiple Choice

What are the advantages of sexual reproduction?

• diverse offspring

• organism can adapt to changing environments

• All are advantages

• None of these are advantages

Disadvantages: Sexual Reproduction

❑ Takes time and Energy

❑

Organisms have to grown and develop until they
are old enough to produce sex cells

❑

Search and find a mate

❑

Searching can expose individuals to predators,
diseases, or harsh environmental conditions

❑

Fertilization cannot take place during pregnancy,
which can last as long as 2 years for some
mammals.

Multiple Choice

How many parents are required for sexual reproduction?

• 1

• 2

Multiple Select

Select all the ADVANTAGE(S) of SEXUAL reproduction

• Produces offspring fast

• Can produce many offspring

• Creates variation in the offspring

• Maintains good traits found in the parents

Multiple Select

Select all the DISADVANTAGES of SEXUAL reproduction

• Maintains all the bad traits seen in the parent

• Reproduction is slow

• Have to find a mate in order to reproduce

• Creates variation in the offspring

Multiple Choice

What is the process called that human cells use to produce egg and sperm cells for sexual reproduction?

• Mitosis

• Meiosis

• Budding

• Binary Fission

Asexual Reproduction

Asexual Reproduction

❑ One parent: organism produces

offspring without fertilization

❑ Uniform offspring:

❑ Because offspring inherit all of their

DNA from one parent, they are
genetically identical to each other
and to their parent

Multiple Choice

When one parent produces offspring that is genetically identical to itself

• sexual reproduction

• asexual reproduction

Binary Fission

❑ Binary Fission: Cell division in prokaryotes that forms two

genetically identical cells – usually prokaryotes

❑ DNA is copied

❑ The cell begins to grow longer, pulling the two copies

apart

❑ The cell membrane pinches inward in the middle of the

cell

❑ Cell splits to form two new uniform, identical offspring

❑ Examples: bacteria, Ecoli, pond critters

Budding: Asexual Reproduction

❑ Budding: a new organism grows by mitosis

and 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

❑ Offspring may remain attached and form

a colony

❑ Examples: Yeast, Hydra, cactus

Regeneration: Asexual Reproduction

❑ Regeneration: occurs when an offspring

grows from a piece of its parent.

❑ Producing new organisms: Sea Stars

❑ Sea urchins, sea cucumber,

sponges, and planarians

❑ Producing new body parts: Gecko

❑ Newts, tadpoles, crabs, hydra,

and zebra fish

Vegetative Propagation: Asexual

❑ Vegetative Propagation: uniform offspring

grow from a part of a parent plant

❑ Parent plants sends out runners

❑ Where the runner touches the ground, roots can

grow

❑ A new plant is produced even if the runner is

broken apart

❑ Each new plant is uniform and identical to the

parent.

❑ Examples: strawberries, potatoes, ivy, crabgrass
