Asexual Reproduction

• A means "without" or "not"

  Occurs when organisms make more of itself (identical)

• Practiced by most single-celled organisms including bacteria, archaebacteria, and protists. Some plants, animals, and fungi can reproduce asexually.

Types of Asexual Reproduction

• Binary Fission

• Budding

• Spores

• Fragmentation

• Vegetative reproduction

Advantages of Asexual Reproduction

• Rapid population growth

• No mate needed

• Fewer resources needed

Disadvantage of Asexual Reproduction

• Lack of diversity

Multiple Choice

How does the DNA of the offspring formed from asexual reproduction compare to the parent?

• none of the DNA is transferred to the offspring

• half of the DNA is transferred to the offspring

• the DNA of the offspring is identical to the DNA of the parent

• none of these are correct

Multiple Choice

Which of these is NOT an advantage of asexual reproduction.

• Enables organisms to reproduce without a mate

• Requires less time and energy

• Results in little genetic variation

• Enables organisms to produce large amounts of offspring

• Enables plants to spread and colonize an area in a short period of time

Multiple Choice

All of the offspring of an organism have the same genetic material, which is identical to the parent organism?

• makes its own food
• goes away
• live in a marine habitat
• reproduces asexually

Multiple Choice

If the environment changes for an Asexual offspring it will?

• Explode
• Create another offspring
• Fall in love
• Die

Did you know???

Some species of plants, animals, and fungi are capable of both depending on the environment!

Sexual Reproduction

• Occurs in some fungi, some protists, and many plants and animals.

• Uniting of different gametes, which are reproductive cells

• Genetic information from both parents

• Offspring gets 23 chromosomes from each parent

Advantages of Sexual Reproduction

• Increased diversity

• Genetic variation

• Survival advantage

Disadvantage of Sexual Reproduction

• Time is needed to find a mate

• Isolation cannot happen in order to mate

Multiple Choice

Why does sexual reproduction result in more genetic diversity than asexual reproduction? 

• Traits from two parents are combined. 
• More organisms reproduce this way. 
• Offspring grow in different environments. 
• Offspring come from identical parents. 

Multiple Choice

What are some of the facts about sexual reproduction?

• Takes two mates to reproduce and takes a longer time to reproduce

• Takes one mate to reproduce and takes a shorter amount of time to reproduce

• Takes two mates to reproduce and takes a shorter amount of time to reproduce

Multiple Choice

Male and female reproductive cells are collectively known as:

• spores

• pollen

• gametes

• offspring

Multiple Select

What are some disadvantages to sexual reproduction? (select all that apply)

• it takes a lot of energy to find a mate

• you don't need another mate

• it requires a male and a female

• more genetic errors can occur
