Unit 9(Animal Reproduction) and Unit 10 (Plant Reproduction)

Which statement reflects a way in which asexual reproduction is beneficial? Select all that apply.

• It results in genetic variation.

• It requires a lot of time and energy.

• Organisms can reproduce without a mate.

• It is a much quicker process.

Where does an offspring get its DNA in asexual reproduction?

• from both parents

• from only one parent

• from neither parent

What is an advantage of sexual reproduction?

• Allows genetic variation
• Only needs one parent
• Happens very quickly
• Offspring are exact copies of parent

When a starfish grows a new body off a broken arm, what kind of reproduction is this?

• Sexual
• Differentiation
• Asexual 
• Specialization

Baker’s yeast is a tiny, single-celled fungus that makes bread dough rise and converts sugars in alcohol. This yeast reproduces by budding. As the small bud grows, it receives a copy of the parent’s nucleus. When the bud pinches off, the new cell is smaller than the parent cell but genetically identical  What type of reproduction is this?

• Asexual
• Sexual

Redwood trees are the tallest and largest trees in the world. Like other conifer trees, the trees bear male and female cones that rely on the wind for pollination. What kind of reproduction is this?

• Asexual
• Sexual

When comparing the offspring of sexually and asexually reproducing organisms, we would expect the genetic material (DNA) of the sexually reproducing organism to -

• contain fewer mutations
• be lesser in quantity
• be simpler overall
• show more variation

What are some of the facts about asexual reproduction?

• Takes only one mate to reproduce and takes a longer time to reproduce
• Takes a shorter amount of time to reproduce and it takes two mates to reproduce
• Reproduces diverse offspring and takes a longer time to reproduce
• Takes only one mate to reproduce and takes a shorter time to reproduce

All of the offspring of an organism have the same genetic material, which is identical to the parent organism. From this, we can conclude that this organism -

• makes its own food
• is unicellular
• is likely to be a plant
• reproduces asexually

If two organisms reproduce sexually, then their offspring will exhibit a genetic makeup that is -

• identical to only one parent
• identical to all of its siblings
• a unique combination of traits
• the recessive traits of each parent
