Unit 6-10 Science Review

Organisms that reproduce asexually generally have offspring that are genetically

• similar

• identical

• different

• close

Why does sexual reproduction result in genetically diverse offspring?

• traits from one parent is combined

• more organisms reproduce this way

• traits from two parents are combined

• offspring grow in different environments

A plant that has traits that are identical to the parent plant was most likely created by

• asexual reproduction

• sexual reproduction

• pollination

• photosynthesis

What is a major benefit of sexual reproduction?

• The offspring grow faster

• Time and energy is used to find a mate

• DNA will be less varied and more stable

• increased genetic diversity

Tags

NGSS.MS-LS4-4

What advantage do the offspring of sexual reproduction

most likely have as a result of fertilization?

• Unfavorable traits will be eliminated

• The offspring grows faster

• DNA variation may allow for survival in a changing environment

• Traits will be perfectly adapted to the environment

What would happen if mitosis did NOT take place?

• Organisms would be single celled

• Chromosomes would not divide in half

• The production of gametes would not occur

• pollination would not exist

Bacteria reproduce through

• binary fission

• pollination

• vegetative propagation

• budding

asexual reproduction involves

• 3 parents

• no parents

• 2 parents

• 1 parent

NGSS.MS-LS1-4

A major benefit of asexual reproduction

• it increases genetic diversity

• it increases the survival chances in a changing environment

• organisms can reproduce hundreds of times in an hour

• it is very slow

What is the result of mitosis?

• 2 nuclei that are similar

• 4 nuclei with half the number of chromosomes

• 2 identical nuclei

• 4 nuclei that are similar
