LFRollins Asexual vs Sexual Reproduction

Which statement correctly describes a difference between sexual and asexual reproduction?

• Sexual reproduction only happens in animals, while asexual reproduction only happens in plants.

• Sexual reproduction requires fertilization of one gamete by another gamete, while asexual reproduction requires only one parent to produce an offspring.

• Sexual reproduction only happens in single-celled organisms, while asexual reproduction only happens in multicellular organisms.

• Sexual reproduction only happens when cells have a nucleus, while asexual reproduction only happens when cells do not have a nucleus.

The diagrams represent the way three different organisms reproduce. Which of these classifies the reproductive method of all the organisms shown?

• Segmentation

• Budding

• Asexual reproduction

• Sexual reproduction

In some types of plants, breaking off a single part of a plant can create a new plant. This new plant is genetically identical to the original plant. This is an example of...

• An adaptation

• A mutation

• Sexual reproduction

• Asexual reproduction

During which process does genetic material come from two parents?

• Asexual reproduction

• Photosynthesis

• Respiration

• Sexual reproduction

During sexual reproduction, a sperm cell fertilizes an egg cell to form a fertilized egg. The fertilized egg then develops into a new organism. Which statement describes the primary advantage of sexual reproduction over asexual reproduction?

• Sexual reproduction produces identical offspring.

•  Sexual reproduction results in less adaptable offspring.

• Sexual reproduction generates a large number of offspring.

• Sexual reproduction results in genetic variation in offspring.

Paramecia usually reproduce asexually. Fish reproduce sexually. Suppose the environmental conditions in the lagoon change. What advantage will the fish population have over the paramecium population?

• Sexual reproduction produces offspring that are identical to the parents.

• Sexual reproduction decreases the genetic variability in the fish population.

• Sexual reproduction limits the spread of harmful characteristics in fish populations.

• Sexual reproduction allows populations to adapt to new conditions over fewer generations.

Which of the following is true of asexual reproduction?

• It requires seeds.

• It requires flowers.

• It requires only one parent.

• It requires sperm and eggs.

Creates the greatest diversity, and therefore the ability to survive changing environments.

• Cloning

• Sexual reproduction

• Asexual reproduction

• Fragmentation

Which is a disadvantage of asexual reproduction?

• Lack of diversity in offspring

• Offspring share strengths of parents

• Population can grow quickly

• No energy  spent finding a mate

Sexual reproduction requires which of the following to occur?

• Budding

• Binary Fission

• Gametes

• Fragmentation
