Animal Form and Function Quiz

Questions and Answers

What is the main difference between asexual and sexual reproduction?

Asexual reproduction involves a single parent producing clones, while sexual reproduction involves two parents combining gametes to create genetically unique offspring.

Which type of reproduction can produce genetically identical offspring?

Asexual reproduction (correct)

Sexual reproduction

Both asexual and sexual reproduction

None of the above

What is a characteristic feature of asexual reproduction?

Involves two parents

No fertilization occurs (correct)

Offspring have varied genetic makeup

Gametes are formed

What are hermaphrodites?

Hermaphrodites are organisms that produce both male and female gametes, allowing them to reproduce sexually. Signup and view all the answers

Study Notes

Animal Reproduction

Animals reproduce either asexually, sexually, or through both methods.
Sexual reproduction involves the combination of haploid gametes, resulting in genetically unique offspring.
Hermaphrodites or monoecious organisms produce both male and female gametes but typically do not self-fertilize.
Asexual reproduction produces offspring from a single parent, resulting in clones with identical genetic makeup.

Types of Asexual Reproduction

Regeneration: New tissues are produced to replace missing or damaged body parts.
Budding: A new individual forms from an outgrowth on the parent's body, observed in hydras and polyps. Buds may break off or remain attached to form colonies.
Parthenogenesis: Development from an unfertilized egg undergoing mitosis without cytokinesis, leading to diploid nuclei that develop like fertilized eggs. Common in species such as aphids and wasps.

Sex Change in Animals

Some organisms can change sex; protandry is when an organism starts as male and becomes female, while protogyny is the reverse.
Example: Clownfish can change from male to female when the dominant female dies, with the largest non-breeding male becoming the new breeding male.

Animal Nutrition

Animals require twelve essential elements and thirteen essential vitamins for proper physiology.
Calcium: Important for bone and teeth structure.
Chlorine: Key in forming hydrochloric acid (HCl) in the stomach.
Copper: Involved in melanin and hemoglobin synthesis.

Description
