Questions and Answers

What is the difference between asexual and sexual reproduction?

Asexual reproduction involves a single parent and produces genetically identical offspring, while sexual reproduction involves two parents combining gametes to produce genetically unique offspring.

Study Notes

Animal Reproduction

Animals reproduce through asexual or sexual methods, with some capable of both.
Sexual reproduction is complex, involves haploid gametes, and produces genetically unique offspring.
Hermaphrodites or monoecious organisms produce both male and female gametes, often avoiding self-fertilization.

Asexual Reproduction

Asexual reproduction involves a single parent, producing genetically identical clones.
Key characteristics include no fertilization, rapid multiplication, and identical genetic makeup of offspring.
Common types of asexual reproduction:
- Regeneration: Replacement of lost or damaged body parts through tissue production.
- Budding: Formation of a new individual from an outgrowth on the parent, seen in organisms like hydras.
- Parthenogenesis: Development from an unfertilized egg through mitosis, common in species such as aphids and wasps.

Sexual Reproductive Strategies

Some species can change sex during their lifecycle (e.g., clownfish exhibit protandry by transforming from male to female).
Allows adaptation to environmental or social changes.

Animal Nutrition

Essential nutrition for animals includes twelve essential elements and thirteen vitamins important for physiological functions.
Examples of essential elements:
- Calcium is crucial for the formation of bones and teeth.
- Chlorine is involved in forming hydrochloric acid (HCl) in the stomach.
- Copper plays a role in synthesizing melanin and hemoglobin.
