Understand the Problem
The image presents a set of short-answer questions related to biology, specifically focusing on the topics of reproduction and fertilization. The questions require defining key terms and providing examples.
Answer
1. Fertilization: fusion of gametes to form a zygote. 2. Metamorphosis: abrupt change in body structure. 3. Sexual reproduction: reproduction involving two parents, e.g., dogs and cats. 4. Asexual reproduction: reproduction involving one parent, e.g., starfish and some bees. 5. Sperm: male gamete; function is to fertilize the egg.
Here are the answers to the questions:
- Fertilization is the process of combining the male and female gametes to form a zygote.
- Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.
- Sexual reproduction is a type of reproduction that involves two parents contributing genetic material to produce offspring. Examples include dogs and cats.
- Asexual reproduction is a type of reproduction that involves only one parent and produces offspring that are genetically identical to the parent. Examples include starfish and some species of bees.
- A sperm is a male gamete that carries the male's genetic information to the egg during fertilization. The function of a sperm is to fertilize the egg, initiating the development of a new organism.

More Information
There are different types of asexual reproduction, including budding, fragmentation, and parthenogenesis.
Tips
It is important to understand the difference between sexual and asexual reproduction. Sexual reproduction involves two parents and results in genetically diverse offspring, while asexual reproduction involves one parent and results in genetically identical offspring.
