Questions and Answers
What is asexual reproduction?
Asexual reproduction is a process where offspring are produced from a single parent without the fusion of gametes.
Describe the process of budding in Hydra.
In budding, a parent Hydra develops bulges on its body that eventually detach to form new independent individuals.
What observations can be made about the bulges on a parent Hydra during budding?
The bulges may vary in size and number, indicating different stages of development.
Do gametes and a zygote form in asexual reproduction? Why or why not?

Study Notes
Modes of Reproduction in Animals
- Two primary modes of reproduction in animals: Sexual and Asexual.
Asexual Reproduction
- Definition: Offspring produced from a single parent without gamete fusion.
- Organisms like amoeba, paramoecium, and hydra can reproduce asexually.
- Offspring often develop from bulges called buds that form on the parent organism.
Example: Budding in Hydra
- Budding is a common method of asexual reproduction observed in Hydra.
- Parent Hydra develops bulges (buds) that eventually detach to form new individuals.
Observation of Budding in Hydra
- Use a microscope to examine different stages of budding in Hydra through permanent slides.
- Look for bulges on the parent body and observe variations in their sizes.
- Compare diagrams from different slides to track development stages.
Key Questions
- Change Observation: Identify the difference between the first two slides and the next two slides.
- Bulge Development: The swollen bulge on Hydra develops into a new independent Hydra.
- Gametes and Zygote Formation: No gametes or zygote are formed during asexual reproduction, as it does not involve fusion of reproductive cells.
