Worked Solution & Example Answer:Draw a diagram of Rhizopus - Leaving Cert Biology - Question c - 2015
Step 1
Draw a diagram of Rhizopus. Label a rhizoid, a sporangium and a stolon on the diagram.
Answer
To draw a diagram of Rhizopus, start by illustrating the main structure of the fungus. Include the following components:
- Rhizoid: These are root-like structures that anchor the Rhizopus to the substrate.
- Sporangium: This is the spore case where spores are produced. It can be depicted as a round structure at the end of a stalk.
- Stolon: This is a horizontal stem that connects different parts of the fungus.
Make sure to clearly label these components on your diagram.
Step 2
Step 3
Explain the importance of this type of nutrition in nature.
Answer
Saprophytic nutrition is crucial in nature as it helps in the breakdown of dead organic matter. This process recycles nutrients back into the ecosystem, making them available for other organisms. It plays a vital role in maintaining soil fertility and supporting plant growth.
Step 4
Step 5
Name one economically harmful member and one economically beneficial member of the kingdom to which Rhizopus belongs.
Answer
An economically harmful member of the Fungi kingdom is rusts, which can damage crops. A beneficial member is yeast, which is used in baking and fermentation processes, as well as penicillium, which is involved in cheese production.
Step 6
In Rhizopus, which type of reproduction results in the formation of a zygospore?
Answer
The type of reproduction in Rhizopus that results in the formation of a zygospore is sexual reproduction. This occurs when two compatible strains come together to form a zygospore during the reproductive phase.
