Question

The mode of nutrition in Rhizopus is:

• A. Saprophytic
• B. Parasitic
• C. Autotrophic
• D. Symbiotic

Answer 1

The correct option is A

Saprophytic

The correct option is A.

Explanation of the correct option:

1. Rhizopus is a member of the Fungi kingdom. It uses a heterotrophic feeding strategy.
2. It is a saprophyte because it consumes the soil's dead and decaying materials.
3. In the dead and decaying materials, the organic compounds are broken down into simpler compounds by the saprophytes.
4. Amino acids are formed from proteins, fatty acids from lipids, glycerol from lipids, and glucose from starch and starch.
5. Endocytosis allows for the re-absorption of these substances into the hypha, where they are distributed throughout the mycelium complex and used for the plant's growth and development.

Explanation of the incorrect option:

Option B:

A parasite is a living thing that inhabits its host and feeds off of or at the expense of it.

Option C:

An organism that can make its nourishment by the use of light, water, carbon dioxide, or other substances is an autotroph.

Option D:

Any of the various coexisting relationships between individuals of two different species, such as mutualism, commensalism, and parasitism, is referred to as symbiosis.

Final answer: The mode of nutrition in Rhizopus is saprophytic.
