Question

One of the following does not reproduce by spore formation method:

• A. Rhizopus Fungus
• B. Penicillium Fungus
• C. Yeast Fungus
• D. Mucor Fungus

Answer 1

The correct option is C

Yeast Fungus

The correct option is C.

Explanation of the correct option:

1. The tiny single-celled, thin-walled, or thick-walled entities known as spores are produced when sporangia break.
2. Spores are used to carry out asexual reproduction.
3. A single-celled creature called yeast reproduces by budding.
4. Asexual reproduction is in the form of budding.
5. On the parent organism's body, a little bulb-like projection known as the bud grows during budding.
6. The bud keeps expanding on the parent plant until it transforms into a tiny adult.
7. When the bud reaches full maturity, it pinches off from the parent's body and develops the capacity to function autonomously.

Explanation of the incorrect options:

Option A:

1. A fungus genus called Rhizopus has both saprophytic and parasitic species.
2. They are present in organic foods such as fruits, vegetables, bread, jams, jellies, and bread.
3. As sporangiospores are created inside a spherical structure called the sporangium, they can replicate both asexually and sexually through the creation of spores.

Option B:

1. The term "green mould" or "blue mould" refers to a particular form of fungus called Penicillium.
2. Oil globules are used for food storage.
3. Endogenous sexual spores are represented by ascospores.
4. Asexual spores produced exogenously are represented by conidiophores.

Option C:

1. A typical filamentous fungus called Mucor can be found in plants, decaying and dead animals, fruits, and vegetables.
2. It is frequently employed as a lab contaminant as well.
3. As erect sporangiophores develop, Mucor reproduces asexually.

Final answer: Yeast fungus does not reproduce by spore formation method.
