Question

A yeast cell differs from a bacterial cell as it is

• A. Eukaryotic
• B. Multicellular
• C. Unicellular
• D. Prokaryotic

Answer 1

The correct option is A

Eukaryotic

The correct option is A.

Explanation of the correct option:

1. Eukaryotes include protists, fungi, plants and animals.
2. Yeast is an example of a fungus.
3. It is a unicellular and eukaryotic organism.
4. It reproduces asexually by budding.
5. They have their DNA present in the nucleus.
6. They have a heterotrophic mode of nutrition.

Explanation of the incorrect options:

Option B:

1. A multicellular organism is an organism composed of many cells.
2. They are eukaryotic.
3. They have a well-defined nucleus and membrane-bound organelles.

Option C:

1. The organisms which are made up of single cells are called unicellular organisms.
2. They can be eukaryotes and prokaryotes.
3. They reproduce asexually.
4. Nutrition is done by osmosis or diffusion for smaller particles and pinocytosis and phagocytosis for larger particles.

Option D:

1. Prokaryotic cells are represented by bacteria, blue-green algae, and mycoplasma.
2. They do not have a well-defined nucleus.
3. DNA is not enveloped by the nucleus membrane.
4. Many bacteria have small circular DNA apart from the genomic DNA.
5. They do not have organelles, unlike bacteria.
6. They have a specialised differentiated form of the cell membrane called mesosome which is essentially the infolding of the cell membrane.

Final answer: A yeast cell differs from a bacterial cell as it is eukaryotic.
