Question

Identify the correct statement:

• A. Tissue is a group of dissimilar cells.
• B. An organ consists of similar cells.
• C. Vacuoles are not found in plant cells.
• D. Prokaryotes do not have nucleus.

Answer 1

The correct option is D

Prokaryotes do not have nucleus.

The correct option is D.

Explanation of the correct option:

1. The nucleoid is an irregularly shaped area of a prokaryotic cell that contains all or most of the genetic material, known as the genophore.
2. It is not enclosed by a nuclear membrane, unlike the nucleus of a eukaryotic cell.

Explanation of the incorrect option:

Option A:

1. Tissue is described as a structure of a collection of similar (simple tissue) or different cells to perform a certain function.
2. Tissue is a cellular (organizational) intermediary between cells and a whole organ.
3. Multiple tissues are then grouped together to form organs.

Option B:

Every organ is composed of two or more tissues, which are clusters of similar cells that collaborate to execute a certain activity.

Option C:

1. A plant cell has a big, solitary vacuole that is utilized for storage and to keep the cell's structure.
2. Animal cells, on the other hand, have numerous tiny vacuoles.

Final answer: The correct option is prokaryotes do not have a nucleus.
