Question

5. The nucleus controls all the activities of the cell and acts as a site of DNA material
and protein synthesis. It is composed of some components which all together give
the nucleus its functionality. Here is shown a figure of nucleus with some of its
components labeled as A, B, C and D. can you name these components correctly?
(a) A – Nucleons; B – Chromatin; C – Nuclear membrane; D – Nucleoplasm
(b) A – Nucleus; B – Chromatin; C – Nuclear membrane; D – Nucleoplasm
(c) A – Nucleolus; B – Chromatin; C – Nuclear membrane; D – Nucleoplasm
(d) A – Nucleolus; B – Chromatin; C – Nuclear membrane; D – Nuclear wall

Answer 2

Answer:

(c) A – Nucleolus; B – Chromatin; C – Nuclear membrane; D – Nucleoplasm is the correct option.

Explanation:

The real nucleus is an organelle found mostly in eukaryotic cells that contains the genetic information of the organism.

• The cell nucleus mainly consists of the nuclear envelope, nucleoplasm, nucleolus, and chromosomes.
• Nucleoplasm is the name given to the matrix found within the nucleus, also known as karyoplasm.
• The two-layered structure that surrounds the nucleus components is known as the nuclear membrane.
• Chromatin, which is made up of DNA and protein components, contains genetic information.
• Chromatin is further classified into heterochromatin and euchromatin based on its roles.
• The nucleolus is a sturdy spherical structure located within the nucleus. The nucleolus indirectly contributes to protein synthesis by producing ribosomes.
