Question

(3.2) Which of the following is FALSE regarding the nucleolus?

A. It picks up stain heavily therefore appears dark under the microscope
B. It makes ribosomal RNA, which helps with creating of ribosomes
C. It is surrounded by a thick gel-like fluid called the nucleoplasm
D. It is an organelle in the cytoplasm

Answer 1

The false statement about the nucleolus is that it is an organelle in the cytoplasm. In truth, the nucleolus is a dense area within the nucleus responsible for the manufacturing of ribosomal RNA and assembly of ribosome subunits. Therefore, the correct option is D

Step-by-step explanation:

The statement that is FALSE regarding the nucleolus is: D. It is an organelle in the cytoplasm. The nucleolus is not an organelle in the cytoplasm but a region within the nucleus. The nucleolus appears dark under a microscope because it picks up stain heavily (A). It is involved in making ribosomal RNA (rRNA), which is crucial for the creation of ribosomes (B). The nucleolus is surrounded by a semi-solid fluid known as the nucleoplasm (C). The nucleoplasm contains the chromatin and nucleolus and provides a medium for the transportation and exchange of materials necessary for ribosome synthesis and other nuclear functions.
