Which of the following statements regarding cell organelles is incorrect?

Options

  1. AThe Golgi apparatus is an important site for the formation of glycoproteins and glycolipids.
  2. BIn animal cells, the smooth endoplasmic reticulum is a major site for the synthesis of lipid-like steroidal ho
  3. CThe nucleolus is a membrane-bound spherical structure which serves as a site for active ribosomal RNA synthesi
  4. DIn Amoeba , the contractile vacuole plays an important role in osmoregulation and excretion.

Correct answer

C. The nucleolus is a membrane-bound spherical structure which serves as a site for active ribosomal RNA synthesi

Step-by-step solution

The nucleolus is a non-membrane bound spherical structure present in the nucleoplasm. It is the site for active ribosomal RNA (rRNA) synthesis. Therefore, the statement that it is a membrane-bound structure is incorrect. The Golgi apparatus is indeed the important site for the formation of glycoproteins and glycolipids. The smooth endoplasmic reticulum is the major site for the synthesis of lipids, including lipid-like steroidal hormones in animal cells. In Amoeba , the contractile vacuole is important for osmoregu
