Question

Mechanical support to the cell is provided by

• A. Golgi bodies
• B. Microfibrils
• C. Endoplasmic reticulum
• D. Chromatids

Answer 1

The correct option is B Microfibrils

Golgi body has main function of modifying, sorting and packaging the proteins, which are synthesized by cells. Golgi bodies are also involved in transport of lipid molecules across the cell. Golgi bodies also create lysosomes. But golgi bodies are not involved in providing mechanical support to the cell. Therefore, option A is incorrect.
Endoplasmic reticulum is involved in correct and functional folding of newly formed protein molecules and their transport to vesicles of Golgi apparatus or Golgi body. Therefore, option C is incorrect.
Chromatid is one copy of duplicated chromosome. It is not involved in providing mechanical support to the cell. Therefore, option D is incorrect.
Microfibrils are part of cytoskeleton, which provides mechanical support to the cell. They are fine fibril; consisting of glycoproteins and cellulose. They are observed in 9 + 2 pattern, in which two central fibrils are surrounded by other pairs. Therefore, option B is correct.
