Solution

The correct option is B

cytoskeleton


The correct option is B.

Explanation of correct option:

  1. The cytoskeleton is a dynamic and complex network of filaments made of proteins. It helps in maintaining the cell organization and shape by providing mechanical support.
  2. They are made of microfilaments, intermediate filaments, and microtubules.

Explanation of incorrect option:

Option A:

The cytoplasm is the solution comprising various proteins and ions in water. It is enclosed by the cell membrane. All the cell organelles are present in the cytoplasm.

Option C:

The endoplasmic reticulum forms a series of interconnected sac-like structures primarily involved in protein and lipid synthesis.

Option D:

The Golgi complex helps in the packing and transportation of proteins via membrane-bound vesicles.

Final answer: An elaborate network of filamentous proteinaceous structures which help in the maintenance of the cell shape is called the cytoskeleton.
