Question

An elaborate network of cytoplasmic filamentous proteinaceous structures which help in the maintenance of cell shape are

• A. Plasmalemma
• B. Cytoskeletones
• C. Endoplasmic reticulum
• D. Thylakoids

Answer 1

Answer: (B)

Cytoskeletones

An elaborate network of filamentous proteinaceous structures present in the cytoplasm is collectively referred to as the cytoskeleton. The cytoskeleton in a cell is involved in many functions such as mechanical support, motility, maintenance of the shape of the cell. The distribution and orientation of organelles are also regulated by them. Cytoskeletal structures are of three types-microfilaments, intermediate filaments and microtubules.

So, the correct answer is option B.
