An elaborate network of filamentous proteinaceous structures present in the cytoplasm which helps in the maintenance of cell shape is called?
An elaborate network of filamentous proteinaceous structures present in the cytoplasm which helps in the maintenance of cell shape is called?
The correct option is D cytoskeleton
The correct option is D.
Explanation of correct option:
- The cytoskeleton is a dynamic and complex network of protein filaments. It gives the cells mechanical support thereby maintaining their shape and organization internally.
- The cytoskeleton is made of microfilaments, intermediate filaments, and microtubules.
Explanation of incorrect option:
Option A:
The endoplasmic reticulum is an interconnected network of a sac-like structure primarily involved in the synthesis of proteins and lipids.
Option B:
The plasmalemma refers to the cell membrane. It is primarily made of lipids that form a bilayer around various cellular components.
Option C:
The thylakoids are disc-like membranous sacs present within the chloroplasts responsible for carrying out photosynthesis.
Final answer: An elaborate network of filamentous proteinaceous structures present in the cytoplasm which helps in the maintenance of cell shape is called the cytoskeleton.
