The solid linear cytoskeletal elements having a diameter of 6 nm and made up of a single type of monomer are known as:Microfilaments are solid, rod-like cytoskeletal elements about 6 nm in diameter made of a single protein, actin.
Microtubules are hollow (about 25 nm) and made of tubulin; intermediate filaments are about 10 nm.

An elaborate network of filamentous proteinaceous structures present in the cytoplasm which helps in the maintenance of cell shape is calledNCERT: 'An elaborate network of filamentous proteinaceous structures present in the cytoplasm is collectively referred to as the cytoskeleton.'
It consists of microtubules, microfilaments and intermediate filaments.
The cytoskeleton is involved in many functions such as mechanical support, motility and maintenance of the shape of the cell.
Thylakoids are the membranous sacs of chloroplasts, the endoplasmic reticulum is a network of membranous tubules, and the plasmalemma is the cell membrane.
Hence the structure is the cytoskeleton.
