Which of the following statements describes a correct fact about cytoskeletal filaments?

a. each of the building blocks of the three major cytoskeletal filaments can bind to and hydrolyze nucleotides.
b. intermediate filaments are typically thinner than actin filaments but thicker than microtubules.
c. all three cytoskeletal filaments are polar structures all three cytoskeletal filaments provide support for the nucleus
d. the building blocks of f-actin and microtubules are globular proteins, whereas those of intermediate filaments are filamentous proteins themselves.

The correct statements that describes cytoskeletal filaments are :

i) Each of the building blocks of the three major cytoskeletal filaments can bind to and hydrolyze nucleotides ( A )

ii) The building blocks of F-actin and microtubules are globular proteins, whereas those of intermediate filaments are filamentous proteins themselves. ( D )

Cytoskeleton is the structure present in cells that helps the cells maintain its structure and organization. some of the functions of the cytoskeleton includes

Cytoskeleton is made up of cytoskeletal filaments which are essentially protein filaments present in the cytoplasm of cells. The intermediate filaments are filamentous proteins.

Hence we can conclude that  Each of the building blocks of the three major cytoskeletal filaments can bind to and hydrolyze nucleotides  and  The building blocks of F-actin and microtubules are globular proteins, whereas those of intermediate filaments are filamentous proteins themselves.

Following are the correct statements about cytoskeleton proteins

Explanation:

A complicated system contained in the cytoplasm that holds a network of protein filaments or fibres is called the proteins of same types of the different organisms. These cytoskeleton aids in the transport of materials from inside and outside of the cells, this happens through a number of inter cellular proteins.The cytoskeleton gives structure and  shape to the cell. Also provides support and helps in movement of intermediate filaments, micro filament and microtubules.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
