Which statement is not true concerning the cytoskeleton of the cell? a) microtubules can be found in cilia and flagella b) microfilaments move the chromosomes during cell division c) microfilaments are the thinnest of the cytoskeletal fibers and aid in muscle contraction d) intermediate filaments are more permament fixtures of the cytoskeleton than are the other two classes & they reinforce cell shape.

The correct answer is option B.

Explanation:

A cytoskeleton is responsible for aligning structure to the cell and associates it with the components of the cell membrane and the organelles. The key components of the cytoskeleton in eukaryotes are the microfilaments and microtubules. Both in combination permit the cell to maintain its configuration and helps in the process of movement.  

Of the mentioned statements, the incorrect one is statement B, as it is the microtubule, not microfilament, which helps in the movement of the chromosome at the time of cell division. At the time of cell division, the microtubules align themselves into a composition known as the spindle that pulls the chromosomes away from each other.  

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
