Question

complete the following paragraph by matching the term to each statement about the cytoskeleton. the cytoskeleton is made of many types of filamentous ____ structures. these structures help maintain the cell’s __ as well as anchoring cellular organelles the hollow cylinders made up of 13 longitudinal rows of tubulin are called the __. the microtubules act as tracts for organelles to move and during cell division they form __ to assist with the movement of the chromosomes. the filaments which resist stress and form cell to cell junctions are called ____. terms (right side): shape, genetic material, carbohydrate, spindle fibers, microvilli, microtubules, microfilaments, protein

Explanation:

To solve this, we analyze each statement about the cytoskeleton:

1. First blank: The cytoskeleton’s filamentous structures are made of protein (cytoskeletal components like microtubules, microfilaments are protein - based).
2. Second blank: The cytoskeleton maintains the cell’s shape (a key function of the cytoskeleton is structural support for cell shape).
3. Third blank: Hollow cylinders of tubulin are microtubules (microtubules are composed of tubulin and have a hollow, cylindrical structure with 13 protofilaments).
4. Fourth blank: During cell division, microtubules form spindle fibers (spindle fibers are microtubule - based structures that move chromosomes).
5. Fifth blank: Filaments resisting stress and forming cell - cell junctions are microfilaments (microfilaments (actin filaments) have roles in cell integrity and junctions).

Filled Paragraph:

• The cytoskeleton is made of many types of filamentous \(\boldsymbol{\text{protein}}\) structures.
• These structures help maintain the cell’s \(\boldsymbol{\text{shape}}\) as well as anchoring cellular organelles.
• The hollow cylinders made up of 13 longitudinal rows of tubulin are called the \(\boldsymbol{\text{microtubules}}\).
• The microtubules act as tracts for organelles to move and during cell division they form \(\boldsymbol{\text{spindle fibers}}\) to assist with the movement of the chromosomes.
• The filaments which resist stress and form cell to cell junctions are called \(\boldsymbol{\text{microfilaments}}\).
