Question

PLEASE HEP A student claims that a cytoskeleton is a structure unique to animal cells whose sole

Answer 1

Answer:

Explanation:

This statement is incorrect because the Cytoskeleton is not unique to animal cells. Vegetal cells also have a cytoskeleton.

Answer 2

Answer:

The cytoskeleton is a unique structure of all eukaryotic cells, which are all cells that have true nucleus. Thus we can say that the cytoskeleton is present in cells animal, plant cells and any other eukaryotic cell.

Explanation:

The cytoskeleton is a complex network of fibers found in eukaryotic cells that allows them to adopt various shapes and perform the most varied movements. It is composed of three types of molecular structures: the microtubules, the actin microfilaments or filaments and the intermediate filaments.

The cytoskeleton therefore has several functions, which can be summarized as follows:

• Ensures shape and mechanical support of the cell;
• Promotes movement of cytoplasmic organelles and vesicles;
• Important in cellular contraction;
• Enables amoeboid movements.

Importantly, the cytoskeleton, because it ensures the movement of vesicles and can manipulate the plasma membrane, enables processes such as endocytosis and exocytosis to occur.
