Question

Which one of the following statements about animal cell centrosomes is correct?

1) They contain a 9-triplet arrangement of centrioles.
2) Animal cells have centrosomes, while plant cells do not have centrosomes.
3) They have exactly the same structure in plant and animal cells.
4) They include a pair of centrioles that are arranged perpendicular to one another.
5) None of the above are characteristics of animal cell centrosomes.

Answer 1

The correct statement about animal cell centrosomes is that they include a pair of centrioles arranged perpendicular to each other, which is important for cell division.

Step-by-step explanation:

The correct statement about animal cell centrosomes is that they include a pair of centrioles that are arranged perpendicular to one another. This arrangement is crucial for its role in microtubule organization, especially during cell division. Unlike plant cells, which generally lack centrioles, animal cells contain centrosomes with centrioles, aiding in the assembly of the mitotic spindle necessary for mitosis.
