Verified step by step guidance

Understand the role of mitotic spindles: Mitotic spindles are structures that separate chromosomes during cell division, specifically during mitosis.

Identify the cell structure responsible for forming mitotic spindles: Centrosomes are the organelles that organize microtubules and are crucial for the formation of mitotic spindles.

Differentiate between the given options: Ribosomes are involved in protein synthesis, the nucleolus is involved in ribosome production, and the Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids.

Recognize the function of centrosomes: Centrosomes serve as the main microtubule organizing centers in animal cells and play a key role in the formation of the mitotic spindle during cell division.

Conclude that centrosomes are the correct answer: Based on their function in organizing microtubules and forming the mitotic spindle, centrosomes are the cell structure from which mitotic spindles arise.
