Question

eukaryotic flagella differ from bacterial flagella because only eukaryotic flagella

multiple choice

contain microtubules

are long, whiplike structures

facilitate phototaxis

are used for cell motility

facilitate chemotaxis

Explanation:

Eukaryotic flagella are composed of microtubules arranged in a 9 + 2 pattern. Bacterial flagella are made of the protein flagellin and do not contain microtubules. Both types can be long, whip - like structures for cell motility, and can be involved in taxis (phototaxis and chemotaxis).

Answer:

A. contain microtubules
