b) Identify one similar and one different way each type of cell [prokaryote and eukaryote] uses flagella.
My answer:
In both prokaryotes and eukaryotes, flagella protrude from the cell's surface and enable movement. Prokaryotic flagella rotate, propelling the organism through its environment at speeds of up to 20 cell lengths per second, which is also done in the eukaryotic cells. There are, however, some differences in how each cell uses flagella. In a eukaryotic cell, flagella moves substances across the cell's surface, something not done in a prokaryotic cell.
Is this OK?
Thanks

it is ok
Your answer is partially correct. In both prokaryotes and eukaryotes, flagella are used for movement, but there are additional similarities and differences that can be mentioned.
Similarities:
1. Movement: Both prokaryotes and eukaryotes use flagella for locomotion. The flagella protrude from the cell surface and enable the cell to move through its environment.
Differences:
1. Structure: Prokaryotic flagella are typically simpler in structure, composed of a protein called flagellin, while eukaryotic flagella are generally more complex and consist of a microtubule-based structure called the axoneme.
2. Type of Movement: Prokaryotic flagella rotate like a propeller, generating a spinning motion that propels the organism through its environment. On the other hand, eukaryotic flagella undulate in a wave-like motion, allowing the cell to move using a whip-like motion.
3. Function: In prokaryotes, flagella primarily serve for locomotion, allowing the cell to swim towards nutrients or away from harmful substances. In eukaryotes, besides locomotion, flagella also have other functions. For example, in some eukaryotic cells, flagella are involved in moving substances across the cell's surface, creating fluid flow and aiding in processes such as circulation and the movement of mucus.
To enhance your answer, you can include these additional similarities and differences.
