Question
Some bacteria have one or more flagella. What is true about these structures?
1. Bacteria use flagella to move around in their environment
2. Bacteria use flagella to attach themselves to another bacterial cell
3. Bacterial flagella are molecularly similar to those found in eukaryotes and archaea
4. Flagella have convergently evolved in bacteria, archaea, and eukaryotes
5. Flagella are always found concentrated on one part of the cell
a) Only 1 b)Only 2 O d Only 1 and 3 O d) Only 1 and 4 ( e) All statements are trueExplanation / Answer
Option 1 is the correct answer
In bacteria, flagella is used for locomotion, i.e to move around in their environment. Bacterial flagella differ in structure from eukaryotic flagella in that they are made up of protein flagellin as compared to eukaryotic flagellum which is made up of microtubules. Attachement to other bacterial cells is done through pili and fimbriae. Flagella can be found on all parts of bacterial cell.
