There are 2 bacterial cell. Cell A can move in water while cell B cannot move in water. What do you conclude from it?
Cell A have flagella but no centriole.
Cell B lacks flagella and centriole as well.
Cell B have centriole as well as flagella.
Cell A have centriole but no flagella.
The filamentous organelles known as bacterial flagella propel the movement of the cell. When animal cells divide, the centrioles create the spindle fibers that become the spindle apparatus as well as the basal body of cilia or flagella. Hence option 2 is the correct answer.
Explanation for the incorrect options :
Option 1 is incorrect because cell A is having flagella hence it is moving. Flagella have formed from Centriole. Hence, cell A has both flagella as well centriole.
Option 3 is incorrect because cell B is not moving which means they are not having flagella. Flagella is form from centrioles. Hence, cell B lacks both centriole and flagella
Option 4 is incorrect because cell A is having flagella hence it is moving. Flagella form from centriole. Hence, cell A has both flagella as well centriole.
