Bacterial flagella have a biological motor that spins within the cell wall and is powered by ATP. This allows the flagella to spin in a whiplike motion to propel the bacterium. Is this statement True or False?

False

Explanation:

Bacterial flagella have a biological motor that spins within the cell wall and is NOT powered by ATP.

Instead the Bacterial flagella is known as the biological motor that spins the flagella for the motion of the bacteria and is as a result of the electron imbalance in the membranes which helps in the generation of a gradient. The cells makes use of the energy present in the gradient through the help of proton motive force which helps to propel it.

for the points

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
