motility
Sperm.
No. The hormone RELAXIN combines with the enzymes in semen to enhance sperm motility.
True
Pseudomonas aeruginosa displays true motility. It is able to actively move or swim through liquid environments by using its flagella. Brownian motion, on the other hand, is the random movement of particles due to collision with surrounding molecules and does not involve active motility.
Cells will exhibit independent movement over greater distance.
P. aeruginosa and S. volutans exhibit true motility on slides. B. cereus is not typically motile.
Staphylococcus epidermidis does not have true motility like flagella-driven movement, but it can exhibit Brownian motion due to random thermal energy causing cells to move passively. This movement is not directional or controlled by the bacteria, unlike true motility.
