WebA flagellum (/ f l ə ˈ dʒ ɛ l əm /; PL flagella) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates.. A microorganism may have from one to many flagella. A gram-negative bacterium Helicobacter pylori for example … WebThe sex cells are called gametes, and the product of their union is a zygote. All gametes are normally haploid (having a single set of chromosomes) and all zygotes, diploid (having a double set of chromosomes, one set from each parent). Gametes may be motile, by means of whiplike hairs (flagella) or of flowing cytoplasm (amoeboid motion).

WebMotile sperm cells typically move via flagella and require a water medium in order to swim toward the egg for fertilization. The sperm cells are the only flagellated cells in the life … WebMammalian sperm flagella also possess a mitochondrial and a fibrous sheath that encircle most of the axoneme. These sheaths and the ODFs add mechanical rigidity to the flagellum creating the functional effect of increasing bend wavelength, which requires the entrainment of more dynein motors in the production of a single wave. ...
