Webb15 maj 2000 · The veins are channels for the protoplasmic flow, and the vein-arrangement index (VAI) indicates the direction of the flow itself. A plasmodium changes its vein organization, so the orientation of the veins is a quantitative function of time. VAI was determined as shown in Fig. 2. WebbIt is a type of movement that creeps through the protrusion of the cell’s cytoplasm, which involves the formation of pseudopods (“false feet”) and posterior uropods. One or more pseudopods can be produced simultaneously, depending on the organism.
