What is the distal tip in a lobopodium?
Answers
Lobopodia may be flattened or cylindrical (tubular). Amoeba proteus is probably the best-known protist possessing lobopodia. Although the precise mechanisms of amoeboid movement are unresolved, there is general agreement that contraction of the outer, nongranular layer of cytoplasm (the ectoplasm) causes the forward flow of…

Actin and myosin microfilaments, adenosine triphosphate (ATP), calcium ions, and other factors are involved in various stages of this complex process.
