Question

Amoebae move by crawling over a surface (cell crawling), which involves ________. amoebae move by crawling over a surface (cell crawling), which involves ________. assembly of microtubule extensions that vesicles can follow in the direction of movement reinforcement of the pseudopod with intermediate filaments growth of actin filaments to form bulges in the plasma membrane localized contractions driven by myosin and microtubules

Answer 1

Actin filaments are found in cells that form cytoskeletal structures. These are generally present below the plasma membrane. 

Amoebae move by crawling over a surface (cell crawling), which involves GROWTH OF ACTIN FILAMENTS TO FORM PSEUDOPODIA. Pseudopodium is a bulge in the plasma membrane towards the direction of movement.
