Question

What do amoeba use for movement?

Answer 1

Hint: A single-celled organism known as an amoeba catches food and moves about by spreading fingerlike protoplasm projections. Amoebas may be free-living or parasitic in damp conditions.

Complete answer:
A pseudopod, also known as a pseudopodium, is a temporary arm-like projection of a eukaryotic cell membrane that grows in the direction of movement. Pseudopodia are cytoplasm-filled structures that mainly contain actin filaments, but may also contain microtubules and intermediate filaments. Pseudopods are used for ingestion and motility. Pseudopodia is mostly found in amoeba. Amoebae do not have cell walls, allowing them to move freely. Pseudopods, which are bulges of cytoplasm created by the coordinated action of actin microfilaments pushing out the plasma membrane that surrounds the cell, are used by amoebae to travel and feed. Pseudopods are used to classify amoebae groups based on their appearance and internal structure. Bulbous (lobose) pseudopods, rounded at the ends and roughly tubular in cross-section, are common in amoebozoa species, such as those in the genus Amoeba. Euglypha and Gromia are Cercozoa amoeboids with slender, thread-like (filose) pseudopods. Foraminifera produce fine, branching pseudopods that combine to form reticulose (net-like) structures. Radiolaria and Heliozoa, for example, have rigid, needle-like radiating axopodia (actinopoda) that are supported from within by bundles of microtubules.

Note:
Amoebae eat a variety of items. Some amoebae are predatory, eating bacteria and other protists to survive. Some species are detritivores, meaning they consume dead organic matter. Amoebae consume their food via phagocytosis, which involves extending pseudopods to encircle and engulf live prey or scavenged material.
