Amoeboid Movement - Encyclopedia.com
2018年5月18日 · Amoeboid movement is brought about by reversible changes in the actin filaments of the cell's cytoskeleton. Cross-linking of these filaments by other proteins creates a three-dimensional network with gel-like properties in the plasmagel region.
Amoeba - Encyclopedia.com
2018年5月29日 · These are used for locomotion and feeding and result in a constantly changing body shape (see amoeboid movement). Most species are free-living in soil, mud, or water, where they feed on smaller protoctists and other single-celled organisms, but a few are parasitic. The best known species is the much studied A. proteus.
Physicists Explain Amoeboid Movement - Physics Forums
2010年7月6日 · Studying amoeboid movement can help us understand the mechanics of cell movement, which has implications in fields such as biomedicine and robotics. For example, researchers have used principles of amoeboid movement to develop soft robots that can move and adapt to their environment.
amoebocyte | Encyclopedia.com
Amoebocytes are named after their resemblance, especially in their movement, to Amoeba (see amoeboid movement) and they feed on foreign particles (including invading bacteria). They occur, for example, in sponges and mammalian blood (e.g. Source for information on amoebocyte: A Dictionary of Biology dictionary.

Pseudopodia - Encyclopedia.com
pseudopodium In amoeboid cells, a protrusion, usually temporary, of the cell body, which functions in locomotion and in the ingestion of food particles. In slime moulds, an arm-like projection from the body, by which the organism creeps over the surface.
Locomotion - Encyclopedia.com
2018年6月27日 · For a microscopic crustacean or an amoeba, however, movement through water is like crawling through molasses. There are three types of locomotion commonly employed by tiny aquatic organisms. One is amoeboid motion, which is used by its namesake Amoeba and some other protozoans, as well as by
Plasmodium - Encyclopedia.com
2018年6月11日 · The plasmodium is the vegetative phase of the slime mould, often seen as a slimy layer on decaying wood; it is capable of slow amoeboid movement and feeds by engulfing particles of decaying organic matter.
