what are pseudopodia in amoeba what are the function of pseudopodia
Pseudopodia A pseudopod or pseudopodium (plural: pseudopods or pseudopodia) (from the Greek word ψευδοποδός, ψευδός "false" + ποδός "foot") is a temporary cytoplasm-filled projection of a eukaryotic cell membrane or a unicellular protist. Pseudopods may be used for motility, or for ingesting nutrients or other particulate matter. Cells that make pseudopods are generally referred to as amoeboids. Pseudopods extend and contract by the reversible assembly of actin subunits into many microfilaments. Filaments near the cell's end interact with myosin which causes contraction. The pseudopod extends itself until the actin reassembles itself into a network.
Cilium The functioning of motile cilia is strongly dependent on the maintenance of optimal levels of fluid bathing the cilia. Epithelial sodium channels ENaC that are specifically expressed along the entire length of cilia apparently serve as sensors that regulate fluid level surrounding the cilia.[12][14]
Egg Reproductive structures similar to the egg in other kingdoms are termed "spores," or in spermatophytes "seeds," or in gametophytes "egg cells".
Animal Animals are eukaryotic, multicellular organisms that form the biological kingdom Animalia. With few exceptions, animals are motile (able to move), heterotrophic (consume organic material), reproduce sexually, and their embryonic development includes a blastula stage. The body plan of the animal derives from this blastula, differentiating specialized tissues and organs as it develops; this plan eventually becomes fixed, although some undergo metamorphosis at some stage in their lives.
