What is the meaning of pseudopod?

What is the meaning of pseudopod?

Definition of pseudopodium 1 : a temporary protrusion or retractile process of the cytoplasm of a cell (such as an amoeba or a white blood cell) that functions especially as an organ of locomotion or in taking up food or other particulate matter — see amoeba illustration.

What are Axopods?

axopod (plural axopods) Any of a group of thin pseudopods containing complex arrays of microtubules and enveloped by cytoplasm.

Why is it called pseudopodium?

Pseudopod comes from the Greek words pseudes and podos, meaning “false” and “feet” respectively. They are projections of the cytoplasm of unicellular protists or eukaryotic cell membrane. The cytoplasm fills the lamellipodium to form the projections, or the pseudo.

What do you mean by Heterogametes?

Medical Definition of heterogamete : either of a pair of gametes that differ in form, size, or behavior and occur typically as large nonmotile female gametes and small motile sperms.

What are pseudopodia Class 7?

Pseudopodia are temporary projections of the cell membrane of eukaryotic cells. Amoeba eats food by spreading out their pseudopodia around their food particle and then engulfing it. Food gets locked inside the food vacuole, where digestive fluids are produced, converting it to simpler components.

What is sol gel theory?

Sol-Gel Theory or Change of Viscosity Theory: It is supposed to be the best to explain the locomotion in Amoeba. This theory is based on the reversible change of protoplasm from sol to gel state. This theory was proposed by Hyman (1917) and strongly supported by Pantin (1923-26), Mast (1925-31) and others.

What is the function of a pseudopodium?

pseudopodium, also called pseudopod, temporary or semipermanent extension of the cytoplasm, used in locomotion and feeding by all sarcodine protozoans (i.e., those with pseudopodia; see sarcodine) and some flagellate protozoans.

What is Isogamate?

Definition of isogamete : a gamete indistinguishable in form or size or behavior from another gamete with which it can unite to form a zygote.
