Question

In Amoeba, pseudopodia are formed due to

• A. Contact with food
• B. Sol $\rightleftharpoons$ gel change
• C. Movement towards area of higher temperature
• D. All the above

Answer 1

Answer: (B)

Sol $\rightleftharpoons$ gel change

A pseudopodium is a temporary cytoplasm-filled projection of unicellular eukaryotic cell (Amoeba). Movement of pseudopodia of Amoeba are due to change in viscosity and it is explained by Sol-Gel theory. This theory is based on the reversible change of protoplasm from sol state(less viscous) to gel state(more viscous).

So, the correct answer is 'Sol ⇌⇌ gel change'
