A pseudopod is a(n) ____
A
extra nucleus for reproduction
B
false foot for locomotion
C
whip-like extension for locomotion
D
second stage of protozoan life cycle
Explanation: 

Detailed explanation-1: -Amoeboid movement occurs as an extension of the cytoplasm, called a pseudopod (“false foot”), flows outward, deforms the cell boundary, and is followed by the rest of the cell. Many pseudopodia may be formed at the same time, and their actions do not seem to be…

Detailed explanation-2: -The term pseudopod is Greek in origin and translates to “false feet.” Pseudopodia are projections of the cytoplasm in organisms like the amoeba, other unicellular organisms, as well as some animal and human cells.

Detailed explanation-3: -Pseudopodia gives amoeboid movement to the cells which is a sliding or crawling-like form of locomotion. During feeding, the extensions either surround the prey and engulf it or trap it on a sticky mesh like structure.

Detailed explanation-4: -Amoeba can move in all directions using false feet called pseudopodia. It can change its shape with the help of these pseudopodia to exhibit locomotion. Hence, pseudopodia are known as a false foot in Amoeba, Food vacuole and water vacuole are used for the storage of food and water respectively.

Detailed explanation-5: -Amoeba is a unicellular organism and can exist independently. It uses pseudopodia for locomotion and engulfing food.
