Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The cytoplasmic extensions used by some protists to move are called ____
A
cilia
B
flagellum
C
spores
D
pseudopodia
Explanation: 

Detailed explanation-1: -protists. …cilia, pseudopodia are responsible for amoeboid movement, a sliding or crawlinglike form of locomotion. The formation of cytoplasmic projections, or pseudopodia, on the forward edge of the cell, pulling the cell along, is characteristic of the microscopic unicellular protozoans known as amoebas.

Detailed explanation-2: -Amoebozoa are a type of protist that is characterized by the presence of pseudopodia which they use for locomotion and feeding.

Detailed explanation-3: -Pseudopodia. Some small single-celled organisms such as amoeba use cytoplasmic extensions to crawl around to scavenge for food. These extensions are sometimes referred to as false feet; the more technical term for these false feet is pseudopodia.

Detailed explanation-4: -Amoebas are identified by their ability to form temporary cytoplasmic extensions called pseudopodia, or false feet, by means of which they move about. This type of movement, called amoeboid movement, is considered to be the most primitive form of animal locomotion.

Detailed explanation-5: -Locomotion. Protozoa move in the environment in three different ways: ameboid movement, flagella, and cilia. The ameboid movement is typical of ameboid protozoa (see below) and some other forms. Movement is achieved by cytoplasmic protrusions known as pseudopodia.
