NEET BIOLOGY

Detailed explanation-1: -Pseudopodia are responsible for cell movement and help in capturing food. In feeding, pseudopodia flow around the particle and engulf it, forming a food vacuole.

Detailed explanation-2: -Flagella are long projections that move in a whip-like motion. Flagella and cilia are the major means of locomotion in unicellular organisms. 1.

Detailed explanation-3: -Cilia and flagella are microtubule-based projections of the plasma membrane that are responsible for movement of a variety of eukaryotic cells. Many bacteria also have flagella, but these prokaryotic flagella are quite different from those of eukaryotes.

Detailed explanation-4: -The cytoskeleton provides a structural framework for the cell, serving as a scaffold that determines cell shape and the general organization of the cytoplasm. In addition to playing this structural role, the cytoskeleton is responsible for cell movements.

Detailed explanation-5: -The dynein motor proteins generate the motive force to bend the flagellum and cause it to move with a whip‐like motion through the surrounding fluid. This motion is referred to as the flagellar or ciliary beat.
