Which protist group typically consists of amoeboid cells surrounded by a hard outer shell through which cytoplasmic projections extend?
A) Rhizarians
B) Unikonts
C) Euglenoids
D) Archaeplastids
E) Opisthokonts
Hard Outer Shell
A protective external layer found in some animals, including crustaceans and certain insects, which offers defense against predators and environmental conditions.
Amoeboid Cells
Cells that move or feed by forming extensions of their cytoplasm, known as pseudopodia.
Rhizarians
A diverse supergroup of amoeboid cells that often have hard outer shells, called tests, through which cytoplasmic projections extend; include forams, actinopods, and certain shell-less amoebas.

Final Answer :
A
Explanation :
Rhizarians are a group of protists characterized by their amoeboid morphology, often with hard outer shells (tests) made of various materials, through which they extend cytoplasmic projections called pseudopodia for movement and feeding.
