(A) Bacteria (6) fungi (C) Algae (D) All of these​

Answer 1

Answer:

(D) All of these

Explanation:

Animalcule is an old term for microorganisms that included bacteria, protozoans, and very small animals.

Microorganisms had first been seen by Anton Van Leeuwenhoek (1676) in pepper-water which had been allowed to stand exposed to air. There was no particular classification for the organisms at the time. Hence he observed all kinds of microorganisms and named all of them as animalcules. So, Animalcules include Bacteria, protozoans, fungi, algae etc.
