Dmitriy789 [7]

Answer:

Option-B

Explanation:

Schleiden was a German botanist and Schwann was a German zoologist who independently observed that plants and animals are made of cells.

In the given question, since Schwann was a zoologist, therefore, he concluded that the cell in an organism must function properly whereas Schleiden was a botanist and concluded that the different structures of a plant are composed of cells.
