What did Robert hooke cal the structures in cork that no one had seen before?

Answer 1

Because the boxlike cells of cork reminded him of the cells in which live at a monastery.

From my biology book-chapter7 section 1.

Answer 2

Robert Hooke called the structures he observed in cork "cells." He described them as small, box-like compartments that he compared to the cells in a monastery, leading to the use of the term "cell" in Biology.

Answer 3

They resembled small rooms. He then decided upon calling them cells because they resembled cells more so than small rooms. That is how the name for cells originated.
