Cell Theory Quiz

Cell Theory and Discovery

• The discovery of cells is largely attributed to Robert Hooke.
• The cell theory proposes that cells arise from pre-existing cells, contradicting the idea of spontaneous generation.
• According to the cell theory, cells are considered the basic unit of structure in all organisms.

Early Observations of Cells

• Robert Hooke's observation of cork under the microscope was shocking because it revealed that cork tissue was composed of small, empty chambers, resembling tiny rooms, which he called "cells".
• Matthias Jakob Schleiden and Theodor Schwann also studied cells of both animal and plant tissues, and discovered significant differences between the two types of cells.
