Solution
Discovery of cell:
Cell was first discovered and named in 1665 by an English scientist Robert Hooke. He was examining a thin slice of cork and observed that the cork resembled the structure of honeycomb consisting of many little compartments. He called these compartments as cells (meaning 'little room' in Latin).
In 1838, Jakob Matthias Schleiden first proposed the idea that all plants consist of cells.
In 1839, Theodor Schwaan proposed that all animals and plants are made up of cells.
