Impossible*
Hooke's discovery dealt with cells, which are extremely tiny that it is impossible to be seen with the naked eye. So, without the microscope, he would not have been able to see it.
He first discovered the cell with his simple microscope.
You cant see a cell without just looking at it
Because it was the first microscope ever made with to lenses :)
in.............. 1665 - 1683
it was better because he added new stuff to his microscope and made it interesting
Micrographia, reporting things that he had seen through his microscope.
His microscope was different because it used an oil lamp to produce a flame which gave off light.
Robert Hookes microscope had either two or more lenses. a simple microscope has one lens in it.
Because cells are the building blocks of every living thing.
Robert was famous for discovering cells and springs and elasticity. He first discovered cells in cork samplings and then in plant tissue. For this, Robert used a microscope said to have been "an early microscope."
