The correct option is B False

Robert Hooke was mathematician and physicist. He discovered the cell. He took a piece of spanish oak and prepared thin slice by means of sharp pen knife. A deep planoconcave lens was used for throwing light on cork piece. The latter was observed under the microscope. The piece of cork was found to have a honey comb structure with a number of box like compartments, each having a pore and separated from others by diaphragms. Robert Hooke named the compartments as cellulae, now known as cells.
Nucleus was discovered by Robert Brown. He discovered the presence of nucleus in the cells of orchid root. Nucleus is a specialized double membrane bound protoplasmic body which contains all the genetic information for controlling cellular metabolism and transmission to the posterity.
