Most of the proteins comprise a family called major royal jelly proteins.
Cells were first discovered by Robert Hooke in 1663.
Robert Hooke was credited with discovering cells in 1663. Robert Hooke built his own compound microscope and used it to examine thin slices of cork. Cork is from the bark of the cork oak tree and is made up of cells that are dead. Hooke saw what appeared to be lots of little rectangular rooms. Hooke named them cells which means small rooms.
