Robert Hooke
Hooke coined the term cell for describing biological organisms, the term being suggested by the resemblance of plant cells to cells of a honeycomb.
James Till
Till started a series of experiments that involved injecting bone marrow cells into irradiated mice. They observed that small raised lumps grew on the spleens of the mice, in proportion to the number of bone marrow cells injected. Till and McCulloch dubbed the lumps 'spleen colonies', and speculated that each lump arose from a single marrow cell: perhaps a stem cell.
Earnest Mccullock.
Best known for demonstrating – with James Till – the existence of stem cells.
Robert Brown
In 1827, while examining grains of pollen of the plant suspended in water under a microscope, Brown observed minute particles, now known to be amyloplasts (starch organelles) and spherosomes (lipid organelles), ejected from the pollen grains, executing a continuous jittery motion.
Felice Fontana
Lynn Margulis
She was an American evolutionary theorist, science author, educator, and popularizer, and was the primary modern proponent for the significance of symbiosis in biological evolution.
Van Leewonhoek
He is commonly known as "the Father of Microbiology", and considered to be the first microbiologist. He is best known for his work on the improvement of the microscope and for his contributions towards the establishment of microbiology.
