“Let’s call these things cells!”
Robert Hooke (1665)
(1665; “Small Drawings”) he included his studies and illustrations of the crystal structure of snowflakes, discussed the possibility of manufacturing artificial fibres by a process similar to the spinning of the silkworm, and first used the word cell to name the microscopic honeycomb cavities in cork, ..
Micrographia (Robert Hooke)
He referred to such structure at the NUCLEUS
Robert Brown (1830)
A scottish Botanist who was responsible for discovery of the nucleus of the cell
Robert Hooke (1830)
identified a darkly stained structure at the centre of every cell he observed
Robert Hooke (1830)
Year of discovering of nucleus Robert Hooke
Year 1830
Proposed as a result of his experiments that all plants are made up of cells
Matthias Schleiden (1838)
First proposed by German scientists Theodor Schwann and Matthias Jakob Schleiden in 1838, the theory that all plants and animals are made up of cells
Matthias Schleiden (1838)
Who is the German Botanist
Matthias Schleiden: He is a German botanist who in 1838, examined a large number of plants, and concluded that all plant tissues are made up of cells and that an embryonic plant arises from a single cell.
Year of discovering that all plants are made of cell
Year 1838
Observe and proposed that all animals, are likewise made up of cells
Theodor Schwann (1839)
all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
Theodor Schwann (1839)
Who created the cell theory
Matthias Schleiden and Theodor Schwann gave the Cell theory. Matthias Schleiden, a German Botanist, discovered that all plants were made of cells in 1838.
Theodor Schwann year
Year 1839
Concluded that cells reproduce by forming new cells
Rudolf Virchow (1958)
