Question

what would you hypothsis about observation of robert hooke discovery of cell

Answer 1

i. Robert Hooke (1665), an English scientist, discovered and coined the term cell which he mentioned in his book “Micrographic” in the chapter “observe-XVIII”.

While examining a thin slice of bottle cork under a self-designed compound microscope he noticed honey­comb like compartments or units (Fig. 1.1) which he called cells.

The term cell was derived from a Latin word cellular (meaning little room or chamber). The cork cells that Hooke observed were actually the cell wails surrounding the empty lumens of dead cells.

ii. Anton von Leeuwenhoek (1674), a Dutch microscopist, first observed living cells like bacteria from tartar of teeth, protozoans, erythrocytes, sperm cells etc.

ii. Robert Brown (1831), a Scottish botanist, discovered the presence of nucleus in the root cells of orchids.

iv. J.E. Purkinjee (1839), coined the term ‘protoplasm’ for the living substance present inside the cell. Huxley (1868) called it the “Physical oasis of life".
