Cellulose microfibrils of a cell wall Featured 20 Mar 1985 Print

Cellulose microfibrils of a cell wall

Scanning electron micrograph of the surface of a protoplast (cell with wall removed) from a leaf of the tobacco plant Nicotiana tabacum. The micro- graph shows cellulose microfibrils regrowing over the plasma membrane after 14 hours in a chemical solution; the fibrils will eventually form a thick, smooth, durable outer coat. The ability to remove the cell wall makes possible experiments such as nuclear fusion and DNA microinjection, a method for transference of genetic information. The work is relevant to agriculture, biotechnology & medicine. Magnification: X 3430 at 35mm size. 8x10ins = X 24, 000
