False-colour scanning electron micrograph (SEM) of Cyclotella meneghiniana,a diatom found in the brackish water of saline or polluted streams & lakes. Diatoms are a type of alga. They consist of two valves,made of silica,which fit together like the top & bottom of a box. The valves are often decorated with tiny pores,ridges,spikes or other projections. This SEM shows clearly the surface of one valve & the broad "girdle" connecting it to the other valve. Magnification: x1785 at 6x6cm size. JBU colouring: green & yellow. BW original is B305/17M | |
