Solution
The correct option is B Diatoms
- They are found in freshwater as well as in marine environments. They are microscopic and float passively in water currents (plankton).
- Most of them are photosynthetic. In diatoms, the cell walls form two thin overlapping shells, which fit together as in a soapbox. The walls are embedded with silica and thus the walls are indestructible.
- So, the correct answer is "Diatoms'.
