Answer:

Correct answer: (c) Cellulose and Silica

Explanation:

• Diatoms are photosynthesizing algae, they are also known as phytoplanktons.
• They are unicellular organisms, they are immotile and they exist either in solidarity or in groups called colonies.
• Diatoms are the major producers of the ocean.
• The cell wall of diatoms is composed of glass-like silica impregnated in cellulose. The cell wall is termed as frustules or shells.
• Diatoms are therefore known as the "jewels of the sea" or " opal algals" due to their glass-like appearance.
