Question

What is the function of Diatoms?

Answer 1

Diatoms:

1. The diatoms are characterized by being unicellular with a silica-based cell wall.
2. Diatoms have glass-like walls (frustule) with silica (SiO₂)
3. Diatoms have oil drops made of sugar and starch and volutin inside their cells.
4. They have pores with patterns on their frustules.
5. Diatoms have different sizes and shapes.
6. Their body is completely covered by a parent siliceous shell (silica deposited in the cell wall).
7. These two valves fix like a soap box.
8. They have flagella only in the reproductive stage.
9. They are unicellular photosynthetic organisms.
10. They contain chlorophyll a and c.
11. They contain chlorophyll and carotenoids (a pigment) for golden color.

Functions of the Diatoms are:

1. Diatoms are able to photosynthesize.
2. They convert dissolved carbon dioxide in the water into oxygen.
3. They are a primary food source for higher organisms in the food chain, such as invertebrates and small fish.
4. Diatoms can also play important roles in the energy and nutrient cycles of water resources.
5. Diatoms are used as an insecticide, as they dry them by absorbing oil.
6. Some diatoms are used in making skin medicines.
7. Diatoms are used as toothpaste.
