Question
Q. Consider the following statements, with reference to Algae:
Which of the above given statements is correct?
- Algae generally thrive in nutrients rich water.
- Algae can be used to produce Bioplastics.
- Proteins are found in microalgae.
- Algae are found in all environments except snowy regions.
Which of the above given statements is correct?
Answer: Option D
:
D
Explanation:
Alga is a term that describes a large and incredibly diverse group of eukaryotic, photosynthetic life forms. It can be unicellular or multicellular.
Statement 1 is correct: Algae flourish in nutrient-rich waters such as urban wastewater (sewage), animal waste and some industrial effluents, while at the same time purifying such waste and creating a biomass suitable for biofuels.
Statement 2 is correct: Algae produce a variety of base materials that can be used for bioplastics production. Most important are carbohydrates and hydrocarbons
Statement 3 is correct: Microalgae contain similar raw materials as traditional crops: high-quality oils, proteins, pigments as well as hydrocarbons and sugars.
Statement 4 is incorrect: Algae can survive in snowy regions too. They live in ocean to pond environments. It is commonly green, but can be found in a number of colours. In addition to chlorophyll, for example, algae living in snow produce carotenoid pigments, thus giving the surrounding snow a distinctive red colour.
