1. Microalgae are renewable economical sources of biofuels, bioactive medicinal products, and food ingredients.
2. Microalgae grow in water and absorb nutrients directly instead of roots.
3. Microalgae require high fertile lands to grow and they are extremely dependent on local weather patterns..
Which of the statements given above are correct?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

Answer: A
Notes:

Statement 1: Microalgae are renewable, sustainable, and economical sources of biofuels, bioactive medicinal products, and food ingredients.

Statement 2: Microalgae are a diverse group of microscopic aquatic organisms. Like plants, they generate energy from sunlight through photosynthesis. But they differ from plants in basic ways as they grow in water instead of on land and absorb nutrients directly instead of via roots.

Statement 3: The statement is incorrect. Microalgae don’t require fertile land. It is largely independent of local weather patterns and could potentially recycle water. It has elevated productivity and scope for continuous harvests.
