Question

The correct sequence of plants which help in production of biofertilizers, medicines and protein food is:

• A. Belladona, Aloe, Withania
• B. Nostoc, Datura, Chlorella
• C. Chlorella, Datura, Nostoc
• D. Nostoc, Anabaena, Rhizobium

Hint:

To remember the plants in the sequence, associate them with their respective uses: biofertilizers, medicine, and protein food.

Answer 1

The Correct Option is B

The correct sequence is Nostoc, Datura, Chlorella.
Nostoc is a cyanobacterium that helps in nitrogen fixation and is used as a biofertilizer.
Datura is used in medicine for various treatments.
Chlorella is used for its high protein content, providing essential nutrients and is also used as a biofertilizer.

Answer 2

To solve the problem, we need to determine the correct sequence of plants that aid in the production of biofertilizers, medicines, and protein food.

1. Understanding the Role of Plants:
The plants mentioned, such as Belladonna, Aloe, Withania, Nostoc, Datura, and Chlorella, play significant roles in various industries, including medicine, biofertilizer production, and protein food manufacturing.

2. Analyzing the Options:
Let's examine the possible options based on their known uses:

• Belladonna, Aloe, Withania: Belladonna is known for its medicinal properties, Aloe is widely used in the production of skincare products, and Withania is used for medicinal purposes, but none of these plants are directly involved in biofertilizer production.
• Nostoc, Datura, Chlorella: Nostoc is a nitrogen-fixing cyanobacterium often used in biofertilizer production. Datura is not known for its role in biofertilizer but has medicinal uses. Chlorella is a type of algae used in protein food production and biofertilizers.
• Chlorella, Datura, Nostoc: This is a similar grouping but with Chlorella listed first, which is a protein-rich algae that contributes to both biofertilizer and food production.
• Nostoc, Anabaena, Rhizobium: All three of these organisms are nitrogen-fixing microbes, which are crucial for biofertilizer production. Anabaena and Rhizobium are also known for their symbiotic relationships with plants to enhance soil fertility.

3. Correct Answer:
The correct sequence, based on their roles in biofertilizers and food production, is Option (B): Nostoc, Datura, Chlorella.

Final Answer:
The correct sequence of plants is Nostoc, Datura, and Chlorella.
