COLUMN 1 COLUMN 2
A. Ganga action plan ii. Ministry of Environment and Forests
B. Bt cotton iii. Insect-resistant plant
C. Rhizobium iv. N2 fixing bacterium
D. Nostoc i. N2 fixing cyanobacterium

The Ministry of Environment and Forests has initiated Ganga Action Plan and Yamuna Action Plan to save these major rivers of our country from pollution. Under these plans, it is proposed to build a large number of sewage treatment plants so that only treated sewage may be discharged in the rivers.

Bt Cotton – Insect-resistant plant:
Bt cotton is a genetically modified crop that produces an insecticidal protein from the bacterium Bacillus thuringiensis (Bt). It provides resistance to pests like bollworms, reducing the need for chemical insecticides.

Rhizobium – N2 fixing bacterium:
Rhizobium is a genus of nitrogen-fixing bacteria that forms symbiotic relationships with legumes. It lives in root nodules of these plants, converting atmospheric nitrogen (N2) into a usable form for plant growth.

Nostoc – N2 fixing cyanobacterium:
Nostoc is a genus of nitrogen-fixing cyanobacteria (blue-green algae) that can convert atmospheric nitrogen into a form usable by plants. It is commonly found in soil and water and plays a role in the nitrogen cycle.
