Question

Why is the presence of nitrogen important for plants?

Answer 1

Importance of nitrogen for plants:

• Nitrogen is the most abundant gas in the atmosphere.
• It is about 78% in our atmosphere.
• Nitrogen is very important for the growth and development of plants.
• Atmospheric nitrogen is converted into nitrites and nitrates ions by lightning and by some nitrogen-fixing bacteria.
• Plants then absorb these ions through their roots along with water.
• In this way plants use nitrogen for their growth and development.
• Fertilisers are also used to provide nitrogen to plants.
• Therefore, for the proper growth and development of plants, nitrogen plays a very important role.
