FLASHCARD QUESTION

Front

What are biofertilizers?

Back

Biofertilizers add nutrients to the soil through natural processes such as fixing atmospheric nitrogen, solubilizing phosphorus, and enhancing plant growth.

2.

FLASHCARD QUESTION

FLASHCARD QUESTION

Front

What are nitrogen-fixing biofertilizers?

Back

Nitrogen-fixing biofertilizers are organisms that can fix atmospheric nitrogen, making it available to plants.

4.

FLASHCARD QUESTION

Front

What are free-living nitrogen-fixing bacteria?

Back

Free-living nitrogen-fixing bacteria, such as Azotobacter and Clostridium, live freely in the soil and fix nitrogen.

5.

FLASHCARD QUESTION

Front

What is associative symbiosis in nitrogen-fixing bacteria?

Back

Associative symbiosis refers to bacteria that live both inside and outside the root, forming a symbiotic relationship with the host plant.

6.

FLASHCARD QUESTION

Front

What are symbiotic nitrogen-fixing bacteria?

Back

Symbiotic nitrogen-fixing bacteria, like Rhizobium, develop a mutually beneficial relationship with leguminous plants, providing them with fixed nitrogen.

7.

FLASHCARD QUESTION

Front

What role do Rhizobium play in nitrogen fixation?

Back

Rhizobium forms nodules on the roots of legume plants, where they fix atmospheric nitrogen in exchange for shelter and food.
