Symbiotic nitrogen fixation in non-leguminous plant is carried out by A. Azotobacte... | Snapsolve

Summary

The video explains the concept of symbiotic nitrogen fixation in plants. It focuses on how certain plants, particularly those in the legume family, engage in a mutualistic relationship with nitrogen-fixing bacteria. These bacteria, residing in root nodules, convert nitrogen into a usable form for the plant, while benefiting from the reduced compounds in return. The video specifically highlights how this process occurs in plants like the money plant, where both the plant and the bacteria benefit from the exchange. The correct answer to the quiz question regarding which plants carry out this process is option D.

Takeaways

• 😀 The question addresses symbiotic nitrogen fixation in plants, focusing on their interaction with bacteria.
• 😀 The concept of symbiosis is explained, where plants and bacteria benefit each other.
• 😀 Nitrogen-fixing bacteria, part of the symbiotic relationship, reside in the root nodules of plants.
• 😀 The specific plants being referred to are from the legume family, known for hosting nitrogen-fixing bacteria.
• 😀 The bacteria in the root nodules convert atmospheric nitrogen into a form usable by the plants.
• 😀 This process is essential for the plants' growth, as nitrogen is a key nutrient.
• 😀 The bacteria, in turn, receive reduced carbon compounds from the plant as a reward for their nitrogen fixation.
• 😀 The root nodules, where this process occurs, are not typically colored, indicating the lack of chlorophyll in them.
• 😀 The symbiotic relationship between plants and nitrogen-fixing bacteria is a clear example of mutual benefit in nature.
• 😀 The correct answer to the question about which plants perform symbiotic nitrogen fixation is option D, which involves the specific plant under discussion (likely a legume).

Q & A

What is symbiotic nitrogen fixation?

Symbiotic nitrogen fixation is a biological process in which certain plants, in partnership with specific bacteria, convert atmospheric nitrogen into a form that the plant can use. This process happens in the root nodules of the plant.

Which bacteria are involved in symbiotic nitrogen fixation?

The bacteria involved in symbiotic nitrogen fixation belong to a specific family, and they live in the root nodules of plants. They play a key role in converting nitrogen from the atmosphere into a form the plant can utilize.

Where does nitrogen fixation take place in plants?

Nitrogen fixation occurs in the root nodules of plants, where bacteria live and convert atmospheric nitrogen into a usable form for the plant.

What do bacteria gain from the symbiotic relationship with plants?

The bacteria benefit from the plant by living in its root nodules, where they receive nutrients and a stable environment to thrive.

What benefits do plants receive from the symbiotic relationship with bacteria?

The plant benefits by receiving nitrogen from the bacteria, which is essential for its growth. The bacteria fix nitrogen from the atmosphere and convert it into a form that the plant can use.

What is the significance of root nodules in nitrogen fixation?

Root nodules are specialized structures in plant roots where bacteria live and carry out nitrogen fixation. These nodules provide the environment necessary for the bacteria to convert nitrogen into a form usable by the plant.

What is the relationship between plants and bacteria in nitrogen fixation?

The relationship between plants and bacteria in nitrogen fixation is symbiotic. Both organisms benefit: the plant receives nitrogen, while the bacteria gain nutrients and shelter from the plant.

Which plant is mentioned as an example of symbiotic nitrogen fixation in the script?

The script refers to a plant that is part of a family that includes money plants, which engage in symbiotic nitrogen fixation with bacteria.

How does nitrogen fixation benefit both the plant and the bacteria?

Nitrogen fixation benefits the plant by supplying it with nitrogen, a key nutrient for growth. The bacteria benefit by obtaining reduced carbon compounds from the plant, which are essential for their survival.

What is the correct answer to the question of which plant engages in nitrogen fixation according to the script?

According to the script, the correct answer is Option D, which refers to a plant involved in the symbiotic nitrogen fixation process.
