Bacterial Interactions in Plant Defense

Plants naturally produce organic acids with a pH similar to apples, which help maintain their health. When under attack by infections, plants increase acid production from their roots, attracting beneficial bacteria. These bacteria bind to the roots and activate the plant's defense mechanisms, enhancing gene activity to protect against diseases and minimize damage.

What is the pH level of the organic acids produced by plants compared to?

• Apples

• Bananas

• Lemons

• Oranges

What happens to the acid production of plants when they are under attack?

• It stops completely

• It increases sevenfold

• It remains the same

• It decreases

Why do plants increase acid production during an attack?

• To change soil pH

• To repel insects

• To produce more fruit

• To attract bacteria

What role do bacteria play when they bind to plant roots?

• They change the plant's color

• They increase plant growth

• They trigger plant defense responses

• They consume the plant

How do bacteria help plants when they are under attack?

• By blocking sunlight

• By producing more acid

• By activating defense genes

• By providing nutrients
