9 Questions
What is the purpose of the plant's hypersensitive response?
To recognize and destroy pathogens
What is the primary defense mechanism used by plants to protect themselves from invading organisms?
Hypersensitive response
What is a plant's defense mechanism against invading pathogens?
Producing proteins that can recognize and destroy the pathogen
What is one way that plants defend themselves against pathogens?
Cell walls
What is the result of the plant's hypersensitive response?
The plant cell is destroyed
What is the result of a plant undergoing a hypersensitive response?
The cell being destroyed
What proteins can affect the cells outside of the plant?
Proteins produced by the pathogen
What type of defense mechanism do mammals use to target and destroy pathogens?
Specific defense mechanisms
What is the result of the plant's hypersensitive response?
The cell is destroyed
Study Notes
- Plants use nonspecific defense mechanisms such as the swelling of the skin to kill any invading organisms.
- Specific defense mechanisms are used by mammals to target and destroy pathogens that have invaded them in the past.
- Plant cells have a hypersensitive response which allows them to sense when a pathogen is invading them and they also have cell walls to protect them.
- When a plant is invaded, it produces a dramatic hypersensitive response that can kill the bacteria attacking it.
- Pathogens produce proteins that invade plant cells and cause them to die.
- The plant's defense mechanism is to produce proteins that can recognize and destroy the pathogen.
- If the pathogen and the plant's proteins match, the plant will undergo a hypersensitive response that results in the cell being destroyed.
- Pathogens also produce proteins that can affect the cells outside of the plant.
This quiz will test your knowledge of how plants use nonspecific defense mechanisms to protect themselves from invading organisms. You will be asked about specific defense mechanisms used by mammals, and then asked to compare and contrast the two.
