What is Necrosis?

1. The predators, parasites, and pathogens that attack and kill other organisms.

2. The death of plant or animal tissues.

3. A microorganism causing plant diseases.

4. A pesticide used to control nematodes.

The correct answer is: The death of plant or animal tissues.

Necrosis refers to the death of plant or animal tissues. It is a physiological process that occurs when cells or tissues in a living organism die due to various factors such as injury, infection, or lack of oxygen. This term is commonly used in the field of agriculture and biology to describe the death of plant tissues resulting from factors such as disease, environmental stress, or chemical exposure. The other options are not correct because: A. The predators, parasites, and pathogens that attack and kill other organisms do not specifically refer to necrosis. C. A microorganism causing plant diseases does not directly define necrosis. D. A pesticide used to control nematodes is not a definition of necrosis but rather a method of pest control.
