Which of the following best defines necrosis in plants?

The correct definition of necrosis in plants is the death of tissue. This condition is often a result of several factors, including disease, environmental stress, or damage from pests and chemicals. Necrosis can manifest in various ways, such as browning, wilting, or the formation of lesions on the plant. When plant tissues undergo necrosis, they lose their ability to function properly, which can negatively impact the overall health and vitality of the plant.

Understanding necrosis is essential for managing plant health, as recognizing the signs can help in diagnosing underlying issues that may need to be addressed through cultural practices, pest management, or other interventions. This concept is particularly crucial in forestry and agriculture, where maintaining plant health is vital for productivity and ecosystem balance.
