Cankers refer specifically to sunken areas on trees where the bark is dead, often caused by disease or environmental factors. This condition typically develops in response to infections, such as bacterial or fungal pathogens, leading to localized areas of necrosis. Over time, these cankers can disrupt the flow of water and nutrients within the tree, potentially leading to more severe health issues for the plant. Understanding cankers and their implications is crucial for managing tree health effectively.

The other options describe unrelated characteristics of trees. Bright flowers are a distinct feature but do not correlate with the definition of cankers. Pests affecting tree roots focus on a different aspect of tree health and do not describe the physical injury represented by cankers. Leaf patterns might allude to a variety of leaf anomalies or traits but are also not relevant to the definition of cankers.
