Which of the following describes the impact of excessive water on a plant?

Excessive water in a plant can lead to stress and the development of various disorders. When a plant receives too much water, it can become waterlogged, which affects its root health and overall ability to absorb necessary nutrients and oxygen. This anaerobic condition can result in root rot, reduced growth, and vulnerability to disease. Additionally, excessive moisture creates an environment conducive to certain fungal infections and can lead to nutrient imbalances, compounding stress factors on the plant.

In contrast, the other options do not accurately reflect the effects of too much water. Increased disease resistance is more commonly associated with healthy, well-maintained plants rather than those suffering from excess water. Growth acceleration may occur temporarily under optimal watering conditions, but excessive watering typically hampers growth due to root suffocation. Lastly, excess water does not inhibit bacterial growth; rather, it often promotes conditions conducive to bacterial proliferation. This further illustrates the negative implications of overwatering on plant health.
