Chlorine primarily helps in:

Chlorine plays a critical role in maintaining the ionic balance within plant cells. It is an essential micronutrient that helps facilitate the movement of nutrients and water within the plant by maintaining osmotic balance and regulating the opening and closing of stomata, which are crucial for gas exchange. This balance is vital for proper cellular function, as it influences processes such as photosynthesis, respiration, and overall plant health.

While other factors relate to plant growth and resistance, they are impacted by various nutrients and environmental factors rather than being a primary function of chlorine. Strengthening root systems, increasing disease resistance, and enhancing flower production are influenced by other nutrients, such as phosphorus, potassium, and nitrogen, rather than chlorine directly.
