Which nutrient is essential for proper cell division in plants?

The correct answer, potassium, plays a crucial role in various physiological processes within plants, one of which is cell division. Potassium is involved in regulating osmotic pressure and maintaining turgor pressure in cells, which are essential for the growth and development of plant tissues. It acts as a cofactor for many enzymes and is vital for the synthesis of nucleic acids and proteins, both of which are essential for cell division.

Potassium also helps in the movement of nutrients and water within the plant, ensuring that cells receive the necessary components for division and growth. A deficiency in potassium can lead to impaired cell division, resulting in stunted growth and overall poor plant health. Thus, its role in cell division underscores its importance as an essential nutrient for proper plant development.
