What is cambium responsible for in plants?

• A. Photosynthesis
• B. Growth
• C. Storage of nutrients
• D. Water absorption

Answer: (B)

Cambium is a layer of generative tissue found in plants that plays a crucial role in growth. Specifically, it is responsible for the secondary growth of stems and roots, allowing plants to increase in girth. This occurs as the cambium produces new cells that differentiate into either xylem (wood) or phloem (the tissue responsible for transporting nutrients and sugars).

While photosynthesis, nutrient storage, and water absorption are vital functions in the life of a plant, they are primarily associated with other structures and tissues. For example, photosynthesis takes place predominantly in the leaves via chloroplasts, nutrient storage often occurs in roots or in other tissues, and water absorption mainly happens through root hairs. The cambium's specific function of facilitating growth through cell division and tissue formation makes it essential for the overall development and structural integrity of the plant.
