Which of the following is NOT a stage of plant growth?

Photosynthesis is indeed not a stage of plant growth; rather, it is a crucial process that plants undergo throughout their life cycle. During photosynthesis, plants convert light energy into chemical energy by utilizing carbon dioxide and water to produce glucose and oxygen, which supports their growth and development.

In contrast, the other options represent distinct and recognized stages in the plant growth cycle. The seedling stage signifies the early development of the plant from a seed, where it begins to establish roots and leaves. The vegetative stage involves the growth of stems, leaves, and overall mass, where the plant focuses on expanding its structure to gather more sunlight for photosynthesis. Finally, maturity refers to the stage when the plant has reached its fullest growth potential, often marked by the ability to reproduce through flowering or seed production.

Understanding the differentiation between these stages and processes is essential for effective plant management and cultivation.
