What role do seed leaves play in the early development of plants?

• A. They absorb water
• B. They provide initial nutrition
• C. They facilitate branching
• D. They aid in photosynthesis

Answer: (B)

Seed leaves, also known as cotyledons, play a crucial role during the early development of plants by providing initial nutrition. When a seed germinates, the cotyledons serve as the first food source for the developing plant before it can establish a root system and begin photosynthesis. They are typically rich in stored nutrients that supply the necessary energy and materials for the seedling to grow until its true leaves develop and the plant can begin to produce its own food through photosynthesis. Once the true leaves emerge, the cotyledons may either remain as part of the plant or wither away, depending on the plant species. This early nutritional support is vital as it allows the young plant to develop and gain strength to survive in its environment, paving the way for future growth.
