Function of Seed Leaves in Bean Germination

When it comes to the function of the seed leaves (cotyledons) in the germination of a bean, it's important to understand their role in the process. The seed leaves of a bean perform a crucial function during germination, aiding in the initial growth and development of the emerging seedling.

The correct answer to the question is: 2) эндосперм

The seed leaves, or cotyledons, in a bean seed serve as a source of nutrients for the developing seedling. They provide essential energy and nutrients for the young plant until it can establish its own photosynthetic capabilities. This process is vital for the successful germination and early growth of the bean plant.

The cotyledons also play a role in the absorption of nutrients and water from the surrounding environment, facilitating the initial growth of the seedling. Additionally, they protect the delicate embryonic plant within the seed and aid in the mobilization of stored food reserves to support early growth.
