A bean seed shrinks and disappears after the seedling develops leaves because the seed's food reserves are used up. Since the leaves can now make energy for the plant, this lack of food reserves from the seed is not a danger.

∙ 9y agoMost seeds have two bean-shaped structures called the seed leaves or cotyledons. When the seed receives sufficient moisture, light and air, it becomes soft and spongy. The seed coat breaks and baby plant or embryo comes out. The baby plant develops roots and shoot. Cotyledons store food for the baby plant or embryo to grow. When tiny leaves open on the shoot and begins to make food. This young plant is called a seedling. The seedling absorbs water and nutrients from the soil with the help of its roots. As the plant grow in size, it develops more leaves and start making its own food. At that time the cotyledons shrink and disappear and seedling then grow to become a new plant.
