between the sub-leaf and the first
piece of the real leaf) and the lower embryo shaft (the part between the sub-leaf and the root); Developed into stems and leaves, so it is the undeveloped ground branch; the child leaves are the leaves of the young embryo, the seeds of the bee plant have one (single leaf plants, such as rice, wheat, etc.), there are two (twin leaf plants, such as soybeans, etc.), the seeds without endosperm, the leaves are rich in nutrients.
