Embryo
In the image at left,
the green bracket indicates the seed coat that is being formed from the
inner and outer integuments. The blue bracket indicates the space normally
occupied the embryo and endosperm (not visible in this image).
Embryo LS
In the cross section of the embryo at left, the outer integument appears to be composed of tough lignified cells termed macrosclereids. Remnants of the nucellus, the inner tissue of the ovule, is still present. Endosperm is beginning to form and later will expand to crush the nucellus. This endosperm will serve a nutrient source for the developing embryo.
