Cotyledon mcsophyll cells in maturing seeds of Gossypium hirsutum from aleurone grains by accumulation of protein and other materials in vacuoles. Globoids and unidentified, electron‐dense particles can be found in the matrix of amorphous protein. As revealed by electron microscopy, the vacuoles appear to communicate with cisternae of endoplasmic reticulum in early stages of development. This paper and many reports in the literature cast doubt on the reported plastid nature of certain aleurone grains.
