The ultrastructure of cotyledon cells is described at five stages of lupin seed development, distinguished on the basis of their morphological features. It was found that the endoplasmic reticulum nad dictyosomes participate in the synthesis and transport of storage protein, and that protein is deposited in the central vacuole or in newly forming ones. In the investigated zone of lupin cotyledon cells two forms of protein bodies were observed differing in the contrast and compactness. Both were the simple protein, bodies. Parallelly to storage protein synthesis, thickening of the cell walls was observed which may indicate synthesis and deposition of hemicellulose in them. Storage lipids surrounding the protein bodies form in the end stages of seed development
