In prophase I meiocyte plastids and mitochondria were situated at random. By telophase I plastids and mitochondria were aggregated in an equatorial plane. The aggregation was differentiated into three layers, the middle layer formed mostly by mitochondria, the outer layers consisted largely of plastids. By telophase II the mitochondria layers separated the cell into four domains, while plastid layers were disaggregated. Inside the mitochondrial layer the cell plates were formed. During this process mitochondria layers gradually disintegrated. During prophase I to telophase I numerous plastids seemed to undergo divisions. The telophase I layer mitochondria seemed to give rise to small electrolucent vesicles
