Plastids and mitochondria comportment in dividing meiocytes of Psilotum nudum

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 plast...

Description
Summary: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 gradualy disintegrated. During prophase I to telophase I numerous plastids seem to undergo divisions. The telophase I layer mitochondria seemed to give rise to small electron-lucent vesicles.
