At leptotene, the distribution of organelle was polarized. 減數(shù)分裂前，大孢子母細胞的核偏向合點端，核內出現(xiàn)核液泡，細胞器分布均勻，內質網(wǎng)多位于珠孔端。

When autophagy occurs, a double membrane forms around a cell organ, or organelle. 自噬現(xiàn)象出現(xiàn)時，會在細胞或細胞器的周圍形成雙層膜。

The first organelle to be identified was the nucleus. 第一個需要辯認的細胞器官是細胞核。
