synergid

1. The persistent synergid may still have a synthetic function as its cell wall becomes thick and lipids occur.
   因宿存助细胞壁变厚，细胞质内出现脂滴，宿存助细胞可能仍有合成功能。
2. The cell wall surrounds the cell, but its chalzal ends and the lateral wall with synergid is discontinuous.
   细胞外被细胞壁，其合点端及侧方与助细胞共同壁不连续。
