常见错误

❌ 错误:The chloroplast is a part of animal cells.
✓ 正确:The chloroplast is a part of plant cells.

错误:叶绿体只存在于植物细胞中,动物细胞没有叶绿体。正确用法应指定为植物细胞。

❌ 错误:Chloroplast do photosynthesis.

chlorophyll 是叶绿素,一种色素,存在于叶绿体中;chloroplast 是含有叶绿素的细胞器。chlorophyll 更具体指化学物质,chloroplast 指结构。

Chlorophyll gives chloroplasts their green color, but the chloroplast itself is an organelle.

plastid

plastid 是质体,一类细胞器,包括叶绿体、白色体等;chloroplast 是质体的一种,特指进行光合作用的绿色质体。plastid 更泛指,chloroplast 更特指。

All chloroplasts are plastids, but not all plastids are chloroplasts; some store starch instead.
