常见错误

❌ 错误:The endosperm is a part of the flower.
✓ 正确:The endosperm is a part of the seed.

错误:胚乳是花的一部分。正确:胚乳是种子的一部分。解释:胚乳特指种子中的组织,不是花的结构,中文学习者可能混淆植物部位。

❌ 错误:Endosperm can be eaten directly as food.
✓ 正确:Endosperm is processed into food products like flour.

错误:胚乳可以直接作为食物食用。正确:胚乳被加工成面粉等食品。解释:胚乳通常需要加工(如研磨)才能食用,直接食用不常见,中文学习者可能误解其用途。

近义词辨析

cotyledon

cotyledon(子叶)是胚胎的一部分,在发芽后提供营养,而 endosperm(胚乳)是种子中的独立组织,在发芽前储存养分。

Endosperm stores starch for the embryo, while cotyledon emerges during germination to photosynthesize.

perisperm

perisperm(外胚乳)是种子中由珠心发育而来的营养组织,较少见,而 endosperm(胚乳)更常见,由受精过程形成。

In some plants, perisperm persists alongside endosperm, but endosperm is more dominant in angiosperms.
