SEED LEAF在英语中的意思是什么？

子叶

Cotyledon

子叶是植物种子中胚胎的重要组成部分。 在发芽时，子叶可能成为幼苗的胚胎第一叶。 存在的子叶数是植物学家用于分类开花植物的一个特征。 具有一个子叶的物种称为单子叶植物。 具有两个胚胎叶的植物被称为双子叶植物，并被放置在类Magnoliopsida。 在子叶光合的双子叶植物幼苗的情况下，子叶在功能上类似于叶。 然而，真正的叶子和子叶是发育不同的。 子叶在胚发生过程中形成，连同根和枝条分生组织，因此在萌发之前存在于种子中。 然而，真正的叶片是从芽顶生分生组织后胚胎形成的，这些分生组织负责产生植物的后续地上部分。 草的子叶和许多其他单子叶植物是由盾片和胚芽鞘组成的高度修饰的叶。 盾牌是种子内的专门从相邻胚乳吸收储存食物的组织。

A cotyledon is a significant part of the embryo within the seed of a plant. Upon germination, the cotyledon may become the embryonic first leaves of a seedling. The number of cotyledons present is one characteristic used by botanists to classify the flowering plants. Species with one cotyledon are called monocotyledonous. Plants with two embryonic leaves are termed dicotyledonous and placed in the class Magnoliopsida. In the case of dicot seedlings whose cotyledons are photosynthetic, the cotyledons are functionally similar to leaves. However, true leaves and cotyledons are developmentally distinct. Cotyledons are formed during embryogenesis, along with the root and shoot meristems, and are therefore present in the seed prior to germination. True leaves, however, are formed post-embryonically from the shoot apical meristem, which is responsible for generating subsequent aerial portions of the plant. The cotyledon of grasses and many other monocotyledons is a highly modified leaf composed of a scutellum and a coleoptile. The scutellum is a tissue within the seed that is specialized to absorb stored food from the adjacent endosperm.
