Difference Between Radicle and Plumule

钥匙差 - 梯形vs Plumule

All seeds containembryos. Seed embryo creates a new plant aftergermination. Therefore, the embryo is protected inside the seed by a hard covering called testa. The seed begins to grow when the right conditions are found such as moisture, warmth, sunlight, nutrient-rich soil etc. There are two main components of a plant; shoot and root. Stem, leaves and roots develop from different parts of the seed embryo. The radicle is the first part that emerges from the seed during the germination through the micropyle (seed pore). It makes the roots of the new plant. Plumule emerges after the radicle and makes the stem of the new seedling.Cotyledons形成幼苗的第一批叶子。这key differencebetween radicle and plumule is thatradicle is the root forming part of the seed embryo while plume is the stem forming part of the seed embryo.种子胚胎的子叶固定粒度和羽流。

What is Radicle?

这radicle is the embryonic root of the plant. It is a part of the seedling that comes first from the seed during the germination. It comes out from the seed through the micropyle. Radicle grows downwards into the soil. A root cap protects the tip of the radicle. It absorbs water and nutrients and supplies to the leaves for startingphotosynthesis. Embryonic stem or the低尾基is found above the radicle.

Radicle emerges from the seed as a short white structure. It is the first root of the new plant. The radicle is negatively phototrophic and positively geographic. And also it is positively hydrotrophic. It is the first part that functions in new plant development.

什么是羽？

Plumule is the part of seed embryo that develops into the shoot after germination. It makes mainly the stem of the plant, and it bears immature leaves. This part performs the photosynthesis and makes new food for the growth and development of the new plant. Plumule is positively phototrophic; hence, it grows towards the sunlight. Sunlight is essential for the photosynthesis of the new shoot.

胚芽和羽属与胚胎的子叶相连。李子位于子叶上方。在epigeal germination，李子与子叶一起生长在土壤表面上方。

What are the Similarities Between Radicle and Plumule?

• 梯形和羽型是种子胚胎的两个主要部分。
• 两者对于新的植物开发都很重要。
• 这两个部分都是diploidin染色体数字。
• 这两个部分都加入了子叶。

摘要 - 粒度vs Plumule

After the fertilization of asperm cell and an egg cell, azygote形成了。合子划分mitosis并形成一个胚胎。胚胎在种子内得到保护，当种子发芽时，它会发展成新植物。胚胎包含几个部分，形成了生长幼苗的不同部分。当满足适当条件时，种子开始发芽。胚胎有营养的滋养，它开始成为一种新植物。从种子到种子孔出现的第一部分称为梯形。梯形是幼苗的第一个根。辐射转化为根，并吸收水和养分为其他部分提供。其次，出现了一个称为羽流的结构。羽型是形成植物茎的胚胎部分。 Cotyledons convert into first leaves of the plant. This is the difference between radicle and plumule.
