关键的区别——植物生长在光明与黑暗
光合作用是一个由包含植物引发的过程chlorophyll。由于存在阳光而发生的过程。因此,植物适应在不同的光强度下生长。Plants that生长在高光强度下higherrate of photosynthesisare referred作为在光中生长的植物whileplants that grow under low light intensities or dark conditions with a lower rate of photosynthesis arereferred作为种植的植物in the dark。这是关键区别between plants grown in light and dark.

What are Plants Grown in Light?
绿色植物的主要目标是光合作用。他们利用阳光和一种称为叶绿素的特殊色素分子。叶绿素分子将捕获落在叶子表面的光。光的不同波长将影响光合作用的速率。因此,阳光是一个重要方面。在光条件下生长的植物的背景下,植物体是通过适应性发展而开发的,以最大程度地接收阳光。植物的叶子以角度开发,以暴露并捕获到更高浓度的光强度。
The structure of the leaves of plants grown under light conditions possesses different adaptations to conserve the water levels and prevent excessivetranspiration and evaporation。These adaptations are; smaller leaf size with a lesser surface area, thick leaves and cuticle and the presence of 2-3 cellular layers of palisade tissue layer. The plants grown under light conditions will contain leaves with a less surface area. This is to prevent the rate of transpiration and to preserve the water content in plants. Broader leaves with a larger surface area would be exposed to sunlight more, and eventually facilitate the transpiration and evaporation in higher quantities.
叶子的厚度也有助于这一方面。在光中生长的植物具有较厚的叶肉层,并具有2-3个帕利塞德细胞层。他们拥有一个较短的节点。在叶绿体排列的背景下,大多数叶绿体都排列在叶片的帕利塞德层中。这些植物不会在短时间内枯萎。
What are Plants Grown in Dark?
Not all plants grow under light conditions. Some plants prefer less light intensities. Therefore, the structure and function of such plants differ from plants that grow under high light intensities. It is confirmed that light is an essential factor in the process of photosynthesis. Plants that grow under dark conditions might or might not initiate photosynthesis. They are adapted to perform photosynthesis under very low light intensities. Structural features of the plants (especially the leaves where photosynthesis takes place) are altered from a typical plant and is adapted to the environmental conditions that enable the plant growth.
在黑暗条件下生长的植物具有更薄的角质层。与在光条件下生长的植物相比,叶子的厚度也较小。这主要是为了促进低水平的阳光渗透到叶子中。这些植物的叶绿体在两个叶肉层中均匀排列。栅栏和海绵。帕利塞德层是一个细胞层厚。这些植物的节间是长的,叶子的大小相对较大,表面积较高。这是为了确保叶子在低光强度下接收更多的阳光。在黑暗条件下生长的植物的叶子迅速枯萎。
在光和黑暗中生长的植物之间有什么相似之处?
- Both contain chloroplasts.
- 两者都可以光合使用。
What is the Difference Between Plants Grown in Light and Dark?
植物在光线下生长vs Plants Grown in Dark |
|
在高光强度下生长的植物被称为在光中生长的植物。 | Plants that grow under low light intensities or dark conditions are known as plants grown in the dark. |
Leaves | |
Leaves are small and thick. | 叶子的尺寸相对较大且薄。 |
节日 | |
Plants grown in light have short internodes. | 在光线下生长的植物具有更长的节间。 |
补偿点 | |
Plants grown in light have high compensation point. | 在黑暗中生长的植物的补偿点很低。 |
叶绿体的位置 | |
Most of the chloroplasts are found in the palisade layer of the leaf in plants grown in light. | Chloroplasts are distributed evenly among the two mesophyll layers; palisade and spongy. |
表皮 | |
Plants grown in light have thick cuticle to prevent excessive transpiration. | 在黑暗中生长的植物相对薄。 |
Palisade Layer | |
Palisade layer contains 2-3 cellular layers in plants grown in light. | 在黑暗中生长的植物中只有一个细胞层在栅栏层中。 |
枯萎 | |
The wilting process is slow in plants grown in light. | 叶子会在黑暗中生长的植物中迅速枯萎。 |
支持 | |
高级语言有更多的社区支持。 | Low Level Languages do not have much community support. |
概括 -植物在光线下生长vs Dark
植物光合作用及其光合作用速率主要取决于光的强度。在高光和弱光条件下生长的植物表现出不同的适应光合作用及其正常生长代谢。在光条件下生长的植物叶片的结构具有不同的适应性,以节省水位并防止过度蒸腾和蒸发。与黑暗中生长的植物相比,它们的叶子较厚。这是为了防止通过蒸腾作用并促进光在光明和黑暗中生长的植物中渗透到植物中。两种类型都包含用于光合作用的叶绿体和叶绿素。这可以描述为在光和黑暗中生长的植物之间的差异。
