关键区别 - 吸收vs渗透

Molecules move from one area to another area by different processes. Imbibition,扩散and osmosis are three methods involved in plants in the molecule movement. Imbibition is the process of absorbing water by a solid substance. These solid substances are known as imbibants, and they are亲水性。渗透is a process where the water molecules move from high water potential area to low water potential area across a semi-permeable membrane. It is a type of passive process driven due to the gradient of the water potential. Both processes are very important for plants. The关键区别在吸收和渗透之间吸收不需要半渗透膜，而渗透是通过半渗透膜发生的。

什么是吸收？

吸收是通过固体物质吸收水而不形成溶液的过程。该物质被称为无限，这些物质不会溶于水中。含量应该是亲水性的。他们不应排斥水分子。

图01：种子发芽

Dry seeds are a good example for imbibant. For the发芽目的，它吸收了环境中的水。不同的含水表现出不同的吸收水的能力。蛋白质表现出良好的敏捷能力淀粉和纤维素。Due to this reason, proteinaceous seeds show more swollen nature than starchy seeds. This process is very important for plants mainly because of two reasons. They are the absorption of water from the soil by the细胞壁根毛细胞和种子发芽。这两个过程都通过吸收发生。

什么是渗透？

渗透is the process of water movement from a region of higher water potential to a region of low water potential via a semipermeable membrane. Osmosis is a type of diffusion process. It is a passive process meaning it does not require energy. It is driven by the water potential gradient across the semipermeable membrane. Osmosis is two types;内膜和外膜病。During the endosmosis, water molecules enter the cell due to low water potential compared to that in the solution outside.

Key Difference Between Imbibition and Osmosis

图02：渗透

在外膜病期间，与外部溶液中的水分子相比，水分子由于细胞内部的高水位而离开细胞。因此，内膜病因turgidity而外膜病是原因质解。内膜和外膜病发生在高渗和低渗溶液分别。

What are the Similarities Between Imbibition and Osmosis?

水分子在两个过程中移动。
两种方法都是分子运动方法的类型。
In both processes, water molecules are absorbed (in the case of osmosis, absorption and release both are possible).
这两个过程对植物都非常重要。
两者都是扩散的类型。

Dif是什么ference Between Imbibition and Osmosis?

吸收与渗透
吸收是指通过固体物质吸收水的过程。	渗透是通过半渗透膜从高水电位面积到低水电位面积的流动过程。
Involvement of a Solid Substance
Imbibition involves a solid substance.	渗透不涉及固体物质。
半渗透膜参与
吸收不涉及半渗透膜。	渗透is involved with a semi-permeable membrane.
Requirement of Colloidal Particles
Imbibition requires colloidal particles.	渗透不需要胶体颗粒。它需要溶质颗粒。
Heat Generation
Imbibition can generate heat during the imbibitions.	渗透不会产生热量。
压力发展
High pressure can be developed during the imbibitions.	与吸收相比，渗透不会产生高压。
类型
Imbibition has no types.	渗透有两种类型。内膜和外膜病。

Summary – Imbibitionvs渗透

吸收和渗透是两个促进植物水运动的过程。通过亲水性固体物质吸收水分子被称为吸收。吸收在种子发芽和根毛吸水中非常重要。这些物质被称为吸水物，它们吸引了水分子。但是，含水不会溶解在水中。渗透是涉及水流动的另一个过程。水分子从高水位的区域通过半渗透或选择性膜转移到低水电位的区域。水分子进出细胞的运动是通过渗透发生的。可以通过两种方式解释。内膜和外膜病。 Imbibition does not occur via a semi-permeable membrane. But osmosis occurs via a semi-permeable membrane. This is the difference between imbibitions and osmosis.
