Question

which experiment will you perform to demonstrate the arrangement of plant cells in the epidermis of the plants​

Answer 1

Answer:

Explanation:

To depict the structure of a plant cell, an epidermal cell of an onion will be used as an example. The epidermis is the final tissue that covers all organs above ground. The cells of the onion epidermis are common specimens on the first day of a German basic botanical course. Since they contain no chlorophyll, they are actually no "typical" plant cells.

The "living" content of a cell, the protoplasm , is surrounded by a membrane called plasma membrane or plasma lemma. The protoplasm is usually next to the cell wall, so that the plasma lemma can hardly be seen. To display it, the cells are transferred into a high salt or sugar solution. As a result the protoplasm shrinks and detaches itself from the wall. The process is reversible and is called paralysis. This behavior is due to the properties of the membrane and the plasma. It is reviewed in more detail elsewhere. A substance that causes paralysis is called cytoplasmic and - depending on its chemical composition (potassium ions or calcium ions, for example) - the protoplasm takes on different shapes. The cytoplasmic has accordingly an influence on the properties of the membrane. The properties of the plasma membrane differ from that of the Elastoplast. The Elastoplast is the membrane that surrounds the vacuole. The difference is especially striking if cells with a colored vacuole content are used. Often the vacuole is crisis-crossed by numerous plasma cords. The plasma cannot therefore not simply be viewed as a solution that is influenced by the rules of hydrodynamics alone. Rather, it contains viscous, structure-determining components, whose chemical, hemispherical and structural properties have only been recognized recently and in fragments.
