The following points highlight the top five experiments on permeability. The experiments are: 1. Effect of Temperature on Permeability (Thermal Death Point) 2. Permeability of Different Dyes through Cell Membrane 3. Experiments on Differential Permeability of a True Solution and a Colloidal Solution 4. Impermeability of Seed Coat 5. Effect of Lons on Permeability and Their Antagonism. Experiment # 1 [...]
Let us make an in-depth study of the ultrastructure and functions of a typical eukaryotic plant cell. A typical eukaryotic plant cell is usually spherical, polyhedral, box-like or elongated in shape with a diameter of about 0.01 mm to 0.1 mm. It consists of three parts: (A) Cell Wall (B) Cytoplasm, and (C) Nucleus. Cytoplasm and the nucleus together are [...]
Read this article to learn about the role of nitrogen in the life of the plants and different sources of nitrogen to plants. Role of Nitrogen in Plants: Nitrogen is a universally occurring element in all the living beings. Apart from water and mineral salts the next major substance in plant cell is protein (about 10-12% of the cell). These [...]
