Mycorrhiza is a mutualistic symbiotic relationship between certain fungi (mycorrhizal fungi) and the roots of most vascular plants. In this relationship, the fungus provides essential nutrients, particularly phosphorus and nitrogen, to the plant, while the plant provides the fungus with carbohydrates produced through photosynthesis. This mutually beneficial interaction is an example of a symbiotic relationship.
So, the correct option is (A): Symbiotic relationship
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
A full wave rectifier circuit with diodes (\(D_1\)) and (\(D_2\)) is shown in the figure. If input supply voltage \(V_{in} = 220 \sin(100 \pi t)\) volt, then at \(t = 15\) msec:
A constant voltage of 50 V is maintained between the points A and B of the circuit shown in the figure. The current through the branch CD of the circuit is :
Fungi (singular: fungus or funguses) are eukaryotic organisms classified under the kingdom Fungi. These organisms can be single-celled or multicellular. They include organisms, particularly yeasts, mushrooms, and molds. The eukaryotic microorganisms possess a cell wall made of chitin and polysaccharides. With that, they can be found anywhere and are classified as heterotrophs.
The nucleus they keep is surrounded by a nucleus membrane and is dense, clear, and also contains chromatin threads. The existence of fungi can be seen as black spots found on bread, mushrooms, and yeast cells. These microorganisms are also responsible for fungal and skin diseases.
