This phenomenon can occur even when chemical fixation is conducted in the presence of a cationic dye, if the choice of agent is inappropriate, and also during post-fixation in osmium tetroxide (when the tissue is destined for an ultrastructural analysis in the transmission electron microscope). ...
Stem elongation, flower and seed development, and ripening occur during the second growing season, after which the plant dies. Biennial crop type includes carrots, beets, turnips, onions, cabbage, parsley, and coriander.Perennial PlantsPerennials are plants that can live for more than two growing...
The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This transformation can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation Premium Nitrogen Oxygen 597 Words 3 Pages Good ...
How can such a strain be used to create a transgenic plant? How do rhizomes develop after being planted? What factors influence the development of a plant? What influences the plant development? Is there some kind of immortality in plants? If so, how does this occur, ...
Explain in detail the nitrogen transformation in soil by plants. How do greenhouse gases affect the growth rate of plants? What harmful process can occur due to fertilizer runoff from farms? What is one potential reason for why a plant may experience diminished photosynthetic rates? Describ...
Sulfur deficiencies are often misdiagnosed as nitrogen deficiencies. This is because both help a plant retain its green color. In either of these deficiencies, the main symptom is yellowing, chlorotic leaves. However, details are key when diagnosing issues that occur with plants. ...
