Explanation:
A nursery bed can be defined as a specially prepared temporary plot of land or garden which serves as a home for raising seedlings (young plants) prior to planting them in the main location (area). Thus, when older trees in the environment or surrounding dies or are cut-off, these younger plants (trees) propagated in the nursery bed are transferred to replace them.
<em>Some of the criteria or requirements for setting up a nursery bed are;</em>
1. Shed: this is one structure essential in propagating young trees.
2. Location/Site: a place near a source of water should be chosen because water is essential for plant growth and coolness from extreme heat caused by the sun.
3. Storage place for tools and equipment: it is important to have a complete set of tools or their substitute to be able to carry out all nursery activities properly.
4. Boxes, pots, and plots for germinating seeds: there are three places to germinate seeds, young plants, and young trees. Pots are used for germinating young trees while boxes and plots are used for raising seedlings.
5. Soil type: different plants need different types of soil. These includes clay, loamy and sandy soil.
Answer;
The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.
Explanation;
-Photosynthesis is the process by which green plants use light energy from the sun, water and carbon dioxide to make organic molecules, such as simple sugars.
-The process takes place in two phases; light dependent stage and light independent stage.
-During light dependent stage light energy is used to break down water molecules into hydrogen ions and oxygen atoms.
-Light independent reactions uses CO2 and the ATP and NADPH from light dependent reactions to produce sugar/ glucose. ATP is used to provide the energy for sugar synthesis and NADPH is used for electrons in the reduction of Carbon Dioxide into sugar.
