Answer 1

Answer:

Biology

In order to grow food with a minimum of external inputs, organic producers need to understand much about the biology of plants and ecological

Answer 2

Explanation:

1. They show dispersion either due to wind, air or water. Some animals also disperse the seeds from the plants as the seeds get stuck on some parts of their body n are scattered from one place to the other.
2. We know that seeds need optimal amounts of water, oxygen, temperature, and light to germinate.
3. All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.
4. The process by which land plants produce their own food using sunlight and carbon dioxide is known as photosynthesis (Figure 1). While carbon dioxide is absorbed by the leaves, the sunlight is captured by a chemical molecule in the plant, called chlorophyll (Chl).
5. Possible Causes---Too little nutrients can stunt growth, too much much nutrition can damage the roots and prevent the seedling from taking in water. Low temperatures. Most seeds like a soil temperature of around 65°-75°. Excessive moisture and overwatering.
6. Germination refers to the method by which an associated organism grows from a seed or a reproductive structure. The foremost common styles of germination embrace a seed growing to make a spermatophyte and also the formation of a reproductive structure ling from a spore.
7. All seeds need water, oxygen, and proper temperature in order to germinate. ... Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat. The embryo's cells start to enlarge.
8. In agriculture and gardening, transplanting or replanting is the technique of moving a plant from one location to another.
