Answer:
1.
Did you mean: What will happen to seeds of cotton wool is dry?
Answer: Seeds need moisture to germinate into new plants. If the cotton wool had been left dry, then the seeds would not have received enough moisture. As a result, germination would not have been possible. ... Some of the seeds were not able to get enough water, air and warmth to grow into small plants
2.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.
3.One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of gravity) and roots go down (in the same direction as the force of gravity).
4.Trees will grow their branches in the direction that receives the most sun. This means that trees will have more branches on the south facing side since it is exposed to the most sunlight throughout the day.06-Aug-2020
