Answer:
The following are the reasons with explanation
Explanation:
1) The embryo is the fertilised ovule, an immature plant from which a new plant will grow under proper conditions.
2)If all the seeds of a plant fall under the parent plant, there will be shortage of space for the germination of the seeds. Even if they germinate, they cannot grow properly due to scarcity of food resources and also space.
3)Dormant seeds are viable seeds that do not germinate because they require specific internal or environmental stimuli to resume growth. Under proper conditions, the seed begins to germinate and the embryo resumes growth, developing into a seedling.
4)Many plants like Strawberry and Raspberry are propagated by natural layering method. The natural layering occurs because these plants form runner, which are soft horizontal stems running above the ground
