Step 1
What is meant by the dormancy of seeds?
Answer
Dormancy of seeds refers to a period of reduced metabolism or activity, often characterized by a halt in growth and development. This state allows seeds to survive adverse environmental conditions until conditions are more favorable for germination.
Step 2
Step 3
Suggest one way in which a knowledge of dormancy is useful to farmers and gardeners.
Answer
Farmers and gardeners can utilize their knowledge of seed dormancy to time their planting more effectively, ensuring that seeds germinate when environmental conditions are most favorable for crop growth.
Step 4
Water, oxygen and a suitable temperature are all required for the germination of seeds. In the case of each of these factors describe its effect on the process of germination.
Answer
Water is essential for enzyme activity, aiding in the breakdown of stored nutrients for the seedling and facilitating the transport of materials. Oxygen is critical for aerobic respiration, which provides the energy needed for growth. A suitable temperature ensures optimal enzyme activity and overall metabolic processes that support germination.
Step 5
