Answer:b
Explanation:some seeds do not germinate during adverse conditions.this is called dormancy.this may occur due to hard seed coat.this seed coat prevents the entry of water and oxygen which are necessary for the plant to grow and germinate.
Water is a nessesary medium for essential metabolic reactions in the seed.the temperature at which is seed would germinate also varies.
Oxygen is needed for a germinating plant to obtain energy through respiration. The seed coat may also be so tough that they resist growth and expansion from taking place.
Seeds are able to break dormancy on their own.some may need to undergo natural processes that lead to softening.this process may be slow.some others may need heat or certain nutrients.
Germination of seed occurs when the dormant plant has taken in water and oxygen to show high metabolic activities leading to the formation of a seedling.
