AP BIOLOGY

Detailed explanation-1: -Answer: Solution: Only living seeds can germinate which require optimum conditions like moisture, oxygen and temperature. Create a simillar illustration where the three seeds are clearly.

Detailed explanation-2: -All seeds need water, oxygen and the right temperature to germinate. Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth. Some Australian plants need fire or smoke to germinate, while others rely on insects and animals.

Detailed explanation-3: -Each plant has a specific optimum and a range within which germination will occur. The closer the temperature is to optimum, the quicker germination will occur. Most seeds germinate when the soil temperature is between 68° and 86°F.

Detailed explanation-4: -Seeds remain dormant or inactive until conditions are right for germination. 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.

Detailed explanation-5: -(i) Seeds need moisture (water) and air for sprouting. If the seeds do not get the right amount of moisture and air they will not sprout at all. (ii) Seeds spread to far places as they are carried away by birds, animals, air and water from one place to another place.
