|
|
It helps to release the energy needed by the embryo to grow.
|
|
|
It causes the seed to swell and break its seed coat, allowing the embryo to expand and grow.
|
|
|
It speeds up the chemical reactions that take place in the seed.

None of the above

Detailed explanation-1: -Temperature influences the moisture content, hormone function, and enzyme activity that occurs during seed germination. Warm temperatures accelerate the chemical reactions in seeds and accelerate cell formation for development.
Detailed explanation-2: -Temperature affects germination in three primary ways: moisture, hormone production, and enzyme activity. For seeds to germinate, they need to imbibe water. For this to occur, sufficient moisture must be present. A warmer climate may increase evaporation and decrease moisture, which would negatively affect germination.
Detailed explanation-3: -Karrikins stimulate seed germination and influence seedling growth. They are active in species not normally associated with fire, and in Arabidopsis they require the F-box protein MAX2, which also controls responses to strigolactone hormones.
