Oxygen from the air and stored food in the seed leaves help to speed up the chemical reactions that take place in the seed.
D
Carbon dioxide from the air causes the seed to swell and break its seed coat, allowing the embryo to expand and grow.
Explanation: 

Detailed explanation-1: -Seeds Need the Right Environment to Germinate Temperature, moisture, air, and light conditions must be correct for seeds to germinate.

Detailed explanation-2: -The process of the growth of a plant (in this case, the seedling) from the seed is called germination. Seeds germinate in the presence of suitable environmental conditions. They require air, water, soil, and sunlight for germination. If a seed is sowed too deep in the soil, it will not germinate.

Detailed explanation-3: -The process of seeds developing into new plants is called germination of seeds. The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.
