  1. View Hint View Answer Discuss in Forum

    Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as a side-effect. It is an anaerobic process since Yeasts perform this conversion in the absence of oxygen.

    Correct Option: B

    Fertilization in plants is not directly influenced by sunlight. It occurs when pollen grains are transported from anthers to stigma. When ripe pollen from an anther catches on the stigma of the same kind of flower, each pollen grain sends out a small threadlike tube. Fertilization occurs after pollination, when pollen grains land on the stigma of a flower of the same species. During this time, a series of events take place leading to the formation of seeds.
