Vedclass · Answer

(D) Light is a critical environmental factor that influences many physiological processes in plants.$1$. Flowering is regulated by photoperiodism,which is the response of plants to the duration of light and dark periods.$2$. Photosynthesis is directly dependent on light energy to convert carbon dioxide and water into glucose.$3$. Transpiration is influenced by light because light triggers the opening of stomata,which increases the rate of water loss.$4$. Fertilization,which involves the fusion of male and female gametes within the embryo sac,is an internal process that is not directly triggered or regulated by light intensity or duration. Therefore,it is the correct answer.

Which one of the following events in a botanical garden is never directly influenced by light?
