A) phototropism
B) photoperiodism
C) photosynthesis
D) Photorespiration
Correct Answer: D
Solution :
Peroxisomes, isolated by Tollbert and termed by de Duve are small spherical bodies having single unit membrane. They are found in the plants in which photorespirarion takes place i.e., a process which involves oxidation of organic compounds by oxygen without producing ATP. Photoperiodism is the response, as affecting growth, reproduction etc, of a plant or animal to the length of exposure to light in a 24 hour period. Photosynthesis is the synthesis of complex organic materials, especially, carbohydrates, from carbon dioxide, water and inorganic salts using sunlight as the source of energy and with the aid of a catalyst, as chlorophyll. Phototropism is the reaction of plants to light in which the plants bend toward the light.Plant response to light by unequal growth caused by concentration of the plant hormone.
