Who demonstrated that photosynthesis is essentially a light dependent reaction in which hydrogen from a suitable oxidisabie compound reduces carbon dioxide to carbohydrates·?

Which of the following statements is/ are correct ? (i) All green plants can prepare their own food. (ii) Most animals are autotrophs. (iii) Carbon dioxide is not required for photosynthesis. (iv) Oxygen is liberated during photosynthesis. Choose the correct answer from the options below:

Assertion : CO_2 is utilized in dark reaction of photosynthesis. Reason : CO_2 as one of the raw material enters the leaves through stomata.

Which of the following are incorrect? A. Plant seeds develop in ovule which itself usually becomes the fruit. B. Plants produce flowers in order to make seeds, so that their species can propagate, C. Just as roots of some plants store food, they may also have nodes, internodes and buds. D. For photosynthesis, leaves take in carbon dioxide and water from soil to release oxygen in air.

During the light dependent reactions of photosynthesis (photophosphorylation) light energy is converted to the chemical energy through the process of chemiosmosis in the chloroplast. Which of the following statement is false?
