Question

Which of the following are raw materials for photosynthesis?
A. Oxygen and ATP
B. Water and carbon dioxide
C. NADP and hydrogen
D. Glucose and oxygen
E. Carbohydrates and NADP
F. Carbon dioxide, water, and sunlight

Answer 1

Hint: It is a process of conversion of light energy into chemical energy that helps in the preparation of food in plants to give them nutrition and fulfill their mineral requirements.

Complete answer:
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. In most cases, oxygen is also released as a waste product.

Additional Information:
-Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs.
-Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth’s atmosphere and supplies most of the energy necessary for life on earth.
-The process of photosynthesis always begins when energy from light is absorbed by proteins called reaction centers that contain green-colored pigment chlorophyll.
-In plants, these proteins are present inside organelles called a chloroplast.
-In these light-dependent reactions, some energy is used to strip electrons from water, producing oxygen gas.
-The three main stages of photosynthesis are:
a)Harvesting Radiant Energy - the plant absorbs light with the help of chloroplast.
b)Converting Radiant Energy – the plant converts light energy into a usable form of chemical energy to fuel the plant’s cells.
c)Storing Radiant Energy – plants use carbon dioxide and water from the soil to convert ATP and NADPH, resulting in the production of sugar, fatty acids, and glycerol.

So, the correct answer is ‘Carbon dioxide, water, and sunlight'.

Note: The term photosynthesis originated from a Greek word phos meaning light and synthesis meaning putting together. The first photosynthetic organisms probably evolved early in the evolutionary history of life and most likely used reducing agents such as hydrogen or hydrogen sulfide, rather than water, as sources of electrons. Photosynthetic organisms also convert around 100-115 billion tons of carbon into biomass per year.
