what is wrong among the following statement s regarding photosynthesis. options. a carbon-dioxide and water are nessecary . b chlorophyll is not recessary for photosynthesis. c sunlightbin necessary for photosynthesis. d carbohydrate are formed during photosynthesis.
Answers
Answer:
Option D is wrong. Carbohydrates are not formed sugars are formed
Answer:
(b) Chlorophyll is not necessary for photosynthesis.
Explanation:
Photosynthesis
Photosynthesis is the process that plants and other organisms use to convert light energy into chemical energy, which can then be released through cellular respiration to fuel body functions.
(b) Chlorophyll is not necessary for photosynthesis.
The entire process of photosynthesis takes place in the plant's chloroplasts, which contain a green pigment called chlorophyll. It is a chlorophyll molecule designed to absorb sunlight. Hence, it is essential for photosynthesis.
Therefore, option (b) is correct.
(a) Carbon-dioxide and water are necessary
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. In a plant cell, water is oxidized, meaning it loses electrons, while carbon dioxide is reduced, meaning it gains electrons. It turns water into oxygen and carbon dioxide into glucose.
Therefore, option (a) is incorrect.
(c) Sunlight is necessary for photosynthesis
Sunlight is one of the important requirements for plants to carry out photosynthesis. Since photosynthesis takes place in two phases, viz. light and dark phase, in the light phase, sunlight energy is used to split a water molecule, which releases two electrons, from which NADPH and ATP molecules are formed.
Therefore, option (c) is incorrect.
(d) Carbohydrate are formed during photosynthesis
Photosynthesis, the process by which green plants and some other organisms convert light energy into chemical energy. During photosynthesis, light energy is captured in green plants and used to convert water, carbon dioxide and minerals into oxygen- and energy-rich organic substances. And the energy-rich compound or food produced is a carbohydrate.
Therefore, option (d) is incorrect.
