Question 10

Mark ‘T’ if the statement is true and ‘F’ if it is false:
(i) Carbon dioxide is released during photosynthesis. (T/F)
(ii) Plants which synthesise their food themselves are called saprotrophs. (T/F)
(iii) The product of photosynthesis is not a protein. (T/F)
(iv) Solar energy is converted into chemical energy during photosynthesis. (T/F)

Answer

(i) False                                                                                                                                                                                                                                          During photosynthesis oxygen is released and intake of carbon dioxide occurs.

(ii) False                                                                                                                                                                                                                                              The living organism which take their nutrition from dead or decaying matter is called Saprotrophs.

(iii) True                                                                                                                                                                                                                                    Sunlight, water and carbon dioxide are three main components that are necessary for photosynthesis process, which gives end result as oxygen and glucose. The final result of photosynthesis is, therefore is glucose and oxygen, not a protein.

(iv) True                                                                                                                                                                                                                                            In photosynthesis, solar energy is used and converted to chemical energy in the form of glucose by using water and carbon dioxide. Oxygen is released as a end product.
