Question

Which of the following statements accurately describes the relationship between photosynthesis and cellular respiration? Photosynthesis occurs only in autotrophs; cellular respiration occur only in heterotrophs Photosynthesis uses solar energy to convert inorganics to energy-rich organics respiration breaks down energy-rich organics to synthesize ATP Photosynthesis involves the oxidation of glucose; respiration involves the reduction of CO_2 The primary function of photosynthesis is to use solar energy to synthesise ATP, the primary function of cellular respiration is to break down ATP and release energy What organelle is responsible for photosynthesis in plants and algae? Mitochondria Chloroplast Chlorophyll Cellular Membrane Which of the following is summary of photosynthetic pathway? Glucose + Oxygen = Carbon dioxide + Water + ATP Carbon dioxide + Water = Glucose + Oxygen + Water Carbon dioxide + Water = Lactic acid + Electron Glucose + ATP = Carbon dioxide + Oxygen Which of the following statement is not true for Photosynthesis? It occurs in two phases; light reactions & dark reactions Only light reactions utilizes radiant energy Light energy is converted my mechanical energy Electrons ae transferred to & thus reduce NADP^+ Photosynthesis takes place in the membranes of small sacs called Thylakoids Grana

Explanation / Answer

Answer 10) The correct answer is option (B).
Photosynthesis is the process of conversion of inorganic raw materials (water, carbon dioxide and sunlight) into energy-rich organic compounds. Respiration is a process which uses energy-rich organics (glucose) to synthesise ATP and formed carbon dioxide and water.

Answer 11) The correct answer is option (B).
The chloroplast is an organelle present in the leaves of the plant and is involved in the photosynthesis process. It contains a green pigment chlorophyll which captures sunlight which is an important raw material for the food synthesis.

Answer 12) The correct answer is option (B).
The overall reaction of photosynthesis is as follows:
6CO2   + 6H2O C6H12O6 + 6O2
Carbon dioxide water Glucose oxygen

Answer 13) The correct answer is option (C).
Photosynthesis converts light energy into chemical energy in the form of ATP and NADPH.

Answer 14) The correct answer is option (A).
The photosynthesis takes place in the membranes of small sacs called thylakoids. Thylakoids of the chloroplast form stacks of disks known as grana which provide the optimum surface area for enhancing the rate of photosynthesis.
