Answer 1

Question

41. The cellular respiration is the process of breakdown of glucose in to carbon-dioxide and water. The carbon -dioxide is breathed out during respiration. Hence, option C is correct.

42. Plants are phototrophic organisms, it means they take carbon dioxide and fix into that carbon dioxide into glucose with the help of sun-light. Hence, option B is correct.

43. According to endosymbiotic theory, eukaryotic organelle arise from the prokaryotic cell. Hence, option C is correct.

44. When the sunlight hits the chlorophyll it releases electrons and that go to PSI, PSII and eventually end up in electron. Hence, option B is correct.
