Concept explainers
Which of the following is True?
a. Photosynthesis evolved in an atmosphere with little or no oxygen.
b. Photosynthesis occurs only in plants.
c. Oxygen is necessary for photosynthesis.
d. Carbon dioxide is necessary for photorespiration.
Introduction:
Animals use respiration process wherein the exchange of gases and breathing process is attained. The upper and lower respiratory system works in conjunction and achieves the desired function of the respiratory system. Just like animals, plants also use a process of respiring and this is done by the photosynthesis process.
Answer to Problem 1MC
Correct answer:
Photosynthesis is evolved in the atmosphere with almost null of limited oxygen content.
Explanation of Solution
Explanation for the correct answer:
Option (a) is given as photosynthesis has evolved in the atmosphere with no to little oxygen content. During photosynthesis, the plants and other organisms utilize sunlight, water, and carbon dioxide in order to generate oxygen in the atmosphere. The oxygen liberated by the plants into the atmosphere is taken up by the animals and other organisms which depend on the oxygen. Therefore, option (a) is a correct answer.
Explanation for the incorrect answer:
Option (b) is given as photosynthesis occurs only in plants. The photosynthesis occurs in plants and other organisms, which convert the light energy coming from the sun into chemical energy. So, it is an incorrect option.
Option (c) is given as oxygen is necessary for photosynthesis. Carbon dioxide, sunlight, and water are necessary components for photosynthesis process and the final product is the release of oxygen. So, it is an incorrect option.
Option (d) is given as carbon dioxide is necessary for photorespiration. It is seen in higher plants which take up oxygen during the daytime and generate carbon dioxide at night. So, it is an incorrect answer.
Hence, options (b), (c), and (d) are incorrect.
Therefore, it can be concluded that the photosynthesis produces oxygen for other animals and uses up sunlight, water, and carbon dioxide.

You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different.
