The correct Answer is:
To solve the question regarding the effects of ozone present in the troposphere, we can break down the information step by step. ### Step-by-Step Solution: 1. **Understanding Ozone Layers**: - Ozone exists in two main layers of the atmosphere: the stratosphere and the troposphere. - In the stratosphere, ozone is beneficial and protects us from harmful UV radiation. This is often referred to as "good ozone." - In contrast, ozone in the troposphere is considered "bad ozone" and is a significant air pollutant. **Hint**: Remember the difference between good ozone (stratosphere) and bad ozone (troposphere). 2. **Effects of Tropospheric Ozone**: - The ozone in the troposphere is highly reactive and can cause various harmful effects. - It is known to promote the oxidation of biochemicals due to its reactivity. This means it can react with and damage various organic compounds. **Hint**: Focus on the reactivity of tropospheric ozone and its role in biochemical oxidation. 3. **Impact on Plant Life**: - Tropospheric ozone can also damage plant tissues, particularly chlorenchyma, which is the tissue in plants that contains chloroplasts and is essential for photosynthesis. - By damaging chlorenchyma, ozone negatively affects the growth and health of plants. **Hint**: Consider how ozone affects plant tissues and their ability to perform photosynthesis. 4. **Evaluating the Options**: - The options provided are: A) Oxidation of biochemicals B) Destruction of chlorenchyma C) Both A and B D) Growth of plants - Since we established that ozone promotes both the oxidation of biochemicals and the destruction of chlorenchyma, the correct answer is option C) Both A and B. **Hint**: Look for options that encompass multiple effects of ozone rather than just one. ### Final Answer: The ozone present in the troposphere promotes both the oxidation of biochemicals and the destruction of chlorenchyma, making the correct answer: **C) Both A and B**.

Assertion: Excess of ozone in troposphere called bad ozone while excess in stratosphere is known as "good" ozone. Reason: In troposphere ozone acts as pollutant while in stratosphere it protects from U.V. radiations.

Read the following statements and select the correct option. Statement 1 : Ozone layer present in the stratospher protects the living organisms from harmful UV rays coming from sun by absorbing nearly all of them. Statement 2 : Ozone formed in the troposphere by photochemical reactions as a result of human activities is harmful for all living organisms.
