Direction: The following question consists of two statements - Assert...
A is true but R is false. In woody plants, gaseous exchange occurs through the small pores found on stems called lenticels. Stomata on the stem aid in gaseous exchange, in herbaceous plants. Assertion is true, but Reason is false.

Direction: The following question consists of two statements - Assert...
Assertion and Reasoning: Woody plants and gaseous exchange
Assertion: In woody plants, gaseous exchange occurs through lenticels.
Reason: Lenticels are specialised cells found along with stomata on the stem of woody plants.
Explanation:
• The Assertion states that gaseous exchange takes place through lenticels in woody plants. Lenticels are small pores or openings on the bark of woody stems and roots, which allow for gas exchange to occur.
• The Reasoning explains that lenticels are specialised cells found along with stomata on the stem of woody plants. Stomata are small openings on the leaves of plants that allow for gas exchange. However, in woody plants, lenticels are present on the stem instead of leaves, and they carry out the function of gas exchange along with stomata.
• Therefore, the Assertion is true as lenticels are responsible for gaseous exchange in woody plants. However, the Reasoning is false as lenticels are not specialised cells but rather small pores or openings on the bark of woody stems and roots.
• Hence, the correct option is (c) A is true but R is false.
Conclusion:
Gaseous exchange in woody plants occurs through lenticels, which are small pores or openings on the bark of woody stems and roots. Lenticels are not specialised cells but rather small openings that allow for gas exchange to occur along with stomata.
Direction: The following question consists of two statements - Assert...
Lenticels are found on stems of wooden plants, not stomata. Stomata are found solely on leaves.
