A. from a floating plant B. from submerged plant C. varigated D. from a terrestrial plant E. from parasitic green plant
Correct Answer: B
Explanation
The correct answer is:
B. from submerged plant
Explanation: Submerged aquatic plants live entirely underwater and usually lack stomata, because gas exchange occurs directly through the surface of the leaf from the surrounding water. Stomata are unnecessary in this environment.
- Floating plants (like water lilies) usually have stomata on the upper surface of their leaves. - Terrestrial and parasitic green plants generally have stomata to facilitate gas exchange.
