Answer:
The correct answer is option 'A', which states that the droplets of water arranged at the edges of leaves of roses in the morning are water transpired from the stomata and lenticels. Let's discuss this in detail.
Water Transpiration from Stomata:
- Stomata are tiny openings present on the surface of leaves and stems of plants. They help in the exchange of gases and water vapor between the plant and the atmosphere.
- During the process of transpiration, water is lost from the plant through the stomata in the form of water vapor. This process helps in cooling the plant and maintaining its temperature.
- In the morning, when the temperature is relatively lower and the air is cooler, the water vapor present inside the plant condenses on the surface of the leaves, forming droplets of water.
- These water droplets then accumulate and arrange themselves along the edges of the leaves, creating a beautiful sight commonly observed on roses and other plants.
Water Transpiration from Lenticels:
- Lenticels are small openings or pores present in the bark of woody stems and branches of plants.
- Similar to stomata, lenticels also aid in the exchange of gases and water vapor.
- Water transpiration can also occur through these lenticels, especially in plants with thicker or woody stems.
- When water transpires through lenticels, it can also condense on the surface of the leaves in the form of droplets.
Other Options:
- Option 'B' suggests that the water droplets are condensed from the atmosphere during the night at low temperatures. While condensation does occur during the night, it is mainly due to the temperature difference between the air and the cool leaf surfaces. However, the primary source of the water droplets arranged on the leaves is transpiration.
- Option 'C' states that the water is produced on the leaves from the reaction of hydrogen and atmospheric oxygen. This is incorrect, as water is not produced on the leaves through a chemical reaction. Water is absorbed by the roots and transported to the leaves through the xylem vessels.
Therefore, the correct answer is option 'A' - the droplets of water arranged at the edges of leaves of roses in the morning are water transpired from the stomata and lenticels.

Due to the absence of the sun water can not evaporate after transpiration so it gets arranged in the edges of the leaf
