Does petroleum jelly affect transpiration?

Covering the lower side of the leaves with petroleum jelly would block the stomata and prevent the evaporation of water from the leaf.

How would petroleum jelly affect transpiration?

The petroleum jelly blocks the stomata, so that water cannot escape from the leaf. … As a result, less water is lost from these stomata than from those on the upper surface of leaves. This helps prevent excess water loss from the plant.

How does vaseline stop transpiration?

Covering the lower side of the leaves with petroleum jelly (Vaseline) would block the stomata and prevent the evaporation of water from the leaf (Transpiration) and we know that transpiration is very important for the ascent of sap in plants. Hence, vaseline prevents ascent of sap.

What effect would oil or vaseline have on transpiration in plants?

Complete answer:

Vaseline layer hinders from receiving sunlight and affects the process of photosynthesis. No transpiration will take place and the plant will die. Stomata are the openings or pores present on the lower side of the leaves. It helps in the gaseous exchange.

Will petroleum jelly hurt plants?

Dabbling in Oil

Never smear vaseline on the stalks unless its late flower, use double sided tape instead, It’s stretchy and won’t harm your plant.

IMPORTANT TO KNOW:  Why do we need to compress natural gas during transportation?

At what time of the day do plants respire?

Question 9. Q9) DO plants respire all day and night or only during the night? Solution: Plants respire during the night, plants release carbon dioxide and take in oxygen and oxidation of stored food by absorbed oxygen takes place.

What factors affect transpiration?

The rate of transpiration is affected by several factors, including:

  • temperature.
  • humidity.
  • wind speed.
  • light intensity.

What happens if stomata are blocked?

If stomata are choked due to dust, gaseous diffusion through stomata will get hampered. Plants will not get sufficient carbon dioxide, nor oxygen produced during photosynthesis can escape out.

What will happen if epidermis is covered with Vaseline?

Explanation: (A)Applying Vaseline, in real life experiment it will reduce water loss from upper surface to moderate and from lower surface to minimum ( more stomata is present on lower surface). … The stomata would be covered and there would be no photosynthesis and transpiration.
