Question

What will happen if epidermis of the leaf is covered by a layer of oil?

Answer 1

Answer:

If you cover the leaves of healthy plant with oil, it will block its stomata and therefore it will not remain healthy for a long time. This is because the

• plant will not get oxygen for respiration, It will not get carbon dioxide for photosynthesis.

• It helps in maintaining the leaf surface temperature by causing cooling effect through evaporation and also creates a transpirational pull i.e it causes roots to absorb water and this helps in absorbing nutrient and also flow of water through xylem( helps in circulation of nutrients for various metabolic process) upto stomata in leaves.
• Plant uptakes CO2 in daytime to produce it own food . By closing stomata it will not perform Photosynthesis anymore and hence will die out of starvation.
• Plant uptakes Oxygen in night-time for Respiration i.e breakdown of its food reserves for energy. This process will also stop causing the plant to die.
• contains the residue and compounds of petrol and its product which is very harmful for the plants and these composition can dry up a plant if applied on their leaves.
• If you cover the leaves of healthy plant with vaseline, it will block its stomata and therefore it will not remain healthy for a long time. This is because plant will not get oxygen for respiration. it will not get carbon dioxide for photosynthesis.
• The plant will not lose water through transpiration so the upward movement of the water in the plant will stop.
