Question

how do plants make food on a cloudy day.

Answer 1

Answer:

Basically photosynthesis needs sunlight, which is a basic requirement for producing glucose in its presence. But during cloudy days, the activity reduces to a certain extent because the plant is not exposed to sufficient sunlight. Sunlight is directly the main source for the process of Photosynthesis in plants.

Answer 2

Answer:Plants makes food with the process of photosynthesis in a cloudy day but at a decrease rate because intensity and spectrum are crucial requirements.

How plants make food in a cloudy day?

• There must be light even when the sky is cloudy.Therefore, photosynthesis can occur possibly at a decreased rate in some plants.Remember that while light is required for photosynthesis, it need not be sunlight.
• The spectrum values and the intensity of the light are crucial requirements. Any plant might live only under electric light and never see the sun. 
• The fact that some plant species can survive in lower light levels makes them good houseplant candidates.
• Other plant species are adapted to the lower levels of light found in deep shade on forest floor.
• Despite reduced photosynthesis, plant cells still store food for the plant to use if food production level decline, just as animal bodies do if consumption does.
• Despite reduced photosynthesis, plant cells still store food that they can use if food production levels decrease, much as animal bodies do if intake drops.

What is chemosynthesis?

• Instead of producing food through photosynthesis, some uncommon autotrophs engage in a mechanism known as chemosynthesis.
• Chemosynthesis is a process used by autotrophs to create food without the usage of solar energy. 
• Instead, they use the energy from chemical reactions to produce food, frequently mixing methane or hydrogen sulphide with oxygen.
• By using chemicals as their energy source rather than sunlight, bacteria produce food (glucose) through a process known as chemosynthesis. 
• Where there is no sunshine, chemosynthesis takes place at hydrothermal vents and methane seeps in the deep ocean.
•  Bacteria found on the ocean floor or inside of mammals use the energy contained in the chemical bonds of hydrogen sulphide and methane to create glucose from water and carbon dioxide during chemosynthesis (dissolved in sea water). 
• As a byproduct, pure sulphur and sulphur compounds are created.
