Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What three things do plants need for the process of photosynthesis?
A
Sunlight, oxygen, and sugar
B
Water, soil, and oxygen
C
Sunlight, carbon dioxide, and water
D
Carbon dioxide, oxygen, and soil
Explanation: 

Detailed explanation-1: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-2: -Aquatic plants and land plants (flowering plants, mosses, and ferns) help to regulate atmospheric carbon by removing carbon dioxide from the air. Plants are also important for the production of oxygen, which is released into the air as a valuable by-product of photosynthesis.

Detailed explanation-3: -Carbon dioxide, water, and light are the ingredients plants need in order to make their food to grow. Carbon dioxide is a gas that we humans breathe out.

Detailed explanation-4: -During photosynthesis, carbon dioxide, a gas, is combined with water and solar energy, and converted to carbohydrates, a solid. Formation of carbohydrates is a chemical way to store the sun’s energy as “food.” Carbohydrates produced from photosynthesis provide energy for all plant growth and maintenance.

Detailed explanation-5: -Used for respiration (both aerobic and anaerobic) Converted into insoluble starch for storage in the stems, leaves and roots. Used to produce fat or oil for storage (especially in seeds) Used to produce cellulose, which strengthens the cell wall. More items
