Question

In addition to light and chlorophyll photosynthesis requires

Answer 1

presence of carbon dioxide, nutrients, minerals & water.

Step-by-step explanation:

Photosynthesis is the process of generation of energy by the green plants at the cellular level. This process occurs in the presence of sunlight, a green pigment called chlorophyll, water, carbon dioxide, minerals and nutrients which plants absorb from the soil via its roots.

Oxygen is released as the by-product of this process. It also produces carbohydrates, simple sugars are used by the plants for their survival.

The formation of glucose during the process is chemically represented as:

• 
  `6CO_2+6H_2O\rightarrowC_6H_12O_6+6O_2`

Answer 2

Water (H₂O) and Carbon dioxide (CO₂)

Step-by-step explanation:

Photosynthesis usually refers to the process by which the green plants can synthesize their own food in the presence of sunlight, water, carbon dioxide, and light. This process helps in the conversion of light energy into chemical energy.

In addition to the sunlight and chlorophyll, the process of photosynthesis requires water as well as carbon dioxide. The plants are comprised of green pigments on their leaves that are commonly known as chlorophyll. These pigments absorb the water molecules and carbon dioxide gas that helps in synthesizing their food.

The equation for the process of photosynthesis is given below:

6CO₂ + 6H₂0 + (energy) → C₆H₁₂O₆ + 6O₂
