Conditions required for photosynthesis

Answer 1

Conditions needed for photosynthesis

Photosynthesis needs:

• chlorophyll
• carbon dioxide (from the air)
• water (from the soil)
• sunlight energy (any light will do except green light)
• Tree and offshoots. (Roots, leaves, trunk, etc.)

Photosynthesis produces:

• glucose
• oxygen (a waste product)
• water vapor (US spelling) (through a process called transpiration)

Chlorophyll and light energy both need to be present for photosynthesis to take place, but they are not actually part of the reaction - they are not used up. So in the word equation for photosynthesis, remember to write them above the arrow, like this:

Answer 2

Photosynthesis requires light, water, carbon dioxide, and chlorophyll. Light energy is absorbed by chlorophyll to convert carbon dioxide and water into glucose and oxygen through a series of chemical reactions. This process occurs in the chloroplasts of plant cells.

Answer 3

Photosynthesis requires sunlight, water, and carbon dioxide. Water and sunlight are used during the light reaction, and carbon dioxide is used in the Calvin Benson Cycle (Dark reaction).
