what are the conditions needed for photosynthesis
Answers
For photosynthesis, presence of carbon dioxide, water, chlorophyll and sunlight is required. Only when these elements are present, can photosynthesis occur in plant.
Carbon Dioxide
It is crucial for photosynthesis to occur. The outer layer of plant tissue, the epidermis, has tiny openings called stomata that take in carbon dioxide
Water
Plants use water to help break down carbon dioxide so its components can be combined with those in water to form sugar molecules. Plants absorb water through the root system.
Sunlight
An energy source is needed to convert carbon dioxide and water into sugar. Sunlight provides that energy source.
Chlorophyll
Plants take in the sun's energy with the help of chlorophyll or carotenoids. Chlorophyll are the green colored pigments which gives plants their familiar green hues and absorb energy. The presence of these pigments in leaves is important because leaves are the manufacturing sites where photosynthesis takes place.
Answer:
For photosynthesis to take place , plants need to take in carbon dioxide ( from the air) water( from the ground) and sunlight usually (from the sun) .
