Photo = light
Synthesis = produce/make
• Photosynthesis results in plants giving off oxygen, which is essential for many living organisms.
• Photosynthesis removes carbon dioxide from the air and prevents it from reaching a poisonous level.
• photosynthesis provides food for almost every single organism on earth.
How do plants photosynthesise?
• plants take in carbon dioxide from the air through tiny pores on their leaves called stomata (singular stoma)
• plants take in water from the soil through their roots.
• sunlight is absorbed by the chloroplasts in the cells of the leaves of the plant.
• the green pigment chlorophyll, in the chloroplasts, allows the carbon dioxide and water to combine to form glucose.
• The energy for this reaction comes from sunlight.
• oxygen is released and given off as a waste product.
