Some facts about Photosynthesis


Photosynthesis Animals need other animals or plants in order to receive food energy. Photosynthesis is affected by temperature, light intensity, light wavelength and carbon dioxide level. Almost all plants needs the sun in order to survive. The energy for photosynthesis comes from light.


Photosynthesis process Photosynthesis is the single most important chemical process on the earth Plants are also crucial to human life because we rely on them as a source of food for ourselves and for the animals that we eat Animals need other animals or plants in order to receive food energy Photosynthesis is affected by temperature, light intensity, light wavelength and carbon dioxide level


Photosynthesis process Photosynthesis provides us with most of the oxygen we need in order to breathe We, in turn, exhale the carbon dioxide needed by plants Pine trees and other conifers have evolved over the years to grow in a triangle shape because of photosynthesis The triangular shape exposes most of its needles to the sun, especially the ones near the top of the tree


Interesting facts about Photosynthesis process Photosynthesis takes place in the chloroplasts of plant leaf mesophyll cells Light energy is converted to chemical energy by chlorophyll Photosynthesis is affected by temperature, light intensity, light wavelength and carbon dioxide level Photosynthesis consists of two series of biochemical reactions, called the light reactions and the dark reactions


Interesting facts about Photosynthesis process The light reactions use the light energy absorbed by chlorophyll to synthesize structurally unstable high-energy molecules The dark reactions use these high-energy molecules to manufacture carbohydrates All living things depend on the organic molecules synthesised by plants as a result of photosynthesis


Interesting facts about Photosynthesis process Plants need large amounts of nitrogen, phosphorus and potassium Nitrogen helps them grow and make leaves Phosphorus helps grow strong roots Potassium helps the plant reproduce and it keeps them healthy
