It can be visualised that both C 4 cycle and photorespiration are the result of evolution or might have been one of the reasons of evolution for the adaptation of plants to different environments. Two cell organelles. Leaves contain microscopic cellular organelles known as chloroplasts. In other words, these sugars are used by the plants as an energy source, which helps them to grow. The process of photosynthesis takes place in the dark. Gather evidence of inputs and outputs of photosynthesis Grade level: Grade 7, 8. Another by-product of photosynthesis is sugars such as glucose and fructose. I couldn’t find the answer anywhere. Illustrate the relationship between light and photosynthesis (i.e., you need light source for plants to grow; more light more photosynthesis) 3. Light-independent reaction is also called the dark reaction or the Calvin cycle. It corresponds to saying that 300 PPM of carbon dioxide indicates that if one million gas molecules are counted, 300 out of them would be carbon dioxide. Photosynthesis is so essential to life on earth that most living organisms, including humans, cannot survive without it.

Photosynthesis also applies to other organisms besides green plants. 4. The bacteria that do produce oxygen as a by-product of photosynthesis are called oxygenic photosynthetic bacteria. Also, I hope that you have written the questions and … Structure of Chloroplast. Interactive The sugar made by this process is the main source of food for many animals. Explain the process of photosynthesis 2. Break the class into groups of 3 or 4 students each (depending on the size of the class) and give each of group two of the same potted plant. This chemical energy is stored in the form of sugar (C 6 H 12 O 6) that can later be used to fuel the organism's activities. Oxygen is released from the leaves into the atmosphere. Chlorophyll absorbs the light energy from the sun to split water molecules into hydrogen and oxygen. Photosynthesis is one of the most crucial life processes on the Earth. These organisms exhibit photosynthesis just like green plants. 4. Flowers serve a reproductive purpose, so again, there's no reason for plants to use them for photosynthesis. Meaning of Photosynthesis ,lesson for kids They are the molecules that impart colour and they absorb light at some specific wavelength and reflect back the unabsorbed light.
