Nov 28, 2020 - Photosynthesis Concept Class 10 Video | EduRev is made by best teachers of Class 10. Emerson effect and Red drop: R. Emerson and C.M. During the process of photosynthesis, carbon dioxide enters through the stomata, water is absorbed by the root hairs from the soil and is carried to the leaves through the xylem vessels. Glucose is a source of food for plants that provide energy for. The complete process of the Calvin cycle takes place in the stroma of the chloroplasts. Photosynthesis is one of the toughest topics for students to grasp. So 15% of the total carbon dioxide in the atmosphere moves into photosynthetic organisms each year. Question 3: Give some adaptations in a green leaf for photosynthesis. Heterotrophs PPM stands for Parts-Per-Million. In plants, the light-dependent reaction takes place in the thylakoid membranes of chloroplasts. Photosynthesis is essential for the existence of all life on earth.
