The presence of carbon dioxide, water, chlorophyll and sunlight is necessary for the process of photosynthesis to take place. We can extract oil from sunflower seeds and use it as a food. Certain plants convert the simple carbohydrate glucose made during photosynthesis into oils and store them in their seeds. Preview this quiz on Quizizz. Question 17 Name foods made by plants which are important part of our diet? (1) How the plants obtain Carbon Dioxide for photosynthesis – The plants take carbon dioxide gas from air through the tiny pores (called stomata) present on the surface of leaves.Each pore is surrounded by a pair of guard cells. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and â¦ But remember, you still have to water them! Nitrates are the water soluble nitrogen compounds which are absorbed by the plants from the soil along with water. Those organisms which can not make food themselves by the process of photosynthesis and take food from green plants or animals, are called heterotrophs (and their mode of nutrition is called heterotrophic). (2) The process of photosynthesis by plants puts oxygen gas into the air: It is this oxygen gas which the animals (including human beings) use for breathing and respiration. After this lesson, students will be able to: 1. chloroplast. Question 3 Name the pores through which leaves exchange gases? The final products of photosynthesis are oxygen and glucose.
