Easy Science for Kids Photosynthesis: How Plants Make Food and Energy
Plants use about ninety percent of the food they make to grow and reproduce.

Carbon dioxide and water are inorganic chemicals, whereas glucose is an organic chemical. Plants need energy to convert carbon dioxide and water into glucose; this energy comes from sunlight. Plants can also use artificial light providing that it contains the right frequencies (). Light energy is trapped by a green chemical called chlorophyll. In photosynthesis, light energy is converted into chemical energy. When animals and plants respire, the chemical energy in glucose can be converted into other forms of e.g. kinetic energy.
Photosynthesis is the first stage of energy flow through an ecosystem. You and all other animals on earth rely on the energy that plants store for life. But animals aren’t the only organisms that burn energy. Plants burn energy as they grow, too. In both plants and animals, the process of — which releases stored energy for use — occurs in the mitochondria inside each cell.

A note on the chemical change formulas for photosynthesis and cellular respiration. Activities 4.1 and 4.3 simplify the full story of what happens to matter during the multi-step processes of cellular respiration and photosynthesis. For a more detailed account, see ..
This incorrectly suggests that some of the oxygen atoms in CO2 end up in O2, which does not happen directly during the multi-step process of photosynthesis. A more accurate formula to represent the multi-step process would be as follows:
How Do Plants Make Food? How Photosynthesis Works?
Activity 4.4, is the second part of the Explanations Phase of the instructional model (going down the triangle) for photosynthesis. Students use the Explanations Tool to construct final explanations of how plants make their own food. Ideally, at this phase their explanations will combine evidence from the macroscopic-scale observations during the investigation with their new knowledge of chemical change at the atomic-molecular scale. The questions in this Activity should also help students notice two important relationships:
Activity 4.3, is the first part of the Explanations Phase of the instructional model (going down the triangle) for photosynthesis. Students construct molecular models of the chemical change that explains how the plants give off oxygen in the light.

This lesson helps middle school and high school students understand why plants “breathe” (i.e., exchange gases with the air) differently in the light and in the dark and how the mass of plants can come mostly from the air. As they model photosynthesis, they learn how to explain plant gas exchange and growth in a way that follows the key rules about matter and energy—atoms last forever and energy lasts forever (in chemical changes). As they model cellular respiration, they learn how to explain this carbon-transforming process that makes food energy available to plant cells.
Photosynthesis: How Plants Make Food and Energy?
Plants absorb water through their roots, and carbon dioxide through their leaves. Some glucose is used for respiration, while some is converted into insoluble for storage. The stored starch can later be turned back into glucose and used in respiration. Oxygen is released as a by-product of photosynthesis.
and photosynthesis is the process that plants use to get ..
Printout A plant is a member of the kingdom Plantae, a living organism that utilizes photosynthesis, a process in which energy from sunlight is converted to chemical energy (food).

Students use molecular models to learn how matter and energy are transformed in plants during photosynthesis and cellular respiration. The focus of this lesson is on developing explanations for how plants make food, move, and function in the light and in the dark.
Biology of Plants: Introduction - MBGnet
Plants are called . This is because they They do this by using light energy from the Sun, carbon dioxide from the air and water from the soil to produce food - in the form of glucouse/sugar.
The process is called . Click on the image below to learn about photosynthesis.

A note on cellular respiration. Students usually do not think about plants doing cellular respiration. They learn that plants do photosynthesis, and often cellular respiration is overlooked. Students may not even wonder how seeds actually sprout when they have no leaves, no chlorophyll, and no way to photosynthesize. Fully grown plants also undergo cellular respiration on a continuous basis. It is easier to detect this process in plants during the night, as well as in winter months, when plants are not also photosynthesizing. During cellular respiration, plants take organic materials and oxidize them, which releases energy and gives off inorganic carbon dioxide and water as wastes. Many students also incorrectly see cellular respiration as the way plants convert food or stored biomass (fat, starch) into energy for movement, cell functions, and growth. Students need to develop an explanation of cellular respiration that conserved both matter and energy, and makes the connection between atomic-molecular transformations and macroscopic observations.
