The process of photosynthesis allows plants to convert energy from the sun into carbohydrates for growth. It also requires water and carbon dioxide. They get the water through their roots in the ground and carbon dioxide from the air, so they don’t need to eat anything.

How do you teach photosynthesis in a fun way?
Using construction paper and crayons or markers, have your child design a pictorial representation of photosynthesis.
- Instruct your child to draw a plant or flower on the paper.
- Have your child draw a sun above the plant to symbolize the sun’s energy.
- Ask your child to add a source of water for the plant.
What is photosynthesis for 4th graders?
Photosynthesisis a process by which plants make their own food in their leaves and give off oxygen and water that they are not using. The food made by the plant is a form of sugar called Page 8 glucose. Oxygen is a gas that is needed by many animals in order to survive.
How do you explain photosynthesis to kids?
Photosynthesis | Educational Video for Kids
What are the 4 main steps of photosynthesis?
The overall process of photosynthesis can be objectively divided into four steps/ process:
- Absorption of light. The first step in photosynthesis is the absorption of light by chlorophylls that are attached to the proteins in the thylakoids of chloroplasts.
- Electron Transfer.
- Generation of ATP.
- Carbon Fixation.
What are the 3 steps of photosynthesis?
- The following events occur during photosynthesis:
- Absorption of light energy by chlorophyll.
- Conversion of light energy to chemical energy and splitting of water molecule into hydrogen and oxygen.
- Reduction of carbon dioxide to carbohydrates.
What are the 12 steps of photosynthesis?
Terms in this set (12)
- Sunlight excites e- on chlorophyll in PSII.
- Energy transferred to P680.
- P680 donates e- to primary acceptor.
- H₂O splits to replenish e-, O₂ released.
- e- passed down electron transport chain.
- Energy from ETC used to pump H⁺ (protons) into thylakoid lumen.
What are 10 facts about photosynthesis?
10 Facts on Photosynthesis
- The green color of leaves is due to chlorophyll.
- The two main parts of a chloroplast are the grana and stroma.
- The first stage of photosynthesis captures energy from the sun to break down water molecules.
- The second stage of photosynthesis is the Calvin cycle.
Why are leaves green?
So, plants and their leaves look green because the “special pair” of chlorophyll molecules uses the red end of the visible light spectrum to power reactions inside each cell. The unused green light is reflected from the leaf and we see that light.
Why are plants green?
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
How do you introduce photosynthesis to students?
Show students a picture of a plant or a live plant and ask them to think about what they already know about plants, particularly that they are living, and living things need food. Have the class brainstorm ideas explaining how a plant gets its food. Record their ideas on the board.
What experiments can you do with photosynthesis?
Use a measuring spoon to scoop out 1/8 teaspoon of baking soda, and fill your measuring cup with 300 milliliters of water. Mix the baking soda into the water to create your bicarbonate solution. When the baking soda dissolves in the water, it releases carbon dioxide. This will be used by the spinach for photosynthesis.

What are the 7 steps of photosynthesis?
Terms in this set (7)
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
- Step 3- Light Dependent. The electrons move down to enzymes.
- Step 4-Light Dependent.
- Step 5-Light independent.
- Step 6-Light independent.
- calvin cycle.
What is photosynthesis 3rd grade?
Photosynthesis means to put together with light. Photosynthesis is a process in which green plants use energy from the sun to transform water, carbon dioxide, and minerals into oxygen. Photosynthesis gives us most of the oxygen we need in order to breathe. We, in turn, exhale carbon dioxide that is needed by plants.
What is photosynthesis 5th grade?
Photosynthesis is the big name for the process by which plants convert energy from sunlight into energy for food. This process also requires water and carbon dioxide. Plants are able to absorb rain water through their roots and receive carbon dioxide from the air through their leaves.
What 4 things do plants need for photosynthesis?
- Carbon dioxide.
- Presence of chlorophyll.
What is photosynthesis 1st grade?
Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Without it there would be no green plants, and without green plants there would be no animals. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.
What are the 5 components needed for photosynthesis to occur in a plant?
Materials Needed for Photosynthesis
- Chlorophyll. Chlorophyll, the pigment in plants that makes them green, is essential to the photosynthetic process.
- Sunlight. The process cannot work without an energy input, and this comes from the sun.
- Carbon Dioxide.
What are the two main reactions of photosynthesis?
Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle.
How does photosynthesis start?
Photosynthesis begins when light strikes Photosystem I pigments and excites their electrons. The energy passes rapidly from molecule to molecule until it reaches a special chlorophyll molecule called P700, so named because it absorbs light in the red region of the spectrum at wavelengths of 700 nanometers.
What is the main pigment in plants?
Chlorophylls. The chlorophylls, a and b, are the pigments of photosynthesis. They are produced in chloroplasts in the photosynthetic tissues of the leaf. The chlorophyll molecules are very water repelling, partly because of the long phytol tail in the molecule.
What is photosynthesis PDF?
Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.
What are photosynthesis products?
During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).
