How is the process of photosynthesis?
How is the process of photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
What is photosynthesis in kid friendly?
Photosynthesis is the process in which green plants use sunlight to make their own food. Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars. The plants use some of the sugars and store the rest. The oxygen is released into the air.
What 4 things do plants need to carry out photosynthesis?
Glucose is why plants need photosynthesis. To review, the ingredients for photosynthesis are water, carbon dioxide and light energy.
What are the two cycles of photosynthesis?
Within the chloroplasts of a plant cell, photosynthesis occurs in two main phases: the light-dependent and light-independent reactions.
How do plants use photosynthesis?
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
What is photosynthesis for 3rd class?
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.
What are facts about photosynthesis?
– The energy for photosynthesis comes from light. Light energy is converted to chemical energy by chlorophyll. There are two sets of reactions, light dependent and light independent. The process mostly takes place in the chloroplasts of plant leaf mesophyll cells.[1] – Photosynthesis is the process where a plants uses the sun’s energy to turn light into chlorophyll. Plants produce oxygen during this process and utilize carbon dioxide. Photosynthesis is the single most important chemical process on the earth. Almost all plants needs the sun in order to survive.[2] – · Photosynthesis is the most important chemical process on earth – it provides food and energy for all living creatures who eat the plants that rely on this process to produce their food (glucose). · More than half (70%) of the world’s oxygen is produced by phytoplankton photosynthesis in the world’s oceans.[3]
What are the three stages in photosynthesis?
Photosynthesis has two main stages: light reactions and the Calvin cycle; the Calvin cycle has three stages called carbon fixation, reduction and regeneration of RuBP.
What is the role of cellular respiration in photosynthesis?
The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
What is the electron flow in photosynthesis?
Photosynthesis uses the energy obtained from light to free electrons from the chlorophyll pigments that collect the light. Chlorophyll molecules do not have an infinite supply of electrons, so they regain the lost electron from a molecule of water.
