What is photosynthesis Class 3 Short answer? 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.
What are the two stages of photosynthesis?
Photosynthesis occurs in two stages commonly known as Light dependent Reactions and the Calvin Cycle. Light dependent reactions occur in the thylakoid membrane of the chloroplasts and take place only when light is available.
What is photosynthesis in biology?
What is photosynthesis? Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive. Carbon dioxide, water and light are all needed for photosynthesis to take place. Photosynthesis happens in the leaves of a plant.
What is needed for photosynthesis to take place?
and light energy. During photosynthesis, the chlorophyll in leaves help convert carbon dioxide and water into the products oxygen and glucose. The glucose acts as a vital source of food for the plant. Carbon dioxide, water and light are all needed for photosynthesis to take place.
What are the two types of photosystems?
There are two types of photosystems: photosystem I and photosystem II. Under the light-dependent reactions, the light energy is converted to ATP and NADPH, which are used in the second phase of photosynthesis.
What is photosynthesis short answer?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What is photosynthesis class4?
Photosynthesis is defined as the process by which plants prepare their food from sunlight, chlorophyll, carbon dioxide, and water. The chlorophyll plays a key role in photosynthesis as it helps to prepare food for the plants. The chlorophyll is present in the leaves of the plants.

What CBSE photosynthesis?
Photosynthesis. Photosynthesis. The process by which plants make their own food in the presence of sunlight, carbon-dioxide present in air, water, minerals and chlorophyll present in leaves is termed as photosynthesis.
What is photosynthesis class6?
Hint: Photosynthesis is the process by which green plants prepare their own food with the help of carbon-dioxide, water, chlorophyll and light. By this process the light energy is converted into chemical energy.Photosynthesis nourishment in light was discovered class 6 biology CBSEhttps://www.vedantu.com › question-answerhttps://www.vedantu.com › question-answerSearch for: What is photosynthesis class6?
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.Sep 28, 2010Photosynthesis Lesson Plans for 5th Grade - BrightHub Educationhttps://www.brighthubeducation.com › lesson-plans-grade...https://www.brighthubeducation.com › lesson-plans-grade...Search for: What is photosynthesis 5th grade?

What is the energy that is transferred to the photosynthesis process?
Chlorophyll and other pigments absorb energy from sunlight. This energy is transferred to the photosystems responsible for photosynthesis. Water is used to provide electrons and hydrogen ions but also produces oxygen.
Where does photosynthesis take place?
The photosynthesis process takes place in the leaves of plants. The leaves are made up of very small cells. Inside these cells are tiny structures called chloroplasts. Each chloroplast contains a green chemical called chlorophyll which gives leaves their green color. Chlorophyll absorbs the sun’s energy.
How are carbon dioxide and water absorbed by plants?
Let’s take a look at how these are collected by plants. Carbon dioxide from the air passes through small pores (holes) in the leaves. These pores are called stomata. Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves. Sunlight is absorbed by a green chemical in the leaves.
What is the energy that is released from the leaves of plants?
Chlorophyll absorbs the sun’s energy. It is this energy that is used to split water molecules into hydrogen and oxygen . Oxygen is released from the leaves into the atmosphere. Hydrogen and carbon dioxide are used to form glucose or food for plants.
What are the electrons and hydrogen ions used to make ATP and NaDPH?
The electrons and hydrogen ions are used to create ATP and NADPH. ATP is an energy storage molecule. NADPH is an electron carrier/donor molecule. Both ATP and NADPH will be used in the next stage of photosynthesis.
Why is photosynthesis important?
Photosynthesis is important because it provides two main things: food. oxygen. Some of the glucose that plants produce during photosynthesis is stored in fruits and roots. This is why we are able to eat carrots, potatoes, apples, water melons and all the others. These foods provide energy for humans and animals.
What is the role of oxygen in photosynthesis?
Oxygen that is produced during photosynthesis is released into the atmosphere. This oxygen is what we breathe and we cannot live without it. While it is important that photosynthesis provides food and oxygen, its impact on our daily lives is far more extensive.
What do plants need to do photosynthesis?
For photosynthesis to take place, plants need to take in carbon dioxide (from the air), water (from the ground) and light (usually from the sun).
Where does photosynthesis take place?
Carbon dioxide, water and light are all needed for photosynthesis to take place. Photosynthesis happens in the leaves of a plant.
