During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.

What are the 3 process of photosynthesis?

The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.

What is the process of photosynthesis in your own words?

The definition of photosynthesis is the process through which plants use water and carbon dioxide to create their food, grow and release excess oxygen into the air. Photosynthesis uses sunlight, carbon dioxide and water to produce oxygen, glucose and water.

What are the 7 steps of photosynthesis?

What are the 7 steps of photosynthesis?

• 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. ...
• Step 4-Light Dependent.
• Step 5-Light independent.
• Step 6-Light independent.
• calvin cycle.

What is photosynthesis in long answer?

Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules.

How many steps are there in photosynthesis?

Photosynthesis takes place in two sequential stages: The light-dependent reactions; The light-independent reactions, or Calvin Cycle.

Why is photosynthesis a 2 step process?

Photosynthesis represents the biological process by which plants convert light energy into sugar to fuel plant cells. Comprised of two stages, one stage converts the light energy into sugar, and then cellular respiration converts the sugar to Adenosine triphosphate, known as ATP, the fuel for all cellular life.

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. ... In this form the plants can use the glucose,and water for food and release the oxygen back into the air for consumption by animals, including humans.

How do plants breathe?

Do Plants 'Breathe'? ... Plants do require oxygen for respiration which in return give out carbon dioxide. Unlike animals, plants do not have any specialized structures for gaseous exchange but they have stomata (present in leaves) and lenticels (present in stems) which are involved in the exchange of gases.

How does a flower eat?

Flowers get their food from sunlight. Flowers are the reproductive parts of plants, and plants are unique among living things in that they make their own food in special cells called chloroplasts.

How do plants eat?

Plants don't eat food. They use the energy from the sun, or other light and use it to make their food. The ingredients for this process are water, air, and light. Plants don't use all the parts of the air, they only use the carbon dioxide (CO2) to make their food.

Do plants excrete?

Unlike animals, plants do not have specialised excretory organs. Excess carbon dioxide and oxygen are excreted from the plant through the stomata in the leaves.

What is the first stage of photosynthesis?

Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.

Which is the final step in photosynthesis process?

The last stage of the photosynthesis process is known as the Calvin-Benson cycle, in which the plant uses atmospheric carbon dioxide and water from soil to convert ATP and NADPH. The chemical reactions that make up the Calvin-Benson cycle occur in the stroma of the chloroplast.

What is ADP and NADP?

ATP - Adenosine triphosphate. ADP - Adenosine diphosphate. NADP - Nicotinamide adenine dinucleotide phosphate. NADPH - The reduced form of NADP. In the Light Dependent Processes i.e Light Reactions, the light strikes chlorophyll a in such a way as to excite electrons to a higher energy state.

What is photosynthesis for kids?

Photosynthesis is the process in which green plants use sunlight to make their own food. ... Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.

What is photosynthesis by Brainly in?

the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

What is photosynthesis summary?

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.
