What is photosynthesis in biology simple definition?

photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Where does oxygen come from in photosynthesis?

Oxygen liberated during photosynthesis comes from the splitting or hydrolysis of water in the green plants. Cornelius van Niel experimentally proved for the first time that the oxygen liberated during photosynthesis comes from water and not from carbon dioxide.

What is oxygen in plants?

Oxygen (O) is responsible for cellular respiration in plants. This element plays a critical role in photosynthesis and is both stored for energy and released as a byproduct.

What is photosynthesis in one word answer?

Plants absorb sunlight and turn that energy into food; the process is known as photosynthesis. This is a compound word made up of photo (which means “light”) and synthesis (which means “to put together”).

Why does photosynthesis release oxygen?

In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.

Where is oxygen made in plants?

The carbon dioxide that the plant uses to make glucose through photosynthesis is captured from the air through microscopic openings (“stomata”) in the plant’s outer tissue layer (“epidermis”). The stomata open and close as the plants absorb carbon dioxide and release oxygen.

What is oxygen function?

Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.

How is oxygen produced in plants?

Oxygen can be produced from a number of materials, using several different methods. The most common natural method is photo-synthesis, in which plants use sunlight convert carbon dioxide in the air into oxygen. This offsets the respiration process, in which animals convert oxygen in the air back into carbon dioxide.

What is photosynthesis kid definition?

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. Interactive. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas …

What is photosynthesis class 7th?

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.

Does photosynthesis require oxygen?

The quick answer to your question is that oxygen is just a waste product when plants do photosynthesis. Plants can do two important things: Use energy from the sun to turn CO 2 (carbon dioxide) and H 2 O (water) into sugar (C 6 H 12 O 6) with oxygen (O 2) left over. This is photosynthesis. And they can: Break down the sugar (C 6 H 12 O 6) into CO 2 (carbon dioxide) and H 2 O (water), but they need (O 2) oxygen to do it.

What is the basic process of photosynthesis?

– Photosynthesis is a/an _______________ process. – _______________ colour of light is responsible for photosynthesis in bacteria. – Which metal is present in both chlorophyll “a” and “b”?

Why is photosynthesis considered an endergonic?

Is photosynthesis Endergonic or Exergonic What is the energy source that drives it? Photosynthesis is an endergonic reaction. Plants get the required energy—686 kcal to make a mole of glucose—from the environment by capturing light and converting its energy into chemical energy.

What are facts about photosynthesis?

The process. Photosynthesis has two main sets of reactions (phases).
