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.
How does photosynthesis work in algae?
As a general rule, algae are capable of photosynthesis and produce their own nourishment by using light energy from the sun and carbon dioxide in order to generate carbohydrates and oxygen.
What is photosynthesis in biology class 9?
Photosynthesis is a physiological process by which plant cells containing chlorophyll produce food in the form of carbohydrates by using carbon dioxide, water and light energy. Oxygen is released as a by-product.
How do plants photosynthesize?
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 class 6th?
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.
What is photosynthesis process Class 10?
Photosynthesis is the physico-chemical process by which plants can convert light energy into chemical energy, in the form of carbohydrate from simple inorganic substances like atmospheric carbon dioxide and water. Photosynthesis requires carbon dioxide, sunlight, water and chlorophyll as its basic raw materials.
What is photosynthesis and how does it work?
What is photosynthesis? 1 Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive. 2 Carbon dioxide, water and light are all needed for photosynthesis to take place. 3 Photosynthesis happens in the leaves of a plant. More
How do plants take in carbon dioxide for 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). Carbon dioxide enters through the stomata on the underside of the leaf. Water is absorbed by the root hair cells and is transported to the leaf by the xylem vessels.
What is the meaning of the root word photosynthesis?
The Greek roots of photosynthesis combine to produce the basic meaning “to put together with the help of light”. Photosynthesis is what first produced oxygen in the atmosphere billions of years ago, and it’s still what keeps it there.
What was the Underground Railroad and how did it work?
During the era of slavery, the Underground Railroad was a network of routes, places, and people that helped enslaved people in the American South escape to the North. The name “Underground Railroad” was used metaphorically, not literally. It was not an actual railroad, but it served the same purpose—it transported people long distances.
