Photosynthesis
. Definition
Photosynthesis is the process by which green plants, algae, and some bacteria make their own food. It uses sunlight, carbon dioxide, and water to produce glucose (sugar) for energy. This process is also very important because it releases oxygen into the air, which all living beings need to survive.
. Where it does and How it does
Photosynthesis takes place in the leaves of plants, inside cell parts called chloroplasts. The green pigment chlorophyll absorbs sunlight. The roots of the plant take in water from the soil, and the leaves absorb carbon dioxide from the air. Using the energy of sunlight, the plant combines water and carbon dioxide to form glucose. Oxygen is released as a byproduct into the atmosphere.
. Essential things
The important things required for photosynthesis are:
Sunlight
Water
Carbon dioxide
Chlorophyll (green pigment in leaves)
Chloroplasts (where the process happens)
. Key words
Photosynthesis
Chlorophyll
Glucose
Oxygen
Carbon dioxide
Chloroplast
notes :
photosynthesis is a process of making food for the plants
photo means light and synthesis is process . “Plants take in oxygen and release carbon dioxide during photosynthesis.”.“Plants take in carbon dioxide and release oxygen during photosynthesis.”
Give a simple definition of photosynthesis. In your own words.
In which part of the plant does photosynthesis mainly occur?
What is the function of chloroplasts in photosynthesis?
How does sunlight help in the process of photosynthesis?
From where do plants get the carbon dioxide needed for photosynthesis?
Which part of the plant absorbs water for photosynthesis?
What type of energy is stored in glucose produced during photosynthesis?
How does photosynthesis contribute to the balance of gases in the atmosphere?
Name the green pigment that makes leaves appear green.
Write four important requirements for photosynthesis.
The post itself without the video and note is short.
