chlorophyll
Definition
Chlorophyll is a green pigment found in the chloroplasts of plants and algae.
It is a complex molecule that contains magnesium, carbon, hydrogen, oxygen, and nitrogen.
Chlorophyll absorbs light energy from the sun, which is then used to power photosynthesis. Photosynthesis is the process by which plants convert carbon dioxide and water into glucose and oxygen. Glucose is a sugar that plants use for energy, while oxygen is released into the atmosphere.
How can the word be used?
Chlorophyll is essential for photosynthesis, the process by which plants convert sunlight into energy.
Different forms of the word
Noun:
Singular: chlorophyll.
Plural: chlorophylls.
Etymology
Sure, the word “chlorophyll” comes from the Greek words “chloros” and “phyllon”. “Chloros” means “green” and “phyllon” means “leaf”. The word “chlorophyll” was first used in English in the 19th century.

AQA Science Exam Question and Answer
Question:
What is chlorophyll, and what role does it play in the process of photosynthesis?
Answer:
Chlorophyll is a green pigment found in the chloroplasts of plant cells and some photosynthetic microorganisms. It is essential for the process of photosynthesis, as it absorbs light energy from the sun. During photosynthesis, chlorophyll captures this light energy and converts it into chemical energy, which is used to synthesize glucose (a form of sugar) from carbon dioxide and water. This process occurs in the presence of sunlight and is crucial for the survival of plants and the production of oxygen in the atmosphere.
