Did you know plants can turn sunlight into food? It’s all thanks to a process called photosynthesis.
To understand it, you need to know a few key words. From ‘chlorophyll’ to ‘oxygen,’ these terms explain how plants grow and help the planet. Let’s explore the basic photosynthesis words and definitions.
What is Photosynthesis?
Photosynthesis Definition:
Photosynthesis refers to the process by which plants use energy from sunlight to make their own food (glucose) from carbon dioxide in the air and water from the soil.
Photosynthesis Words and Definitions
Here are over 15 words related to photosynthesis with their definitions:
Below is a photosynthesis words list:
Chlorophyll
The green pigment in plants, algae, and some bacteria that absorbs light energy needed for photosynthesis.
Chloroplast
Organelles found in plant cells where photosynthesis takes place. They contain chlorophyll.
Carbon dioxide (CO₂)
A colorless gas that plants absorb from the air and use as a raw material for photosynthesis.
Oxygen (O₂)
A gas released as a byproduct of photosynthesis, essential for respiration in most living organisms.
Glucose
A simple sugar (C₆H₁₂O₆) produced during photosynthesis, which serves as energy and a building block for growth in plants.
Light energy
Energy from the sun or artificial light that drives the photosynthesis process by energizing electrons in chlorophyll.
Sunlight
The natural source of light energy that provides the energy plants need for photosynthesis.
Water (H₂O)
A key reactant in photosynthesis, absorbed by plant roots and split into oxygen and hydrogen during the process.
Stomata
Small pores on the surface of leaves that allow carbon dioxide to enter and oxygen to exit during photosynthesis.
Energy
The ability to do work. In photosynthesis, light energy is converted into chemical energy stored in glucose.
Autotrophs
Organisms, such as plants and algae, that can produce their own food through photosynthesis or other processes.
Leaves
The primary site of photosynthesis in most plants, containing chloroplasts and specialized structures for gas exchange.
Pigment
A substance that absorbs light; in plants, chlorophyll is the main pigment used for photosynthesis.
Thylakoid
Disk-shaped structures inside chloroplasts where light-dependent reactions of photosynthesis occur.
ATP (Adenosine Triphosphate)
A molecule that stores and transfers energy within cells, produced during the light-dependent reactions of photosynthesis.
NADPH
An energy-carrying molecule produced in the light-dependent reactions and used in the Calvin Cycle to make glucose.
Calvin Cycle
The set of light-independent reactions in photosynthesis where carbon dioxide is converted into glucose using ATP and NADPH.
Light-dependent reactions
The first stage of photosynthesis that occurs in the thylakoids, where light energy is used to produce ATP and NADPH.
Light-independent reactions
Also called the Calvin Cycle, this stage occurs in the stroma of the chloroplast and does not require light, using ATP and NADPH to make glucose.
Photolysis
The process during light-dependent reactions where water molecules are split into oxygen, hydrogen ions, and electrons.
