The meaning of the term photosynthesis is the process by which green plants manufacture their food (sugar) through the use of inorganic substances and sunlight as a source of energy.
Before photosynthesis takes place in a green plant, there must be presence of inorganic substances such as:
- water
- carbondioxide and
- sunlight (energy source).
The energy from sunlight is captured by the pigment called chlorophyll which is present only in green plants.
The products of photosynthesis is simple sugars with the giving off of oxygen as a by-product.
Therefore, photosynthesis is the process by which green plants manufacture their food (sugar) through the use of inorganic substances and sunlight as a source of energy.
