Photosynthesis Overview

Photosynthesis is the biochemical process by which green plants, algae, and some bacteria convert light energy, typically from the sun, into chemical energy stored in glucose, using carbon dioxide and water as raw materials, while releasing oxygen as a byproduct. This process occurs primarily in chloroplasts, utilizing chlorophyll to capture light energy.

Overview

Photosynthesis is a vital biological process that enables plants, algae, and some bacteria to convert light energy into chemical energy. This process not only produces glucose, which serves as food for the plant, but also releases oxygen, which is essential for the survival of most living organisms ...

Key Terms

Photosynthesis
The process by which plants convert light energy into chemical energy.

Example: Photosynthesis allows plants to produce their own food.

Chlorophyll
A green pigment in plants that absorbs light energy.

Example: Chlorophyll is what makes leaves green.

Glucose
A simple sugar produced during photosynthesis.

Example: Plants store energy in the form of glucose.

Oxygen
A gas released as a byproduct of photosynthesis.

Example: Humans and animals breathe in oxygen produced by plants.

Light-dependent Reactions
The first stage of photosynthesis that requires light.

Example: Light-dependent reactions occur in the thylakoid membranes.

Calvin Cycle
The second stage of photosynthesis that does not require light.

Example: The Calvin Cycle takes place in the stroma of chloroplasts.
