Overview

Chloroplasts are vital organelles in plant cells responsible for photosynthesis, a process that converts light energy into chemical energy. This process not only produces glucose, which serves as food for plants, but also releases oxygen, essential for most living organisms. Understanding chloroplas...

Key Terms

Chloroplast
An organelle in plant cells that conducts photosynthesis.

Example: Chloroplasts contain chlorophyll, which gives plants their green color.

Photosynthesis
The process by which green plants use sunlight to synthesize foods.

Example: Photosynthesis occurs in chloroplasts.

Chlorophyll
A green pigment found in chloroplasts that absorbs light energy.

Example: Chlorophyll absorbs blue and red light.

ATP
A molecule that carries energy within cells.

Example: ATP is produced during the light-dependent reactions.

NADPH
An electron carrier involved in photosynthesis.

Example: NADPH is used in the Calvin Cycle.

Thylakoid
Membrane-bound compartments inside chloroplasts where light-dependent reactions occur.

Example: Thylakoids are stacked in structures called grana.
