Photosynthesis

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Chlorophyll is the primary pigment found in plants that absorbs light energy for photosynthesis.

The general equation for photosynthesis is: 6CO₂ + 6H₂O → 6O₂ + C₆H₁₂O₆.

Leaves appear green because chlorophyll reflects green light and absorbs other wavelengths of light for photosynthesis.

No, animal cells do not have chloroplasts; they are found in plant cells.

Sunlight provides the energy required for the photosynthesis process, allowing plants to convert carbon dioxide and water into glucose and oxygen.

Photosynthesis uses sunlight to produce glucose, while chemosynthesis is a process used by some bacteria to produce glucose without sunlight, using chemical reactions.

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Oxygen (O₂) is produced as a byproduct of photosynthesis.

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for plants and, indirectly, for animals.
