Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas as raw materials. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.

Photosynthesis Site:

• Photosynthesis occurs in chloroplasts, which are unique organelles. Because this organelle has its own DNA and genes, it can produce its own proteins.
• The stroma, fluid, and grana comprise chloroplasts. Chlorophyll a, chlorophyll b, and carotenoids are three essential pigments that absorb light energy in the chloroplast.

Types of photosynthesis:

There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. The general principles of anoxygenic and oxygenic photosynthesis are very similar, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.
