Photosynthesis occurs in:

🔑Key Points:

✏️Photosynthesis:
-Photosynthesis definition states that the process exclusively takes place in the chloroplasts through photosynthetic pigments such as chlorophyll a, chlorophyll b, carotene, and xanthophyll.
-All green plants and a few other autotrophic organisms utilize photosynthesis is to synthesize nutrients by using carbon dioxide, water, and sunlight.
-The by-product of the photosynthesis process is oxygen.
-Photosynthesis occurs when plants use light energy to convert carbon dioxide and water into glucose and oxygen.
-Leaves contain microscopic cellular organelles known as chloroplasts.
-Each chloroplast contains a green-colored pigment called chlorophyll.
-Light energy is absorbed by chlorophyll molecules whereas carbon dioxide and oxygen enter through the tiny pores of stomata located in the epidermis of leaves.
-Another by-product of photosynthesis is sugars such as glucose and fructose.
-These sugars are used by the plants as an energy source, which helps them to grow.
-Photosynthesis also applies to other organisms besides green plants.
-These include several prokaryotes such as cyanobacteria, purple bacteria, and green sulfur bacteria.
-These organisms exhibit photosynthesis just like green plants.
-The glucose produced during photosynthesis is then used to fuel various cellular activities.
-The by-product of this physio-chemical process is oxygen.
