Photosynthisis

6H20 + 6CO2 + Light Energy --> C6H2O6 + 602
Photosynthesis
is a process used by plants and other organisms to convert light energy, normally from the sun, into chemical energy that can be used to fuel the organisms' activities.

Light Dependent: First stage of photosynthesis. A process by which plants capture and store energy from the sunlight.

Light Independent: Chemical Reactions that convert carbon dioxide and other compounds into glucose.

Photosynthesis is the only most significant natural process to convert CO2 to O2.

Not only photosynthesis helps to balance the Oxygen content of the atmosphere but also it helps energy balance in the ecosystem.

Chloroplast

Chloroplasts are the sites of photosynthesis. These double-membrane bound organelles enclose additional membranes called thylakoids. The disc-shaped thylakoids possess an interior space. The thylakoids are stacked to form grana, which are suspended in the stroma of the chloroplasts. Demonstrate your knowledge of chloroplast structure by placing the labels in their correct locations.

Membranes: Protects the place.

Stroma: It sucks up Carbon Dioxide, and Water.

Thylakoid: each of a number of flattened sacs inside a chloroplast, bounded by pigmented membranes on which the light reactions of photosynthesis take place, and arranged in stacks or grana.

Granum: A stacked membranous structure within a chloroplast that contains the chlorophyll and is the site of the light reactions of photosynthesis.

Lamellae: Its skin over the membrane.

Chlorophyll: Any of a group of green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria, especially

Summary: Chloroplasts and photosynthetic bacteria obtain high-energy electrons by means of photosystems that capture the electrons that are excited when sunlight is absorbed by chlorophyll molecules. Photosystems are composed of an antenna complexthat funnels energy to a photochemical reaction center, where a precisely ordered complex of proteins and pigments allows the energy of an excited electron in chlorophyll to be captured by electron carriers.
