Light Dependent Reactions
Light Independent Reaction

the process by which

green plants and certain other organisms transform light

energy into chemical energy. During photosynthesis in green

plants, light energy is captured and used to convert water,
carbon dioxide, and minerals into oxygen and energy-rich

organic compounds

Photosynthesis

an organism that can produce its own

food using light, water, carbon dioxide, or other chemicals.

Because autotrophs produce their own food, they are

sometimes called producers.

Autotroph

an organelle within the cells of plants
and certain algae that is the site of photosynthesis, which is
the process by which energy from the Sun is converted into

chemical energy for growth

Chloroplast

a pigment present in all green plants
and a few other organisms. It is required for photosynthesis,
which is the process by which light energy is converted into
chemical energy. The chlorophyll pigment is responsible for

the green colouration in plants.

Chlorophyll

-Process by which green plants and certain other organisms transform light energy into chemical energy.

one of a group of carbohydrates
known as simple sugars (monosaccharides). It is a product
of photosynthesis.

Glucose

a coin-shaped stack of thylakoids, which are the
membrane-like structures found inside the chloroplasts of plant
cells. Photosynthesis, or the process by which plants make their
own food, occurs in the chloroplasts. Grana, or groups of granum,

are connected by way of stromal thylakoids.

Granum

membrane-bound compartments inside

chloroplasts and cyanobacteria. They are the site of the
light-dependent reactions of photosynthesis. Thylakoids
consist of a thylakoid membrane surrounding a thylakoid

lumen.

Thylakoid

the cells and tissues that support and give
structure to organs, glands, or other tissues in the body. The
stroma is mostly made up of connective tissue, blood vessels,

lymphatic vessels, and nerves. It provides nutrients to the

tissue or organ and removes waste and extra fluid.

Stroma

(LDRs) are a series of chemical reactions that occur during
the first stage of photosynthesis, converting light energy into

chemical energy. These reactions take place in plants and

other photosynthetic organisms

Light Dependent Reactions

also known as the Calvin cycle or dark reactions, are a series of

chemical reactions in photosynthesis that convert carbon

dioxide and other compounds into glucose. They occur in the

stroma, a fluid-filled region of a chloroplast outside the thylakoid

membranes, where the light-dependent reactions take place

Light Independent Reactions
