Chloroplast structure and function

System of 3 membranes

Outer membrane, inner membrane and thylakoid

Stroma

Part of the chloroplast that contains enzymes which control the reaction of the carbon fixation stage

Photosystems

Photosynthetic pigments ate arranged into photosystems, which allow maximum absorption of light energy

Stroma contains...?

Starch grains, and ribosomes

What do light independent reactions do ?

Turn CO2 into carbs

Chloroplast size

Varies from species to species

How are thylakoids arranged ?

in stacks called grana

Proteins

located inside the grana which holds the photosystems together

What do light dependent reactions do ?

Provide energy, NADPH and ATP for light independent reactions

Chloroplast function

Absorbs sunlight and converts it into sugar molecules and also produce free energy stored in the form of ATP and NADPH through photosynthesis

Grana

Known as thylakoids, contains pigments, and is responsible for the absorption of light energy

Chloroplast structure

It's surrounded by a double membrane, inside is a fluid filled region called the Stoma and stacks of membrane called grana

What kind of cell is chloroplast found in ?

It's the structure in a green plant cell which is where photosynthesis occurs.

what are 2 reactions of photosynthesis ?

Light Independent reactions & Light Dependent reactions
