Photosynthesis

Photosynthesis

Photosynthesis takes in carbon dioxide, light, and water to produces sugar and oxygen

• light-dependent and

• light-independent steps.

Photosynthesis

Photosynthesis takes place in chloroplasts found in

plant leaves.

Chloroplast contain

grana, stroma,

lamella, and

thylakoid

membranes

Chlorophyll- green
pigment found in
chloroplast that

absorbs light energy

from the sun

Granum - stacks of

structures covered in the

thylakoid membrane.

This is the site of the Light

Dependant reaction.

Thylakoid -

membrane around
the granna where

photosynthesis

takes place

Stroma-fluid around

the granum that

contains enzymes,

chloroplast DNA, and
ribosomes . Site of the

Light Independent

Reaction

Outer Membrane -

Semi-permeable

and holds the

chloroplast

together.

Inner Membrane -

Surround the

stroma and

ganum. Helps

direct molecules

ATP - Adenposine

Triphosphate-

energy molecules

● In the grana, sunlight is

caught by chlorophyll,
which allows for the
photophosphorylation of
ADP (to make ATP) and the
production of NADPH.

In the stroma, ATP and

photosynthesis turns

carbon dioxide and water

into carbohydrates and oxygen.

Light Dependent -

What goes in (reactants)? - water, sunlight

What comes out (products)? - Oxygen, NADPH, and ATP

Where? - Thylakoid

Light Inependent -

What goes in (reactants)? - Carbon Dioxide

What comes out (products)? - Glucose

Where? - Stroma
