Photosynthesis

these sustain themselves without eating anything derived from other organisms

Autotrophs

Use energy of sunlight to make organic molecules from H2O and CO2

Phototrophs

Organelles in cells of leaves that allows for chemical reaction of Photosynthesis

Chloroplasts

Main site/location of plant that photosynthesis occurs

the leaves

This is absorbed by chlorophyll and drives synthesis of organic molecules in chloroplasts

Light energy

Chloroplasts are found in what type of cells, that are the interior tissue of the leaf

Mesophyll

Mesophyll can have how many chloroplasts per cell?

30 - 40

Chlorophyll is found in the membrane of

the thylakoids

These are connected sacs in chloroplasts

thylakoids

thylakoids are stacked in columns called

grana

The densee fluid contained in chloroplasts is called

stroma

What is reduced and what is oxidized in Photosynthesis

H2O is oxidized and CO2 is reduced

What are the two parts of photosynthesis

Light reaction
Calvin Cycle

Where does the light reaction process occur

in the thylakoid

Where does the calvin cycle occur

in the stroma

___ is called electromagnetic engergy or radiation

Light

absorbs visible ligt

pigments

wavelengths that are not absorbed are (2 things)

transmitted or reflected

the main photosynthetic pigment

chlorophyll a

name 2 accessory pigments

chlorophyll b, caratenoids

2 parts of photosystem

reaction center complex
light harvesting complex

protein complex where electron transfer happens

Reaction center complex

Surrounds reaction center, pigment molecules bound to proteins that funnel energy of photons to reaction center

Light harvesting Complex

Accepts the excited electron in reaction center

Primary electron acceptor

Photosystem that absorbs at 680nm

Photosystem II

Photosystem that absorbs at 700nm

Photosystem I
