photosynthesis

Foundational review and new details

Photosynthesis Basics

• CO₂+H₂O+Sunlight>>>C₆H₁₂O₆+O₂

• Happens in chloroplast

• Happens in plants (autotrophs)

Multiple Select

What are the reactants of photosynthesis?

• H2O

• CO2

• C6H12O6

• O2

Multiple Select

What are the products of photosynthesis?

• H2O

• CO2

• C6H12O6

Chloroplast Basics

• Only found in plants

• Two major parts

• Grana (made of thylakoids)

• Stroma (space between grana)

Multiple Choice

The grana is made up of which of the following?

• Chloroplasts

• Chlorophyll

• Thylakoids

• Stroma

Leaf Structure Basics

• Cuticle: keeps water in

• Epidermis: protection

• Palisade mesophyll: photosynthesis

• Spongy mesophyll: gas storage & exchange

• Stomata: gas exchange

Multiple Choice

• Spongy

• Epidermis

Multiple Choice

Where does CO2 enter the leaf and O2 exit the leaf?

• Cuticle

• Epidermis

• Stoma or Stomata

• Central Vein

Photosynthesis Details

Now that you have reviewed what photosynthesis is, where it happens and what it needs and produces, you will look at how it does this. Use your photosynthesis details ppt to take notes from the black slides.

Photosynthesis

• The process of capturing energy from sunlight to make glucose that stores energy

• Occurs (happens) on a chlorophyll (photosystem) molecule molecule, that is on a thylakoid, that is in a stack of grana

Photosynthesis has 2 parts

• Light Dependent (needs light)

• Light Independent (doesn't need light)

Multiple Select

What are the two parts to photosynthesis?

• Light Dependent

• Light Independent

• Light Saber

• Cellular Respiration

Light Dependent Reactions

• Happens in thylakoid

• On chlorophyll (pigment) molecules

• Takes in H2O

• Sunlight energy breaks apart H2O

• Releases O2

• Uses light and H (from water) to make ATP and NADPH

Multiple Select

Which reactants of photosynthesis are needed for the light dependent reactions?

• CO2

• H2O

• C6H12O6

• O2

• Light

Multiple Choice

Which of the two photosynthesis products are made by the light dependent reaction

• CO2

• H2O

• C6H12O6

• O2

Multiple Select

Besides O2 (oxygen) what else is produced (made) by the light dependent reactions?

• CO2

• ATP

• NADPH

• C6H12O6

Light Independent Reactions

• Sometimes called "Calvin Cycle"

• Happen in the stroma

• Uses ATP & NADPH from light dependent

• Uses CO2

• Makes C6H12O6 (glucose)

Multiple Select

What is used during the light independent reactions that was made during the light dependent reactions?

• O2

• ATP

• NADPH

• CO2

Multiple Choice

Which reactant of photosynthesis is used in the light independent reaction?

• CO2

• H2O

• O2

• Light

Multiple Choice

What is produced by the light independent reaction?

• CO2

• H2O

• O2

• C6H12O6

Photosynthesis Breakdown

• Light Dependent: Takes in sunlight and H2O into the thylakoid

• Produces O2, ATP & NADPH

• Light Independent: Takes in CO2, ATP & NADPH in the stroma

• Produces C6H12O6
