1. Get out Spiral - Warm Up: Being as detailed as you can, explain (in words your own words) what is happening in the diagram below

2. Rate yourself based on what you know about Photosynthesis
Scale 0-4
Rate yourself based on what you know about Photosynthesis 4
I can name organelles and structures used in photosynthesis, identify/name elements used in photosynthesis, write the equation for photosynthesis, and relate the equation to cellular respiration. 3
I can name the organelles and structures used in photosynthesis, identify and name the elements going in to photosynthesis, and write the equation for photosynthesis 2
I can identify some organelles and recognize the photosynthesis equation 1
I cannot explain or identify elements, organelles, structures, or the equation for photosynthesis

Photosynthesis: Life from Light and Air

4. All LIVING organisms need energy!
Organisms get energy either directly or indirectly from energy through sunlight in a process called photosynthesis
In your table (Groups of 2-3) come up with a definition for Photosynthesis

5. Organisms that photosynthesis are called Autotrophs
Photosynthesis: a process by which a cell captures energy in sunlight and uses it to make sugar (food).
Organisms that photosynthesis are called Autotrophs
Organisms that obtain energy by consuming autotrophs are called Heterotrophs

6. Draw a quick version of a plant in your spiral

Sugar (energy)
Reactant
Product
Reactant
The organelle responsible for photosynthesis is the Chloroplast

7. So what does a plant need?
Bring In
light
CO2
H2O
Let Out O2
Move Around
Sugars (energy)
leaves
shoot
roots
Brainstorm what the Chemical equation is  +
6CO2
6H2O
C6H12O6
6O2
light
energy  +

8. Stomates & Guard Cells guard cell stomate Function of stomates
CO2 in
O2 out H2O out
Function of guard cells– to open and close the stomata (hole)
LOCATED ON BOTTOM OF LEAVES!
open & close stomates

9. Guard cells & Homeostasis
keeping the internal environment of the plant balanced
Stomates open
let CO2 in
let H2O out
let O2 out
Stomates close
if too much H2O is evaporating

10. Get out Spiral – go back and re write or correct your warm up by explaining the photo below.

11. On the left hand side of your notebook complete the leaf diagram by correctly placing the arrows products and reactant in photosynthesis equation

13. How do plants make energy & food?
Plants use the energy from the sun
to make ATP energy
to make sugars
glucose, sucrose, cellulose, starch, & more
sun
ATP
sugars

14. Using light & air to grow plants
Photosynthesis
using sun’s energy to make ATP
using CO2 & water to make sugar
HAPPENS in chloroplasts
(ATP) = used to build the sugar
 glucose + oxygen
carbon
dioxide
sun
energy
+ water +
6CO2
6H2O
C6H12O6
6O2
sun
energy  +

15. What do plants need to grow?
The “factory” for making energy & sugars
chloroplast
Fuels
sunlight
carbon dioxide
water
The Helpers
enzymes
Make ATP! Make sugar! I can do it all…
sun
CO2
ATP
enzymes
sugars
H2O

16. Chloroplasts are only in plants
animal cells
plant cells

17. glucose + oxygen  carbon + water + energy
How are they connected?
Respiration
glucose + oxygen  carbon + water + energy
dioxide
C6H12O6
6O2
6CO2
6H2O
ATP  +
Photosynthesis
So, in effect, photosynthesis is respiration run backwards powered by light.
Cellular Respiration
oxidize C6H12O6  CO2 & produce H2O
fall of electrons downhill to O2
exergonic
Photosynthesis
reduce CO2  C6H12O6 & produce O2
boost electrons uphill by splitting H2O
endergonic
6CO2
6H2O
C6H12O6
6O2
light
energy  +
 glucose + oxygen
carbon
dioxide
sun
+ water +

19. The poetic perspective
All of the solid material of every plant was built out of thin air
All of the solid material of every animal was built from plant material
sun
air
Then all the cats, dogs, mice, people & elephants… are really strands of air woven together by sunlight!
