1. Wed/Thursday Block
Get out Mitosis packet and continue to work

2. Get out Spiral - Warm Up: Being as detailed as you can, explain (in words your own words) what is happening in the diagram below with your table members (page 48)
Critical Question: List the products and reactants of photosynthesis

3. Name organelles, elements, & the equation for photosynthesis
Goal:
Name organelles, elements, & the equation for photosynthesis
Relate the equation to cellular respiration.

4. Photosynthesis: Life from Light and Air
Remember to
Title
Number
& Update Table of Contents
Photosynthesis: Life from Light and Air

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

6. 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

8. Elements/Organelles involved
leaves
Bring In
Creates/Releases
Plants store the sugar in their structures (stem, leaves, roots)
Sunlight through chloroplast
Sugar
(ENERGGYY)
CO2 through stomata
O2 (oxygen) through stomata
H2O (water) through roots
H2O (water) through stomata

10. Guard cells & Homeostasis
Guard cells - curved cells that surround a stoma (hole) that maintains Homeostasis
internal environment of the plant balanced by…..
Stomata opening
let CO2 in
let H2O out
let O2 out
Stomata closing
if too much H2O is evaporating
guard cell
Stomata (the hole) underneath of the leaf

11. Draw a quick version of a plant in your spiral
Chloroplast-
Is the organelle responsible for photosynthesis
(located in the middle, inside of the leaf)
Thylakoid
Granum
Stroma (inner space)

12. Critical Question: List the products and reactants of photosynthesis

13. Leaf Diagram Add a picture for Energy - Fill in the blank (arrow) with the proper term - cut and glue the arrows to point to the proper location of where each description is happening

15. 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

16. 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

17. 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

18. Chloroplasts are only in plants
animal cells
plant cells

19. glucose + oxygen  carbon + water + energy
How are they connected?
Respiration
glucose + oxygen  carbon + water + energy

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

21. 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!
