Daily Objective:
By the end of today I should be able to…
•Explain the difference between Autotrophs
and Heterotrophs
•Describe the way in which energy is stored
and released using ATP
Entrance task:
In your notebook, taking up a little less than half
of the page, write out the equations on the board
to the right.
What do you notice about
the two equations?
 How are they related?
Vocab Review
 I have underlined the things that you
should be sure to WRITE DOWN 
Autotrophs
 Organisms that make their
own food. They do not rely on
other organisms to get
nutrients
Example: Plants
PHOTOAUTOTROPHS
 Use Light energy from the sun to
produce food
Heterotrophs
 Organisms that obtain
energy from the food
they consume
Example: a cow eats
grass and grass is
autotrophic
Producers and Consumers
 Producers: The source
of organic compounds
for all nonautotrophic
organisms
 Consumers: Live on
compounds produced by
autotrophs.
Energy in general…
ATP
 Everything that occurs in the cell is
powered by chemical fuels
 The main energy storage compound for
living things is:
ADENOSINE TRIPHOSPHATE
Adenine
Ribose
3 Phosphate groups
ADP
 Adenosine Diphosphate
 Has 2 phosphates instead of 3
 Cells can store energy by
adding a phosphate group to
ADP Molecules
This energy is
used by the
Cell for many
different cell
Processes
•ACTIVE
TRANSPORT
•MOVEMENT
Energy
Take the next 6-7 minutes to
describe how ATP works… In
your paragraph, explain what
ATP is able to do, and how it
accomplishes its job.

Daily Objective:
By the end of today I should be able to…
•Explain how the understanding of
photosynthesis developed
Entrance task:
Grab a sheet off of
the front stool
and read through
and label it.

 Can store 90
times more
energy than
ATP
IV. Investigating
Photosynthesis
 Research into the
processes of
Photosynthesis began with
a simple question…
 How does a small seed
become a towering tree???
IV. Investigating
Photosynthesis
 Van Helmont – 1600’s
 Wanted to know if Plants
take material from the soil.
 Grew a plant for 5yrs.
 Noticed that the mass of
the soil really didn’t change.
 So where did the mass come
from???
IV. Investigating
Photosynthesis
 Priestley – 1700’s
 Took a candle and noticed
this…
 Noticed that if a plant was
placed in the chamber, the
flame took longer to die…
So what did the plants produce???
IV. Investigating
Photosynthesis
 Ingenhousz
 Took Priestley’s
Experiment and showed
that plants only produce O2
when exposed to light.
 So what 3 things did these
experiments link???
IV. Investigating
Photosynthesis
 So the main point is…
 These experiments
showed that plants use CO2
and H2O to make O2 and
Carbohydrates.
 What Organelle is
responsible???

Daily Objective:
By the end of today I should be able to…
•Explain how plant cells use photosynthesis to
produce their own food.
Entrance Activity:
Please quietly Draw and Label a chloroplast in your
notebook. (It should take up about half a page.) A chloroplast
can be found on Page 233.
When you are finished, please review your notes from
yesterday.
VI. Plant Structure
 Plants also need a way to
absorb the light. Light
absorbing molecules are
called pigments. In plants, the
pigment is called chlorophyll.
 Chlorophyll absorb light in
the blue and red
wavelengths.
VI. Plant Structure
Absorption of Light by
Chlorophyll a and Chlorophyll b
Photosynthesis is….
 The use of light energy to produce high
energy molecules like glucose
Does photosynthesis transform light into
food?
VII. Two parts to
photosynthesis
1. Light-dependent reactions Thylakoid:
uses light and water to produce
oxygen and high energy carriers
(ATP)
2. Light-independent reactions stroma
(Calvin cycle): Uses ATP and CO2 to
produce high energy sugars. These
sugars are able to store energy
better than ATP and.
HIGH ENERGY CARRIERS
 ATP = adenosine triphosphate
 NADPH = nicotinamide adenine
dinucleotide phosphate
NADPH
 When NADP+ picks up a hydrogen ion
from the water taken in during
photosynthesis, it traps high energy
electrons in the bond between NADP and
H
Light Reaction (Thylakoid)
 Sunlight and water enter the chloroplast
 The sunlight excites high energy electrons
in the chlorophyll and water molecules are
broken into Hydrogen ions (H+) and O2
molecules
 The oxygen is released and
 NADP+ picks up 2 high energy electrons and
a hydrogen to become NADPH
 ADP + P also picks up a high energy electron
to become ATP
 Both carriers now move out of the Thylakoid
and into the Stroma of the chloroplast
The Dark Reaction: Calvin Cycle
 In the stroma, CO2 from the
atmosphere, NADPH, and ATP are
used to make high energy sugars
