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.
Slide 2
What do you notice about the two equations? How are they
related?
Slide 3
Vocab Review I have underlined the things that you should be
sure to WRITE DOWN I have underlined the things that you should be
sure to WRITE DOWN
Slide 4
Autotrophs Organisms that make their own food. They do not rely
on other organisms to get nutrients Example: Plants
Slide 5
PHOTOAUTOTROPHS Use Light energy from the sun to produce
food
Slide 6
Heterotrophs Organisms that obtain energy from the food they
consume Example: a cow eats grass and grass is autotrophic
Slide 7
Producers and Consumers Producers: The source of organic
compounds for all nonautotrophic organisms Consumers: Live on
compounds produced by autotrophs.
Slide 8
Energy in general
Slide 9
ATP Everything that occurs in the cell is powered by chemical
fuels The main energy storage compound for living things is:
ADENOSINE TRIPHOSPHATE You gotta know this!!!
Slide 10
AdenineRibose3 Phosphate groups
Slide 11
ADP Adenosine Diphosphate Has 2 phosphates instead of 3 Cells
can store energy by adding a phosphate group to ADP Molecules
Slide 12
Slide 13
Slide 14
This energy is used by the Cell for many different cell
Processes ACTIVE TRANSPORT MOVEMENT Energy
Slide 15
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.
Slide 17
III. Differences ATP Efficient at transferring energy Glucose
Efficient at storing energy Can store 90 times more energy than
ATP
Slide 18
IV. Investigating Photosynthesis Research into the processes of
Photosynthesis began with a simple question How does a small seed
become a towering tree???
Slide 19
IV. Investigating Photosynthesis Van Helmont 1600s Wanted to
know if Plants take material from the soil. Grew a plant for 5yrs.
Noticed that the mass of the soil really didnt change.
Slide 20
So where did the mass come from???
Slide 21
IV. Investigating Photosynthesis Priestley 1700s Took a candle
and noticed this Noticed that if a plant was placed in the chamber,
the flame took longer to die
Slide 22
So what did the plants produce???
Slide 23
IV. Investigating Photosynthesis Ingenhousz Took Priestleys
Experiment and showed that plants only produce O 2 when exposed to
light. So what 3 things did these experiments link???
Slide 24
IV. Investigating Photosynthesis So the main point is These
experiments showed that plants use CO 2 and H 2 O to make O 2 and
Carbohydrates. What Organelle is responsible???
Slide 25

_________________________________________________________ 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. Please have out your homework, but do not
turn it in yet
Slide 28
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.
Slide 29
VI. Plant Structure Absorption of Light by Chlorophyll a and
Chlorophyll b
Slide 30
Photosynthesis is. The use of light energy to produce high
energy molecules like glucose Does photosynthesis transform light
into food?
Slide 31
Slide 32
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 CO
2 to produce high energy sugars. These sugars are able to store
energy better than ATP and. VII. Two parts to photosynthesis
Slide 33
HIGH ENERGY CARRIERS ATP = adenosine triphosphate NADPH =
nicotinamide adenine dinucleotide phosphate
Slide 34
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
Slide 35
Slide 36
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 O 2 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
Slide 37
The Dark Reaction: Calvin Cycle In the stroma, CO 2 from the
atmosphere, NADPH, and ATP are used to make high energy sugars
Slide 38
