•What pigments did you observe in the spinach leaf? The
coleus leaf?
•How are the two leaves different?
•When you look outside in the Fall you see many vibrant
colors like red, yellow, orange, and yellow. Where do you
think these colors were during the summer?
•How can they suddenly appear in autumn?

P4, P5: The Nature of Light

White light from the sun is composed of a
range of wavelengths (colors).
P4, P5: The Nature of Light

Different colors are actually different
wavelengths; violet is the shortest
wavelength (and most energy) and red is
the longest (and least energy)

Answer the following on a lined piece of paper:
 What
do pigments do for plants?
 What
are the colors that make up the visible spectrum
(the same colors that make up a rainbow)?
 What

Why?
 What

color does chlorophyll make plants?
colors do the carotenoids make plants?
Why? When do we see these colors?
P4: Pigments

Pigments are molecules that absorb
different wavelengths of light.
P4, P5: Chlorophyll and Light

Chlorophyll is the main
photosynthetic pigment.

Plants are green because
of the presence of this
pigment; the pigment
REFLECTS green light
and absorbs all others.

What about in fall?
P4, P5: Carotenoids

In the fall, chlorophyll is
broken down and the
carotenoids are exposed.
Practice with Pigments

Why are plants green in the spring/
summer?
They absorb blue and red light, and reflect
green light.
B. They absorb blue and green light, and
reflect yellow, orange, and red light.
C. They absorb green light, and reflect blue
light.
D. They absorb yellow, orange, and red light,
and reflect blue and green light.
A.
Practice with Pigments

Why aren’t plants green in the fall?
They absorb blue and red light, and reflect
green light.
B. They absorb blue and green light, and
reflect yellow, orange, and red light.
C. They absorb green light, and reflect blue
light.
D. They absorb yellow, orange, and red light,
and reflect blue and green light.
A.
Practice with Pigments

Why aren’t plants green in the fall?
Chlorophyll is expressed at a high level.
B. The carotenoids aren’t expressed.

carotenoids are expressed the most.
D. They are never green.

Groups

Get into groups of NO MORE THAN 3.

This will be your group for all of
Photosynthesis/ and Cellular Respiration.

Be sure to get with people that you can be
successful with.
The Flipped Classroom
 What
is a flipped classroom?
 What
is the point?
 How
are we going to flip the class?
First Flipped Class Lesson

Watch ATP video on Youtube
 Look
it up or access it through weebly

Create your own notes

Get with your group and be sure that you
have everything that you need.
As you enter, PLEASE

Get out your notes.

You may discuss your notes with your
group to fix any inconsistencies or modify
your notes in any way.

THIS IS NOT A TIME TO COPY YOUR
PARTNERS NOTES.
P7: ATP
Data Collection

Did it work?

Critique your experiment and 1 other groups.

Why do you think it did or didn’t work. Be sure to
use your knowledge about photosynthesis.

How would you change the experiment to fix
this?
Photosynthesis Project

Due: Wednesday at the end of class.

Create a poster that will demonstrate the light-dependent and
independent reactions of photosynthesis.

Must include the following: (chloroplast, chlorophyll, thylakoid,
stroma, light-dependent reactions, light, electrons, electron transport
chain, NADP+, NADPH, protons, ADP + P, ATP, water, oxygen,
light-independent reactions, carbon dioxide, and glucose)

You may use your notes, your book, and/ or the internet.

All people in the group must be able to explain the process.
P6: Light-Dependent Reactions

Light strikes chlorophyll and excites an electron to
a higher energy state.
 (P3)


The sun provides all energy found in the
environment.
Electrons are
excited.
These electrons
are moved to the
electron
transport chain
where they
produce NADPH
from NADP+.
P6: Light-Dependent Reactions

These electrons must be
replaced.

H2O is split into H and O.

The electrons from H
replace the excited
electrons.

O combines to make O2.

This is the waste of
photosynthesis.
P6: Light-Dependent Reactions

The H are used by the ATP
synthase to combine a
phosphate with ADP to
make ATP.
P8: Light-Independent Reactions


Known as the Calvin Cycle
Phosphates are broken off of ATP and electrons are
removed from NADPH which provides the energy to turn
CO2 to glucose (C6H12O6)
 It takes six cycles to do this
As you enter, PLEASE

Get out your notes.

Finish collecting your data from the
Photosynthesis experiment.
 Develop

a conclusion.
Was your hypothesis correct? Use data and your
knowledge of photosynthesis to prove your
conclusion.
 Turn
in one lab document per group.
