Slide 11
CATALYST 2: PLANTS NEED THREE THINGS TO GROW, WHAT ARE THEY?
Sunlight Water H 2 O Carbon dioxide CO 2
Slide 12
PLANTS NEED THREE THINGS TO GROW, WHAT ARE THEY? Sunlight
(energy) Water (liquid) Carbon dioxide CO 2 (gas) Is soil anywhere
in the equation for photosynthesis? Nope Why would plants need a
gas to grow???
Slide 13
CHEMICAL EQUATION FOR PHOTOSYNTHESIS What do the big numbers
mean? Number of MOLECULES ex: 6 CO 2 = CO 2 CO 2 CO 2 CO 2 CO 2 CO
2 What do the little numbers mean (subscript)? Number of ATOMS of
an element that are part of the molecule. Ex: CO 2 = O---C---O What
do the letters mean? The type of ELEMENT C= Carbon, H=Hydrogen,
O=Oxygen What is the Law of Conservation of Matter? Matter (stuff)
cannot be created or destroyed. All of the stuff (matter) you start
a chemical reaction with has to be there when the reaction is done.
Reactants must equal products! (equation must balance) Reactants
Products

CATALYST: WHAT IS A PRODUCT OF THE LIGHT-DEPENDENT REACTIONS?
Agenda Catalyst Homework review Catch up Objectives SWBAT Explain
the inputs and outputs of the light independent and light dependent
reactions of photosynthesis.
Slide 29
HOMEWORK REVIEW 1)What colors of light are present in white
light? ROYGBIV 2)What colors of light are absorbed by chlorophyll a
and chlorophyll b? Blue-Violet & red 3) Use your answer to
question 2 to explain why plants are green. (dont just say b/c the
reflect green light EXPLAIN why that happens) According to figure
8-4 chlorophyll a and b in plants does not absorb the green-yellow
light frequencies as well as the blue-violet and red frequencies.
Therefore, plants reflect mostly green light which is what makes
them appear green in color.
Slide 30
4)What is the name of the organelle that's present in
Eukaryotic organisms that allow the cell to photosynthesize?
Chloroplast 5)In what specific structure within that organelle does
photosynthesis take place? Thylakoids 6)When plants absorb light
energy where do they immediately transfer that energy two? (hint:
its part of an atom) Electrons!
Slide 31
7) What are high-energy electron carrier molecules? NADPH &
NADP+ 8) Explain the function of NADPH and NADP+ An electron
carrier is a compound that can accept a pair of high-energy
electrons and transfer them, along with most of their energy, to
another molecule.
Slide 32

CATALYST: WHAT IS THE CHEMICAL EQUATION FOR PHOTOSYNTHESIS?
Agenda Catalyst Plant energy Life Energy Cellular Respiration
Objective: Identify the reactants and products of cellular
respiration.
Slide 53
ENERGY FROM PLANTS ENERGY FOR LIFE The Sun is the main source
of energy for life on the planet Through photosynthesis plants
store the suns energy in the BONDS of the glucose molecule. What is
a chemical bond? An electrical attraction between two atoms The
Suns energy is stored in the BONDS of glucose Anything that eats
plants is capable of using that stored energy The organism then
uses the energy to produce ATP
Slide 54
WHAT IS ATP??? ATP stands for Adenosine Triphosphate This
molecule is the energy currency of your cells. ALL cells use ATP
for energy and regulating metabolism. (how fast you burn energy)
ATP is like a glow stick, it has to get broken to release its
energy
Slide 55
CELLULAR RESPIRATION The process by which a living thing gets
energy from breaking down glucose is called cellular
respiration.
Slide 56
CHECK FOR UNDERSTANDING QUESTIONS 1. What are the products of
photosynthesis? 2. What are the reactants of cellular respiration?
3. What are the products of cellular respiration? 4. What are the
reactants of photosynthesis? 5. What do you notice about these two
processes? 6. How are photosynthesis and cellular respiration
similar? Different? 7. Suggest one reason these two process need to
be connected.
