CATALYST 2: PLANTS NEED THREE THINGS TO GROW, WHAT ARE THEY? Sunlight Water H 2 O Carbon dioxide CO 2

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???

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.

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.

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!

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.

Write the equation for photosynthesis 6CO 2 + 6H 2 O + Sunlight C 6 H 12 O 6 + 6O 2 Identify the reactants and products of the photosynthesis equation. The reactants are: Carbon Dioxide, Water and Sunlight The products are: Glucose and Oxygen What is ATP??? Adenosine triphosphate = ATP This is the molecule that is the direct source of energy for cells. Cells can crack it in half (like a glow stick) and it will release stored energy.

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.

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

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

CELLULAR RESPIRATION The process by which a living thing gets energy from breaking down glucose is called cellular respiration.

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.
