DO NOW: HAVE YOUR CELL PROJECT OUT!

1. What REACTANTS are needed for cellular respiration?2. What two body systems provide these reactants? 3. What are the waste products created by cellular respiration?4. How is this different than photosynthesis?5. What pigment makes plants appear green?

CLASS PLANT PROJECT!!

• LET’S MAKE A PREDICTION:

IF WE COVER SOME OF THE LEAVES OF OUR CLASS PLANT WITH OPAQUE PAPER COVERS, WHAT WILL HAPPEN AFTER A WEEK?!

- Write your prediction on a note card and post it by our class plant!

(… anyone have suggestions for names?)

Photosynthesis

Energy from the Sun is necessary to begin the process.

Besides green plants, some algae and some bacteria can also make their own food.

Radiant energy from the Sun, in the form of light, begins photosynthesis.

Water is taken into the plant by the roots and carried to the leaves through the xylem .

H20H20 H20

Phloem moves sugars from the places where the food is produced to the places where it is needed or stored.

Carbon dioxide (CO2) is taken into the plant through the stomata on the underside of leaves.

Water vapor is released into the atmosphere through the stomata on the leaves.

CONNECT TO PREVIOUS KNOWLEDGE…

WHAT IS THIS PROCESS CALLED?!!?!

Photosynthesis Chemical Equation

Materials: Notes from Today and Last Class!Voices/Movement: “Restaurant voices,” sitting stillInstructions: 1.Write the chemical equation for photosynthesis IN WORDS in the space below.2.Write a sentence describing this chemical process.

Explanation of the Chemical Equation.

Water Molecule: H2O SIX WATER MOLECULES

VENN DIAGRAM

Voices/Movement: “Restaurant,” sitting still

Instructions: Fill out the Venn Diagram on your notes to compare and contrast cellular respiration and photosynthesis!

Success: You should write at least three (3) things in each category!

THE RELATIONSHIP BETWEEN PHOTOSYNTHESIS AND CELLULAR RESPIRATION

Cellular Respiration & Photosynthesis Relationship

Voices/Movement: “Restaurant,” sitting still

Instructions: Describe the relationship between cellular respiration and photosynthesis!Success: You should write at least three (3) complete sentences!

INSIDE OF A PLANT!

PHOTOSYNTHESIS = Water + sunlight + carbon dioxide -> oxygen + glucose

WHAT PROCESS DO WE NEED OXYGEN AND GLUCOSE FOR?!!?!?!?!?!?!?!?!!?!?!?!?!?!?!?!

…… WHAT PROCESS?

CELLULAR RESPIRATION!!!!!!!!

PHOTOSYNTHESIS = Water + sunlight + carbon dioxide -> oxygen + glucose

CELLULAR RESPIRATION = oxygen + glucose -> carbon dioxide + water +

energy!!!!!

CELLULAR RESPIRATION HAPPENS IN BOTH PLANTS AND ANIMALS!!!!!!!!!!!!!

PHOTOSYNTHESIS IS ONLY IN PLANTS!!!!!!

HOW IS THIS CONNECTED TO THE ENERGY PYRAMID???!!?!?

WHEN WE USE ENERGY (ATP), IT IS RELEASED INTO THE ATMOSPHERE IN THE FORM OF WHAT???????

PHOTOSYNTHESIS = Water + sunlight + carbon dioxide -> oxygen + glucose

CELLULAR RESPIRATION = oxygen + glucose -> carbon dioxide + water +

energy!!!!!

WHEN WE USE THIS ENERGY ….IT TURNS INTO HEAT!!!!!!!

SO WHAT PROCESSES ARE HAPPENING HERE?!?!

WHERE DO THESE PROCESSES HAPPEN?

CELLULAR RESPIRATION: IN THE MITOCHONDRIA!!

PHOTOSYNTHESIS:IN THE CHLOROPLASTS!!!

HOW DO CHLOROPLASTS CAPTURE SUNLIGHT?!

WITH A GREEN PIGMENT CALLED ………..

CHLOROPHYLL!!!!!!!

NOW… TODAY… WE ARE GOING TO USE….

THE SINK OF SCIENCE!!!!!!!!!!!!

CHLOROPHYLL EXTRACTION

Voices/Movement: You will use “restaurant voices” to talk to your lab partner. Instructions: Listen to the instructions I am about to explain! They are also written on your LAB SHEETS!!!Success: Finish this lab activity carefully and safely! Answer all the questions thoughtfully before our time is up.

TEXT SUPPORT

Materials: Textbook, pages 231-234.

Voices/Movement: “Restaurant voices” and sitting still.

Instructions: Complete the reflection questions in your notes (answer on a separate piece of paper) as you read the text!
