Photosynthesis
The life process carried out in chloroplasts within some plant cells:– Energy from light is used to
make food molecules (Glucose - C6H12O6)
Photosynthesis
Photosynthesis
Stoma (stomata-plural)
Openings in the underside epidermis of a green leaf that allow for Carbon Dioxide (CO2), Oxygen(O2) and water vapor to enter and exit the leaf
Stoma (stomata)
Guard Cell(s)
Two small leaf cells on each side of the stoma that open and close the stoma

STOMAOPEN
STOMAGUARD CELLS
Reactant
In a chemical equation these are the chemicals that begin the process or what goes in to the equation6 CO2 + 6 H2O C6H12O6 + 6 O2
Product
In a chemical equation these are the chemicals that end the process or what comes out of the equation6 CO2 + 6 H2O C6H12O6 + 6 O2
Chemical Bond
The result of a chemical reaction when two reactants combine chemically to form new products
Lab TimeLab Time
Now it is time to introduce the new lab.
Pease open your Green lab guides to page 65
Read the introduction silently as I read it aloud
Slides for lab activity
What do Plants need for Photosynthesis?– Sunlight– Chlorophyll– Water H2O
– Carbon Dioxide CO2
Slides for lab activity
How do you think plants get the things for photosynthesis?– Chloroplasts in Leaves
Absorbs sun light– Roots
Water in– Stoma
CO2 in, O2 out through the underside of the leaf. Water Vapor out

Photosynthesis
Essential Learnings
Organisms that perform photosynthesis are called producers because they make or produce their own food.
Consumers and Decomposers make up everything else
Essential Learnings
Photosynthesis is the process in which producers make food by using light energy, carbon dioxide and water
Essential Learnings
Chlorophyll is a green colored chemical inside chloroplasts that allows for the process of photosynthesis to take place
Chloroplasts must be present in the producer to perform photosynthesis
Essential Learnings
Carbon dioxide (CO2) and water (H2O) are the raw materials which plants must obtain from the environment for photosynthesis
Essential Learnings
To obtain materials needed for photosynthesis, plants have roots and stems to absorb water, leaves containing chloroplasts to collect light and stomata on the underside of each leaf to allow for the exchange of gases
Essential Learnings
The stomata located on the underside of the leaf’s epidermis is controlled by guard cells which open and close each stoma to allow for the exchange of carbon dioxide (in) and oxygen and water vapor (out)
Essential Learnings
Plants produce sugar called glucose for food and oxygen as bi-product during photosynthesis
Essential Learnings
First level/primary Consumers called Herbivores eat the plants to get energy from the glucose stored inside the plant.– Ex. Insect
Essential Learnings
Secondary consumers called Carnivores eat the Herbivores– Fish
Third-level or Tertiary consumers called Omnivores eat everything to get their energy– Bear
Essential Learnings
Decomposers break down the waste products and dead organisms and return the nutrients to the soil
