The document discusses key objectives and terms related to photosynthesis. The objectives are for students to understand cell structure and organelles in plants, the basic needs and life processes of plants, and the physical and chemical processes of photosynthesis and cellular respiration. Key terms defined include photosynthesis, stoma, guard cells, reactants, and products. Diagrams of plant cell structures like chloroplasts, stomata, and mesophyll cells are also included.

9. Photosynthesis
The life process carried out in
chloroplasts within some plant
cells:
– Energy from light is used to
make food molecules
(Glucose - C6H12O6)

10. Photosynthesis

11. Photosynthesis

12. 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

13. Stoma (stomata)

14. Guard Cell(s)
Two small leaf cells on each
side of the stoma that open and
close the stoma

15. Guard Cell(s)
STOMA
OPEN
STOMA
GUARD CELLS

16. Reactant
In a chemical equation these
are the chemicals that begin
the process or what goes in to
the equation
6 CO2 + 6 H2O  C6H12O6 + 6 O2

17. Product
In a chemical equation these
are the chemicals that end the
process or what comes out of
the equation
6 CO2 + 6 H2O  C6H12O6 + 6 O2

18. Chemical Bond
The result of a chemical
reaction when two reactants
combine chemically to form
new products

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

20. Slides for lab activity
What do Plants need for
Photosynthesis?
– Sunlight
– Chlorophyll
– Water H2O
– Carbon Dioxide CO2

21. Slides for lab activity
How do you think plants get the
things for photosynthesis?
– Chloroplasts in Leaves
Absorbs sun light
– Roots

31. Photosynthesis

32. Essential Learnings
Organisms that perform
photosynthesis are called
producers because they make
or produce their own food.
Consumers and Decomposers
make up everything else

33. Essential Learnings
Photosynthesis is
the process in
which producers
make food by
using light
energy, carbon
dioxide and water

34. 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

35. Essential Learnings
Carbon dioxide (CO2) and water
(H2O) are the raw materials
which plants must obtain from
the environment for
photosynthesis

36. 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

37. 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)

38. Essential Learnings
Plants produce sugar called
glucose for food and oxygen as
bi-product during
photosynthesis

39. Essential Learnings
First level/primary Consumers
called Herbivores eat the plants
to get energy from the glucose
stored inside the plant.
– Ex. Insect

40. Essential Learnings
Secondary consumers called
Carnivores eat the Herbivores
– Fish
Third-level or Tertiary consumers
called Omnivores eat everything to
get their energy
– Bear

41. Essential Learnings
Decomposers break down the
waste products and dead
organisms and return the
nutrients to the soil
