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.
2. Key Objectives:Key Objectives:
The student will:
– Investigate and understand
cell structure and organelles
– Describe cell organelles and
their functions
3. Key Objectives:Key Objectives:
The student will:
– Investigate and understand
the basic needs and life
processes of plants
– Identify how plants obtain the
resources they need to
survive
5. Key Objectives:Key Objectives:
The student will:
– Investigate and understand
the physical and chemical
process of cellular respiration
and its importance to plant life
6. Key Objectives:Key Objectives:
The student will:
– Investigate and understand
that photosynthesis is the
foundation of virtually all food
webs
9. Photosynthesis
The life process carried out in
chloroplasts within some plant
cells:
– Energy from light is used to
make food molecules
(Glucose - C6H12O6)
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
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
19. 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
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
Water in
– Stoma
CO2 in, O2 out through the underside of the
leaf. Water Vapor out
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
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)
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
