Photosynthesis
Slide 3
What Happens during Photosynthesis?
Slide 4
1.Chlorophyll traps light causing Water to split into H and O H
2 O H 2 + O
Slide 5
2. Oxygen (waste) exits through stomata Hydrogen = used for
next part H 2 O H 2 + O Oxygen (air)
Slide 6
3.CO 2 and H combine to form glucose CO 2 + H Glucose (C 6 H 12
O 6 )
Slide 7
Chemical reaction Sunlight + Carbon dioxide + Water Glucose +
Oxygen (Raw materials/reactants) (products) SUNLIGHT + H 2 0 + CO 2
C 6 H 12 O 6 + O 2 Sunlight = provides the energy needed to begin
the process of photosynthesis Reactants/ Raw materials = the
chemicals needed to start process Products = the substances made
from the process. Sunlight + Carbon dioxide + Water Glucose +
Oxygen (Raw materials/reactants) (products) SUNLIGHT + H 2 0 + CO 2
C 6 H 12 O 6 + O 2 Sunlight = provides the energy needed to begin
the process of photosynthesis Reactants/ Raw materials = the
chemicals needed to start process Products = the substances made
from the process.
Slide 8
Carbon + dioxide wateroxygenglucose + light enzymes light 6CO 2
+ 6H 2 O C 6 H 12 O 6 + 6O 2 enzymes
http://www.kscience.co.uk/animations/photosynthesis.swf (waste) The
formula of photosynthesis
Slide 9
Define Photosynthesis. What is the energy source that starts
the process? THE SUN
Slide 10
What raw materials are used by the process of photosynthesis?
and Carbon Dioxide Water
Slide 11
What are the products of the photosynthesis ? Glucose (Sugar)
O2O2
Slide 12
Where does Photosynthesis occur?
Slide 13
The Leaf is the plants photosynthetic organ. The leafs
chlorophyll absorbs solar energy. This is where photosynthesis
occurs.
Slide 14
CHLOROPLASTCHLOROPLAST SITE OF PHOTOSYNTHESIS
Slide 15
The inside of the leaf: The leaf is made up of many cells which
contain organelles called chloroplasts. * See Leaf structure
handout
Slide 16
Why Is the Sunlight important?
Slide 17
Sunlight or White light Sunlight or white light is actually a
combination of all the colors of the rainbow: Blue, indigo, violet,
green, yellow, orange, and red. Plants appear green because they
absorb all the colors except green, which is reflected. It is the
energy from light that energizes electrons which start the process
of photosynthesis.
Slide 18
Photosynthetic pigments: Which colors are most effective for
photosynthesis?
Slide 19
Best color light for photosynthesis Blue & red Easily
absorbed
Slide 20
Different wavelengths of visible light are seen by the human
eye as different colors. WHY ARE PLANTS GREEN? Gamma rays X-rays UV
Infrared Micro- waves Radio waves Visible light Wavelength
(nm)
Slide 21
Sunlight minus absorbed wavelengths or colors equals the
apparent color of an object. The feathers of male cardinals are
loaded with carotenoid pigments. These pigments absorb some
wavelengths of light and reflect others. Reflected light
Slide 22
Why are plants green? Reflected light Transmitted light
Slide 23
Chloroplasts contain PIGMENTS (chlorophyll) that absorb the
suns energy and use it to create glucose Light THE COLOR YOU SEE IS
THE COLOR REFLECTED
Slide 24
Least effective = GREEN (reflected)
Slide 25
Define Photosynthesis It is the process that plants use to
create food (organic materials) using the suns energy.
Slide 26
Review:Review: What is the equation for photosynthesis?
SUNLIGHT + H 2 0 + CO 2 C 6 H 12 O 6 + O 2
Slide 27
What are the best color lights for photosynthesis to occur?
Blue & red Because they are easily absorbed Review:Review:

Aim: How are plants adapted for autotrophic nutrition? Do Now:
1.) 2.) Identify A and B B A
Slide 30
ROOTS STOMATA LEAVES VASCULAR TISSUE/BUNDLE
Slide 31
the root is the organ of a plant body that typically lies below
the surface of the soil The two major functions of roots are ROOTS
1.) absorption of water and inorganic nutrients 2.) anchoring the
plant body to the ground
Slide 32
STOMATA (stomate; singular) is a pore found in the leaf and
stem epidermis that is used for gas exchange Guard cells Guard
cells are responsible for regulating the size of this opening
Slide 33
Guard cells and Homeostasis Guard cells control the opening and
closing of the stomata. This allows the leaf to control water loss
(transpiration). They allow carbon dioxide to enter and oxygen to
be released. Guard Cell Stomata
Slide 34
is the evaporation of water from plants that occurs at the
leaves while their stomata are open (for the passage of CO2 and O2
during photosynthesis)stomata Transpiration
Slide 35
Why are most plants green? The leaf and chloroplasts The
organelle chloroplast contains the pigment chlorophyll which
absorbs every color except green which is reflected. How does
chloroplast assist in autotrophic nutrition?
Slide 36
The planet is 70% water so most photosynthesis occurs in the
oceans. On land or under water, the process of photosynthesis is
still the same: energy + carbon dioxide produces sugar and oxygen.
The producers are algae and phytoplankton. On land or under water,
the process of photosynthesis is still the same: energy + carbon
dioxide produces sugar and oxygen. The producers are algae and
phytoplankton.
Slide 37
Phytoplankton: producers in the oceans Located just beneath the
waters surface These producers form the foundation for marine food
webs
Slide 38
What role does chloroplast and chlorophyll play in the process?
Chloroplast is the organelle inside the plant cell that
photosynthesis takes place. Chlorophyll is the pigment that
attracts light to start the process.
Slide 39
What is the least effective light for photosynthesis? GREEN
because most plants reflect the color!
Slide 40
What is the photosynthetic organ of the plant? The LEAF
Slide 41
How does carbon dioxide enter the plant? Carbon dioxide enters
the leaf through openings called stomata Stoma
Slide 42
Photosynthesis review: What part of the leaf regulates
transpiration and gas exchange? Guard Cells Review
Slide 43
ReviewReview Guard cells control opening of stomata. Carbon
dioxide enters the leaf through openings called stomata. Water is
absorbed from the soil and is carried to the leaf.
Stomata=pores
