Wake-up
1. A plant is an autotroph. What does this
mean? (HINT: Animals are heterotrophs)
1. What organelles are found in a plant, but
not an animal?
Photosynthesis
Photosynthesis I
Photosynthesis Function
To produce
glucose
(food) for
producers
The formula
for glucose:
C6H12O6
Photosynthesis: How?
Plants absorb sunlight energy, carbon
dioxide and water to make glucose
Organisms that Undergo Photosynthesis:
Plants
Bacteria
Protists – ex/ Green Algae
Photosynthesis: Location
Chloroplast
Chlorophyll: Pigment
Producer
Leaf
Leaf Cross-section
Structure: Chloroplast
Thylakoid:
Groupinside
of pigments;
Stroma:
Fluid
Grana: Stack of Thylakoids
absorb
sunlight energy
the
chloroplast

2. What is photosynthesis?
3. What is needed for
photosynthesis?
Pigments
Found inside
the thylakoid
Absorb sunlight
energy and give
plants their
color.
Types of Pigments: Chlorophyll a
Bright Green
Types of Pigments: Chlorophyll b
