CELL RESPIRATION & PHOTOSYTHESIS
– ESSENTIAL VOCAB1. Cellular Respiration
A process when gluclose and sugar makes ATP energy
2. ATP
ATP is the energy that is used organisms use to function.
3. Mitochondria
an organelle found in most organisms where respiration and energy
is made.
4. Glucose/C6H12O6
A type of sugar that is made by plants that is used as food
5. Autotroph
An organism that makes their own food and energy
6. Heterotroph
An organism that has to eat other organisms to get energy
7. Aerobic Respiration
8. Anaerobic Respiration
Respiration involving the use of Oxygen to break
down glucose and convert it to ATP, 36 ATP
Respiration not involving the use of Oxygen to break
down glucose and convert it to ATP, 2ATP
9. Photosynthesis
When plants go through an cycle that make carbon dioxide,sunlight,
and water into food to make energy.
10. Chloroplast
The cell that holds the clorphyll
11. Chlorophyll
It is the pigment that makes plants green and it catches sunligh so
the plant can make more food.
12. Carbon Sink
A place where carbon is stored like in a tree
15. Decomposition
when a dead organism is being broken down
16. Homeostasis
The maintaining of a cells/organisms constant internal
environment to sustain life
17. Oxygen/Carbon Cycle The cycling of gases that exist between the processes
of cellular respiration and photosynthesis

Essential Questions:
1. Why do organisms
need a supply of
energy?
Cell Respiration & Photosynthesis
All living organisms must be able to
obtain energy from the environment
in which they live.
Review Autotroph vs. Heterotroph
So they can
reproduce and
function right.
2. Relate
mitochondria in the
cells to cellular
respiration and ATP.
The mitochondria is
where cellular
respiration takes
place then making
atp.

Autotroph

Heterotroph
Autotrophs are organisms that
can make their own food to get
energy. Heterotrophs are
organisms that need to eat
other organisms to get energy.
What is cellular
respiration?
A process that happens in
the cells to make atp.
Where in the cells of
organisms does it occur?
When does it occur?
3. Describe the
importance, process,
and location in the
cell of cellular
respiration.
It takes place in the
mitocondria and it happens
all the time
What types of organisms carry
out cellular respiration?
Why?
Mostly all organisms
Cellur respiration is
because we need to eat
required to make food
things to get our energy.
for most organisms. It
happens in the
mitocondria. It uses Give examples of cell processes that require
gluclose and sugar to
energy:

Essential Questions:
1. Compare and
contrast aerobic vs.
anaerobic
respiration.
Aerobic respiration
uses oxygen,
anaerobic
doesn't.Aerobic yeild
lot of ATP, while
anaerobic only yeild 2
molecules.
Two types of cellular respiration

Aerobic uses oxygen and yields
many more ATP molecules

Anaerobic (aka Fermentation)
doesn't use oxygen and
yields only two ATP
molecules
Essential Questions:
1. Write the equation
for photosynthesis.
6CO2+6H2O—>
C6H12O6 + 6O2
Trapping Energy from Sunlight

Photosynthesis
A process when carbon
dioxide,water,and sunlight
are combined to make
energy for the plant.
The organelle
where
photosynthesis occurs
It occurs in the cloroplast
2. Describe
importance, process,
Types of organisms
and location in the cell
photosynthesis occurs in
of photosynthesis.
Plants and some bacteria
Photosythesis is
important because
the plants give off air The role of chlorophyll in
which lets us
photosynthesis
breath.The plant
Chlorophyll takes in sunlight
takes in sun light,
carbon dioxide, and
water to make food
for itself and gives off
air.

Essential Questions:
1. Compare and
Contrast
Photosynthesis with
cellular respiration.
Photosythesis makes
oxegen.Respiration
make carbon
dioxide.Photosythesis
happens in
plants.Respiration
happens in animals.
2. Describe factors
affecting
photosynthesis.
-Amount of carbon
dioxide
-Tempature
-Amount of light
Factors affecting rates of photosynthesis:

Temperature
As temperature increases, the rate of
photosynthesis increases, but only until an
optimal point and then it decreases.

Light Intensity
As light intensity increases, the rate of
photosynthesis increases, but only until a
point and then remains constant.

Carbon Concentration
As carbon dioxide level increases, the
rate of photosynthesis increases, but
only until a point and then remains
constant.

Essential Questions:
1. Explain the role of
respiration and
photosynthesis in the
Carbon and Oxygen
cycle.
Respiration creates
carbon dioxide so
photosythesis can
take the carbon
dioxide and make it
into oxygen and the
process restarts.
Cellular Respiration & Photosynthesis
complete the CO2 and O cycle

Respiration
When energy is being made when
oxygen is taken in and carbon
dioxide is realese

Photosynthesis
When carbon dioxide is made in to
oxegen and the oxygen is realesed
so animals can breath it in
