Explain what happens during the
process of photosynthesis.
Explain what happens during the
process of respiration.
Be sure to use the following words in
each of your explanations:


Carbon Dioxide
Oxygen
Glucose
Energy
Water
Photosynthesis

Photosynthesis happens inside of
the chloroplast of plant cells. During
this process plants absorb carbon
dioxide from the atmosphere
through their leaves, water through
their roots, and light energy from
the sun through their leaves. They
combine all of these things to make
their food, glucose. Through this
process, they also produce (give
off) oxygen.
Respiration

Respiration occurs in the
mitochondria of both plant and
animal cells. During respiration
simple sugar (glucose) and oxygen
taken in by the cells are broken
down into carbon dioxide, water,
and energy.
Include the following….


What takes place during the process?
The organelle where the process
takes place
A picture of that organelle
Any formulas associated with that
process
A drawing to represent the process.
Instructions for Foldable



Draw and cut out one Chloroplast
and one Mitochondria.
Glue them under the appropriate
information
Draw & Label an Animal Cell AND a
Plant Cell on the back of your
foldable.
Test Corrections




On a sheet of notebook paper, write the
questions that you missed and their
answers.
For the sheet on Labeling the Cell, draw the
cell over again and label it correctly.
Staple your test corrections to your test
and place them on the front table.
Go back to your seat and complete the
assignment on the board using your
science book. The answers will go in your
notebook.
Writing Prompt

Draw a chloroplast.
What is the function of the
chloroplasts? And are they found in
plant cells, animal cells, or both?
Draw a mitochondria.
What is the function of the
mitochondria? And are they found in

Cellular Processes
What is a cell?

The smallest unit of life capable of
performing life functions.
Cellular Processes
What does a cell have
to do?
Organisms survive because of 4

Respiration
Waste
Mitosis

In the Chloroplasts
Photosynthesis



Plants use light energy
To combine with carbon dioxide
To combine with water
To make simple sugar
So the plant can use it
Extra sugar is stored in the vacuoles
This happens in the chloroplast

Recipe for Photosynthesis





Add 6 molecules of carbon dioxide
Add 6 molecules of water
Add light energy (sunlight) to
change into chemical
energy(chemical reaction)
This makes food – Sugar
6 molecules of Oxygen are released
into the air.
Photosynthesis
Respiration


All organisms (plants and animals)
break down simple sugar into
carbon dioxide and water and
release energy.
Respiration occurs in the
mitochondria of cells.
Why does a cell need energy?

Respiration
Photosynthesis vs. Respiration
Photosynthesis
 Simple sugar made
 CO2 taken in
 O2 given off
 Produces simple sugar
& oxygen
 Takes place in
chloroplasts
Respiration
 Simple sugar broken
down
 CO2 given off
 O2 taken in & used
 Produces carbon
dioxide & water
 Takes place in
mitochondria
Waste Elimination

Organisms rid cells of waste
products that could be harmful
Waste Elimination
As
waste products
accumulate in a cell,
The waste will diffuse
out of the cell.
Diffusion occurs
Mitosis
 Cell
reproduction
 Starts in the nucleus of the
cell
 Produces two daughter cells
 Identical cells produced
 NEEDED for growth,
replacement, and asexual
reproduction.
