Objective: You will be able to give the
function of each cell organelle.
Do Now:
• Read, “Nucleus” on p. 176
• What is chromatin made of?
Objective: You will be able to describe
the functions of cell organelles.
Do Now:
• Read the sections on the mitochondria and
chloroplasts on p. 179 and 180
• Write down their functions as it appears in the
textbook
Write this statement down
The mitochondria is a site to see
It has lots of energy
Group Roles
• Leader: Keeps group on task
• Recorder: Keeps a written record of groups work
• Reporter: Presents group’s work to class
• Noise monitor: Keeps groups voices
manageable
Group Work
• Your group will create a rap verse for each
cell organelle
• Start by writing down the organelle’s name
and function
– Try to find words that rhyme with the name or
function
• The best raps will be sent to Snoopy dog to
be put on his next album
Objective: You will be able to
differentiate between plant and animal cells.
Do Now:
• View the Diagram of the cells on p. 175
• What structures do plant cells have that animal
cells don’t have?

Differences Between Animal and
Plant Cells
• Animal cells are round and plant cells are
rectangular
• Animal cells have lysosomes and centrioles
• Animal cells have small vacuoles and plant
cells have one large vacuole
• Plant cells have chloroplasts and a cell wall

Objective: You will be able to describe
the structure of the cell membrane.
Do Now:
• Read “Cell Membrane” on p. 182
• What is the function of the carbohydrates on
the cell membrane?

Paired Work
• You and a partner will build your own
cell membrane
• Use 5 straw pieces, marshmallows,
toothpicks and your textbook
• Build the membrane on computer paper
• You MUST name and give the
FUNCTION each part
Objective: You will be able to define
diffusion and osmosis.
Do Now:
• Read “Diffusion” on p. 184
• Define equilibrium
Figure 8.10 The diffusion of solutes across membranes
Figure 8.11 Osmosis
Figure 7-15 Osmosis
Section 7-3
Is this osmosis?
Objective: You will be able to differentiate
between passive and active transport.
Do Now:
Read “Active Transport” on p. 188
How is active transport different than
diffusion?
