Transcript Objective: You will be able to list the parts of the cell theory.

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?

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
1. Decide and record roles on index card
2. Decide on type of cell structure to create
3. Record each cell organelle and describe
how it is being used in the cell structure
4. Draw a picture that represents your cell
structure
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

Is this osmosis?
