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

Section 7-3

Figure 7-15 Osmosis

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?
