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?

Plant Cell Nuclear envelope Ribosome (attached) Ribosome (free) Smooth endoplasmic reticulum Nucleus Rough endoplasmic reticulum Nucleolus Golgi apparatus Mitochondrion Cell wall Cell Membrane Chloroplast Vacuole Section 7-2 Figure 7-5 Plant and Animal Cells

Animal Cell Centrioles Nucleolus Nucleus Nuclear envelope Rough endoplasmic reticulum Golgi apparatus Smooth endoplasmic reticulum Mitochondrion Cell Membrane Ribosome (free) Ribosome (attached) Section 7-2 Figure 7-5 Plant and Animal Cells

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?

Outside of cell Inside of cell (cytoplasm) Cell membrane Proteins Protein channel Lipid bilayer Carbohydrate chains Section 7-3 Figure 7-12 The Structure of the Cell Membrane

Fluid-Mosaic Model Describes the structure of the membrane Lipid Bilayer Proteins used for: –Transporting materials –Receptors Contains carbohydrates

Receptor

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?
