Today in class we reviewed for Chpt 7 test

Due Thursday:
Chapter Review at the end of Chpt 7: # 12-23, 26-29

Morning review session on Thursday beginning at 7:15

Active Transport

Do Now:
What is water potential?
What two factors influence water potential?

Today in class we:
- Discussed facilitated diffusion, protein-ion pumps, endocytosis, and exocytosis
- Completed lab work and worked on analysis

Due Tuesday:
- Complete all components of osmosis and diffusion lab including graph and analysis

Plasmolysis of Plant Cells

Do Now:
Define Osmosis.
Define the three types of osmotic solutions and describe how water behaves in the presence of each solution.

Today in class we:
Worked on Part 2 of Diffusion and Osmosis Lab, and Part 3 data collection

Diffusion and Osmosis Lab

Do Now:
Define Diffusion
What factors influence whether a solute will diffuse through a cell membrane?

Today in class we:
- Discussed osmosis

• Passive transport
• Hypertonic, hypotonic, and isotonic soultions

- Began work on osmosis and diffusion in living organisms lab

Types of Transport Across Cell Membrane

Do Now: List three components of the cell membrane. Describe the structure and function of each.

Today in class we discussed:
Concentration of solutions
Passive and Active Transport
Diffusion

Homework due Monday
Read section 7.3: Complete Data Analysis on pg 188 and Section Review on pg 189

The Cell Membrane

Today in class we:
Discussed the components of the cell membrane

• Phospholipid bilayer

- Hydrophilic phosphate heads
- Hydrophobic fatty acid tails

• Integral and Peripheral proteins
• Carbohydrate chains

- Fluid mosaic model of cell membranes

Worked on cell membrane model lab

Homework for Thursday:

Quiz corrections

Cell anatomy

Do Now:

1. What is the function of the nuclear envelope?
2. what type of cells contain a cell wall?
3. What are ribosomes and where are they produced?
4. What are the structural and functional differences between Rough and Smooth ER?

Today in class we:
- Discussed the structure and function of the following organelles: (find PPT lecture on the sidebar)

• Golgi Apparatus
• Lysosomes
• Vacuoles
• Mitochondria
• Chloroplast
• Cytoskeleton

- Played Cell Anatomy Memory game (find print out for the cards on the side bar)

Homework:
Read section 7.2 and answer review questions
Study for quiz on sections 7.1 and 7.2
Extra Credit Opportunity - see sidebar for link to assignment

Organelles of the Cell

Do Now:
How has technology influenced what we know about cells and how cells are arranged in organisms? What significance has this had on science and society?

Today in class we:
Discussed the nucleus and its parts: nuclear envelope, nucleolus, and chromatin
Discussed several organelles of the cytoplasm: Ribosomes, Endoplasmic Reticulum
