Comparison of active and passive tranpsort

Introduction of Active Transport

Essential Question:  Give 3 examples of diffusion in everyday life.  Sketch one o these examples and show the high and low concentrations and movement of the molecules.

Today we were introduced to the second form of cell transport, active transport.

We will use a worksheet to frame your work today in the reading on passive and active transport.
Click here to access the document.

Active transport is when energy is needed to be used to move molecules from low concentration to high concentration across a cell membrane.  Often in this form of transport, transport proteins are used to aid the process.

Here is an image of active transport.




Here is a video showing active transport in terms of the sodium/ potassium pump.

Cell Transport Introduction. -


Today we will be starting a Unit on Cell Transport (active and passive).

Essential Question - How do the necessary materials get in and out of your cells.

Here are the notes from today's class.  Click here to access.
Today in class we will add to these notes filling in examples of each of the vocabulary terms from demonstrations performed in class.





Here are some interactive links showing diffusion of molecules - a form of passive transport.

Meiosis vs. Mitosis

When you are done your DNA models, check them with a teacher and then start work on the Mitosis vs Meiosis 
Webquest below.
Mitosis and Meiosis Comparison Worksheet

After you have completed the webquest view a few of the below videos.  Pay close attention to the following:
1. How many daughter cells are found at the end of each cell division?
2. What is the function of each division and which cells do they occur in?
3. How many chromosomes are found in the daughter cells compared to the mother cells?
4. How many divisions and interphases does each go through?
