Unit 2 Review Guide
-
Organelles – matching section
- Word list with definitions below
- Transport – know difference between passive and active transport --- Know examples of each
- Know these terms: hydrophilic; hydrophobic; semi-permeable/selectively permeable; hypotonic; hypertonic; isotonic
-
Mitosis
- Be able to determine the different phases by looking at diagrams
- Determine which phase is being described
- Short Answer – Problem solving:
- Example
A cell that is 9% glucose and 15% albumin is suspended in a solution that is 12% glucose and 8% albumin. All substances mentioned are permeable through the cell membrane and pass through by passive transport. Using the choices: (A) Enters the cell, (B) Leaves the cell, or (C) Does Not Move, please tell how each of the following will move in this solution.
{You may want to draw out a picture to help you solve this problem}
- Glucose _____________________________________
- Albumin ____________________________________
- Water _______________________________________
- Is this solution hypertonic, hypotonic or isotonic? _____________________________ (hint: what is the water doing?)
6. Know reasons why a cell divides
7. Know major elements that make up living things (CHO, CHO, CHONS)
