Week 5 - Cell Cycle and Cell Reproduction

Howdy Biologists!  This week we will be looking at the Cell Cycle and Cell Division (Mitosis and Meiosis).

Assignments for Week 5:
Assignment #7 - Mitosis
Identify and describe the stages of mitosis.  The description should contain specific events that occur that are associated with that stage - a key indicator for each stage.  Please submit your homework NLT 8 July 16:30.  Please put your Name and assignment number in the subject line of your email.

Assignment 38 - Meiosis
Define the terms diploid and haploid.  Consider a single diploid cell.  If it undergoes mitosis, how many cells are formed and are they diploid or haploid?  If that same diploid cell undergoes meiosis, how many cells are formed and are they diploid or haploid?  Please submit your homework NLT 8 July 16:30.  Please put your Name and assignment number in the subject line of your email.

Cell division is the only path to immortality. Nondividing cells can live for as long as a hundred years, but they always eventually die.  - Shcleiden & Schwann

Questions from last week's session:  
1.  Infrared heaters work in the 780 nm to 1 mm wavelength.
2.  Carotenemia can be caused by eating lots of carrots.  They have beta-carotene.  Though it can be metabolized by the liver, The excess is deposited in lipids, like the skin of the palms and feet.
