Transcript
1. Go to www.cellsalive.com/ecoli.htm 2. Click on Cell biology; click cell models 3. What are the 2 types of cells? Write a statement that distinguishes the 2 from each other. 4. Click Animal cell, click nucleus A. Describe the nucleus. B. What happens to the DNA in the nucleus when the cell is dividing? C. What structure is also found in the nucleus, and what is its function? Go to http://micro.magnet.fsu.edu/cells/mitochondria/mitochondria.html Write a sentence that specifically describes the function of mitochondria What does ATP stand for? What is its role in cells? How much more energy is obtained through aerobic versus anaerobic respiration? What does this mean for the evolution of complex animals? How large are mitochondria? (um’s) Go to http://library.thinkquest.org/C004535/cell_membranes.html Describe the molecular makeup of a lipid What do hydrophobic and hydrophyllic mean? (may have to search elsewhere) Go back to cellsalive.com click cell cycle Define the cell cycle: Click mitosis List the stages of mitosis beginning with interphase. Discuss 3 events that are unique and occur in each of these phases. INTERPHASE 1. 2. 3. PROPHASE 1. 2. 3. PROMETAPHASE 1. 2. 3. METAPHASE 1. 2. 3. ANAPHASE 1. 2. 3. TELOPHASE 1. 2. 3. CYTOKINESIS 1. 2. 3. http://www.bio.unc.edu/faculty/salmon/lab/mitosis/mitosislinks.html 5. Go to www.libertyzone.com/hz-aging.html and www.e-geriatric.net/theories.html www.prolongyouth.com/theories.html Discuss 2 of the theories or ideas given about the topic of aging, what happens to make cells age and how people could slow the process down
