1/29/07 Transcription of Dr. Wayne’s Lecture The Cell is the Basic Unit of Life Study Hint : Be able to identify the parts of the cell & know the function(s) of these parts [see notes & text to help]. [Clicker question] I presented a physico-chemical scenario for the origin of life. How plausible is it to you that it took place without any need for a Creator? A) Very plausible. I know that the universe started as a fluctuation and then followed the necessary laws of chemistry and physics. B) I am not sure, but leaning toward 1. C) Sometimes I think it is plausible, other times I think it is unlikely. D) I am not sure, but leaning toward 5. E) Very unlikely. I know that such a scenario is impossible without a Creator. Any of the above answers were accepted as correct. Randy said he would have chose C —“well maybe” The science behind the origin of life concept is that an enormous amount of energy is needed to create life….. makes you think! Another unifying concept behind the introduction to the origin of life lecture is Energy. You’ll observe that we spend a lot of time talking about energy, energy transfer and energy storage during the upcoming lectures. Remember that energy is key to allowing living things to maintain & carry out the characteristics of life. Last lecture covered : Physico-chemical origin of life Today’s lecture will cover : Cells are living things that are vibrant & move The cell as the basic unit of life o cells as the smallest entity with all the characteristics of life o Structure & function of cells and their ‘parts’ (ppt) A Cell is the Basic (Physico-Chemical and Biological) Unit of Life Cells are the basic units of life and all the chemical reactions of life occur in cells (ppt) Golden Age of Biology Numerous economic opportunities found in biology (ppt Series: quotes from The Declaration of Independence ) Laws of Nature & of Nature’s God. o On July 4, 1776, the thirteen colonies of the United States unanimously declared……….

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
