In the assignment you had that was due Tuesday, March 29, you probably found the reading in the green book somewhat confusing. As you can see from the outline I made, it appears that all of those properties under “1) Life has characteristic properties”, are the properties the book uses to define life. However if you read carefully you find that these are characteristics of some living things, but since they are not necessarily the characteristics of all living things, they do not define life. Life is defined later. In my outline, you see it defined under, “2) So what are properties that all living things have? “
Keep in mind that this is an outline of the green book’s material, not my own.
The second outline you were to do (or Cornell notes) was of pages 6-10 in the blue text book. You can see that further below.
Then you were to compare the lists. We did that in class, and found that they are very similar.
Outline of green biology book p 25-27
1) Life has characteristic properties “properties that define if something is a living organism or not”.
(a) animals move about
(b) but trees don’t even though alive
(c) also clouds move but not alive
ii) Sensibility (stimulus-response)
(a) deer flee if hear sound
(b) plants grow towards light
(c) kick a dog and it runs or bites
(d) kick a tree—no response
(a) seeds develop into plants
(b) babies develop into adults
(c) bacteria don’t really develop—they just grow bigger then split
(d) rocks develop over time—but not alive
(a) all living things are complex
(b) so are computers and TV’s
(a) is simply end to life
(b) if can’t identify life, death has no meaning
2) So what are properties that all living things have?
i) cellular organization
(a) all living things are made of cells
(a) physical/chemical changes in organisms that release or use energy
(b) all living things use energy
(a) all living things reproduce
(a) tendancy to maintain stability in organism in midst of environment that is changing
(a) all living things contain genetic information.
Outline of the blue text book pages 6-10
1) Blue Book’s list
Non living things may have some of these characteristics, but living things have them all
i) living things are organized
(a) composed of cells
(b) have DNA
ii) living things make more living things—reproduce
iii) living things change during their lives,
(a) they grow and develop
iv) living things adjust to their surroundings or environment
(a) stimulus – response for conditions requiring it
v) living things adapt and evolve
(b) evolution—accumulation of adaptations
