Document Summary

All living organisms are composed of one or more cells. Cell theory- the cell is the basic unit of life, of which all living organisms are composed, and living organisms can only be derived from pre-existing living cells. What makes a living organism: cellular organization- all living things are composed of one or more living cells, metabolism- the production and consumption of energy, homeostasis-stable internal condition, growth and reproduction-both sexual and asexual. Can be increase in number of cells, size of cells, or production of new cells/organisms (fission-splitting to form identical copies: heredity- all organisms contain dna, which is the genetic material. It contains the genes that determine how you look and function. Levels of complexity in cells: atoms- fundamental elements of matter, molecules- joining of atoms, macromolecules-larger more complex molecules, organelles- membrane bound structures inside the cell that carry out specific functions for the cell, cells- basic unit of life. Evolution- the gradual change in organisms over time.

Biology, the study of life, is a particularly exciting area ofscience because it is a point of convergence for information andtools from all of the natural sciences. Based on your knowledge ofbiology, indicate whether each of the following statements aboutliving systems is true or false.

1. Cells are composed of chemicals and both the structure andfunction of cells are regulated by the basic principles ofchemistry.

2. Scientists have successfully sequenced the entire genome ofhumans but have not yet sequenced the entire genome of any otherspecies.

3. Living systems are the most complex chemical systems onearth.

4. Living systems are governed by the same principles ofchemistry and physics that govern non-living systems

. 5. Living organisms contain unique chemical elements which arenot found in non-living systems.

6. An input of energy is required to maintain the complexity ofliving systems.

7. The energy conversions that take place in living systems aregoverned by the same laws of thermodynamics that govern non-livingsystems.

Consider a group of humanoids like Geth, an imaginary group of artificial intelligence as seen in video game franchise Mass Effect ( http://masseffect.wikia.com/wiki/Geth) that gained sentience, consist of individually operating physical units that have a compute unit not only acting individually but share a common network for thought processing and decision making. Considering the properties of life as discussed in Campbell Biology Chapter 1, would you consider Geth as living or not? Explain your reasoning via discussing at least 1 aspect/property of life. !!! Properties of life are:

Order. Organisms are highly organized structures that consist of one or more cells. ...

Sensitivity or Response to Stimuli. Organisms respond to diverse stimuli. ...
