1. Packet #2 Anatomy & Physiology Version
Properties of Life
Packet #2
Anatomy & Physiology Version

2. Introduction
All living things are parts of larger systems of matter and energy.
This energy & matter continually recycle through systems as energy flows through the systems.
Knowing this fact, what defines living things (biotic) from non-ling things (abiotic)
Properties of life.

3. Obeying the Lays of Universe
Properties of Life

4. Obey Physical & Chemical Laws of Universe
All living things MUST obey the laws of the universe
Law of Conservation of Mass
Living things are involved in the process of recycling matter or are recycled into a different form of matter
Law of Conservation of Energy
Energy cannot be created or destroyed but changed from one form to the next

5. Order
Properties of Life

6. Order All living things maintain a high degree of order and complexity
Even the smallest living thing—a cell

7. Descendants from Common Ancestor**
Properties of Life

8. Descendants from a Common Ancestor**
All living things are descended from a common ancestor**
Intriguing Questions
Where did life originate?
How did humans originate?
How did life come into existence?
Does having similar physical traits mean that there is a common ancestor?

9. Theories on Origin of Life I
The Creation Theory
A supreme being, God, created the universe and all within

10. Theories on the Origin of Life II
The Theory of Evolution
Chemical evolution
Life arose from an assembly of large molecules
Followed by the historic development of a related group of organisms

11. Theories on the Origin of Life III
Panspermia
Life was formed elsewhere in the universe and was placed on the newly formed planet Earth
Theory that microorganisms or biochemical compounds from outer space , extraterrestrials, are responsible for originating life on Earth and possibly other parts of the universe where suitable atmospheric conditions exist

12. Regulate & Use of Energy
Response to Stimuli
Properties of Life

13. Regulate Use of Energy & Respond to Environment
All life depends on chemical reactions that take place within cells
Within cells and organisms are series of chemical reactions metabolic pathways, sometimes in response to the environment, that are regulated by enzymes.
The production of energy inside cells occur efficiently because of the use of enzymes.
Relate to autotrophs & heterotrophs.

14. Reproduction
Properties of Life

15. Reproduction I All living organisms share same genetic code
Reproduction allows the genetic code to be passed parent to offspring during reproduction.

16. Reproduction II
On the hierarchy of biology, reproduction occurs at two levels
Organism Reproduction
Sexual
Asexual
Cellular {Eukaryotic Cells Only}
Meiosis
Cell Cycle
How does all of this relate to humans?

17. Reproduction III
Humans, within marriage, reproduce sexually (sex) at the organism level.
However, before humans, within marriage, are able to reproduce, reproduction must first occur at the cellular level.
Asexual cellular reproduction
Somatic cells
Sexual cellular reproduction
Sex cells
Sperm
Egg

18. Osmoregulation
Properties of Life

19. Osmoregulation
Maintenance of an optimal, constant osmotic pressure/potential in the body of a living organism.
Deals with water

20. Communication
Properties of Life

21. Communication Intra (within) or inter (between)
Communication not only between different organisms but more importantly within the organism itself
Nerve cells communicating

22. Animation (Movement)
Properties of Life

23. Animation
In regards to living things, movement occurs within humans are various levels of the hierarchy.
Including but not limited to…
Cells
Organism

24. Change Form & Function {Growth & Development}
Properties of Life

25. Change Form & Function Growth & Development
All living organisms change form and function at different stages of their life cycles
Grow
Divide
Develop
Differentiate

26. Death
Properties of Life

27. Death
Death
Absence of previous 9 properties
