The document discusses the key processes and functions that are common to living things, including nutrition, transport, respiration, excretion, synthesis, growth, regulation, and reproduction. It explains that living things obtain food, move materials within their bodies, release energy from food through respiration, remove waste, grow, maintain internal balance, and reproduce. Some examples provided are that plants perform photosynthesis and humans breathe out carbon dioxide as part of respiration and excretion.

1. The Processes of Life

2. Life Processes
Biology is the study of life and of living organisms, with
reference to:
Structure
Function
Growth
Evolution
Origin
Reproduction
Behavior
But what makes something living?

3. What makes something living?
1. How are living things different from non-living things?
2. What are some common features of living things?

4. Life Functions
Nutrition - the way an organism obtains its food
Transport - move materials within organism
Respiration - break down and release energy from food
Excretion - removes wastes
Synthesis - creating bigger molecules by joining smaller pieces together
Growth - increase in number of cells or cell size
Regulation - maintain balance or a constant internal environment
Reproduction - produce new individuals

10. Nutrition
The way in which an organism obtains its food
Heterotrophic Autotrophic
Obtains its food Makes its own food

11. Transport
Move materials within organism

12. Respiration
The release of energy from food
ATP

13. Removes wastes
Excretion

14. Synthesis
Building larger molecules by combining smaller
molecules

15. Growth
Increase in cell size or number

16. Regulation
Maintain balance or a constant internal environment

17. Reproduction
Produce new individuals

21. ATP is created by
using oxygen

divides into
two new cells
A fish embryo
divides from 4
cells to 8 cells

22. Metabolism
The sum of all the life functions in an organism
The goal is to maintain homeostasis = stable internal environment

23. Marvin was sent to Earth to find life. In doing
so, he captured a car to bring back to his
planet.
First, explain why Marvin may have thought the
car to be living!
Then, as a human, help Marvin understand
why the car is considered non-living.
Be sure to include Life Functions
