1. Exploring and Classifying Life
Chapter 1

2. Characteristics of Life:
Living things are made of cells.
Living things use energy.
Living things grow, develop and adapt.
Living things respond to their environment.
Living things reproduce.

3. All Living Things are Made of Cells!!
Cell – the smallest unit of an organism that carries out the function of life.
Cells ONLY come
from other cells!

4. Living Things use Energy
All of our energy comes from the sun!

5. Living things grow, develop and adapt.
Living things grow in size.
Living things grow in
complexity.
Living things adapt,
or change as they grow.

6. Living Things Respond to their Environment
Stimulus- Signal to which an organism reacts.
Response- an action caused by a stimulus.

7. Living Things Reproduce
Reproduction- the process by which living things give rise to the same kind of living things.

8. Living Things Made of Cells Use Energy Grow, develop and adapt
Reproduce
Respond

9. What do Living Things Need??
Living space
Water
Food

10. Classification
The grouping of things according to similar characteristics.
We put objects into groups based on how similar they are.

11. Taxonomy The science of classification!
Aristotle- an ancient Greek philosopher who classified organisms as plants or animals.

12. Carolus Linnaeus
Swedish naturalist that grouped organisms by similar structure.
He used Binomial Nomenclature- two part naming system.
He identified creatures
by two names:
genus and species.

13. Modern Classification
Modern scientists use:
similarities
fossils
&
genetics to group organisms today.

14. Pneumonic Device King Phillip came over for good spaghetti.
Kingdom, Phylum, Class, Order, Family, Genus, Species.

15. Modern Classification
Kingdoms are the largest and most general category.
While species are the smallest and most specific.
Organisms belonging to the same species can reproduce offspring.

16. Scientific Names
Using common names among scientists can cause confusion.
Linnaeus helped solve this problem by developing binomial nomenclature.

17. Examples of Scientific Names
Acer rubrum=
red maple

18. Homo Sapiens=People

19. Drosophila melanogaster –
Fruit Fly

20. Acer palmatum dissectum atropurpureum –
Purple Cut leaf
Japanese Maple
