1. Characteristics of living things

2. The 8 Characteristics of Life
All Living Things…
are made up of cells
(one cell = unicellular / many cells = multicellular)
reproduce
(on their own = asexual / with another parent = sexual)
have a genetic code (DNA) with instructions for growing
and reproducing
grow and develop
use energy and materials
respond to their environment
control the conditions inside their bodies (maintain homeostasis)
Groups of living things adapt/evolve/change over time.
Objectives for Class:
List 6 of 8 characteristics that all living things share

3. Two Main Cell Types (eu = true; karyote = kernel/nucleus)
Eukaryotic
(eu = true; karyote = kernel/nucleus)
Cells that have a nucleus in which their DNA/ chromosomes are stored
Cells that are larger and more complex
Prokaryotic
(pro = before; karyote = kernel/nucleus)
Cells that don’t have a nucleus (DNA just floats around in the cell)
Cells that are smaller and simpler
Class Objective:
Distinguish between Prokaryotic and Eukaryotic Cells

4. Two main cell types: PROKARYOTES and EUKARYOTES
Epithelial Cells w/
Bacilli (bacteria)
White Blood Cell w/
Cocci (bacteria)
Class Objective:
Distinguish between Prokaryotic and Eukaryotic Cells

5. Two main cell types: PROKARYOTES and EUKARYOTES
Class Objective:
Distinguish between Prokaryotic and Eukaryotic Cells

6. Domains & kingdoms of life

7. Domain Bacteria unicellular/microscopic
prokaryotic (tiny cells with no nucleus)
very diverse – live and eat in many different ways
Objectives for Class:
Identify and explain two defining characteristics of each kingdom and domain.

8. Domain Archaea unicellular/microscopic Prokaryotic (no nucleus)
live in extreme environments (very hot, salty, or acidic places)
Objectives for Class:
Identify and explain two defining characteristics of each kingdom and domain.

9. Domain Eukarya unicellular OR multicellular all have nucleus
eukaryotic (bigger cells w/ nucleus and organelles)
includes 4 Kingdoms:
Protista, Fungi, Plantae, Animalia
Objectives for Class:
Identify and explain two defining characteristics of each kingdom and domain.

10. Kingdom Protista all are eukaryotic; most are unicellular
most live in water
“miscellaneous” category – some are like plant cells, some are like animal cells
Objectives for Class:
Identify and explain two defining characteristics of each kingdom and domain.

11. Kingdom Fungi mostly multicellular
decomposers (feed on dead/decaying things)
ex: mushrooms, mold, yeast
Objectives for Class:
Identify and explain two defining characteristics of each kingdom and domain.

12. Kingdom Plantae multicellular
use photosynthesis to make food from sunlight, CO2, and water
Objectives for Class:
Identify and explain two defining characteristics of each kingdom and domain.

13. Kingdom Animalia multicellular eat other living things for food
most can move
Objectives for Class:
Identify and explain two defining characteristics of each kingdom and domain.

14. Biological classification system

15. Classification System: Domain Kingdom Phylum Class Order Family Genus
Hierarchical
Classification System:
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
DOMAIN
Eukarya
Largest category
Smallest & most specific category

16. Species Definition and Examples
Species – a specific group of living things that have similar characteristics, similar DNA, and can reproduce with each other to make fertile offspring (this means their babies can also have babies)
Example: tiger + tiger = baby tiger (which grows up to reproduce)
lion + tiger = liger (a hybrid which can’t reproduce)
Every species has a 2-part Latin name: Genus species
Ex: Canis lupus (wolf)
