Bell ringer What is the first thing that comes to mind when you hear, or see, the word “Marine”?

Was it this???

Or was it this??

The word “Marine”: Refers to; anything of, found in, or produced by the sea.

Marine Biology vs. Oceanography Marine Biology is the study of life in the ocean. Oceanography is the study of the physical characteristics of the ocean Sir Charles Thompson is considered to be the “Father of Oceanography”.

Physical Characteristics of Water Color Temperature Turbidity- cloudiness Salinity- saltiness Pressure Currents Density

The Water Planet Our Earth is made up of 71% water. Most of that water is marine (salt). Less than 10% of the Earth’s water is freshwater. Of that 10% less than 3% is drinkable! What is the other 7%?

Let’s go to the Video!

End INVESTIGATION! When Ms.Lau says go: I will have three minutes to put the pictures of various organisms into three groups based on how similar YOU think they are! I will work with my team to get the most similar organisms in a group! 3 minutes End

Why is it important to classify the information that we know about these organisms?

There are 8.7 million different species on this Earth. ……..that we KNOW of!!!!

Organisms have been evolving for millions of years. There are about 5-10 million species of organisms. So, how do we go about organizing all of these organisms?

Carolus Linnaeus (1707-1778) Created Taxonomy Taxonomy: system by which organisms are classified Why do you think there are more species today? Why is having a single system to classify organisms important?

Taxonomy: system by which organisms are classified

Naming System A Hierarchical system. Domain - (broadest area) Kingdom Phylum Class Order Family Genus Species – (most specific area) Every organism is grouped in each of these categories.

Let's Memorize It! Dear King Phillip Came Over For Grape Soda Domain Kingdom Phylum Class Order Family Genus Species

Which level is the most broad? Explain

How are organisms named? Binomial Nomenclature= the way organisms are named First Word=Genus Second Word=Species EX: The Panthera tigris walks on 4 legs and is heterotrophic. THE POINT OF THIS SLIDE. Let students know that if they see this long latin word on the test that it means nothing then it being an organism. They just need to figure out how it is classified.

We are only focusing on…….. Domain Kingdom Phylum Class Order Family Genus Species

Domains There are three Domains that all living things are classified under.

The Domains are then divided into _______ kingdoms Archaea Archaebacteria Bacteria Eubacteria Eukarya Protista, Fungi, Plantae, Animalia

Eukarya Eubacteria and Archaebacteria

Archaebacteria Unicellular Asexual Reproduction Autotrophic Oldest known living organism Live in extreme conditions (hot, freezing, salty, anaerobic)

Bacteria Unicellular Asexual Reproduction Autotrophic with Cell Walls Peptidogylcan Live in a variety of environments. Examples: Salmonella, E. Coli

Peptidoglycan, also known as murein, is a polymer consisting of sugars and amino acids that forms a mesh-like layer outside the plasma membrane of most bacteria, forming the cell wall.

There are two type of Bacteria

Eukarya Unicellular or Multicellular Asexual and/or Sexual Autotrophic or Heterotrophic Their genetic material is made of DNA, which causes them to be the most diverse domain!

Eukarya is Divided into 4 Kingdoms K=FAPP 4 Kingdoms Fungi Animalia Plantae Protista hydrophytes

K=FAPP: Fungi Multicellular Both Asexual or Sexual Absorptive Heterotrophs Chitin Examples: Mushrooms, Yeast, Mold

K=FAPP: Animalia Multicellular Ingestive Heterotrophs Examples: Homo Sapiens, Cheetahs, Birds

K=FAPP Plantae Multicellular Autotrophic Cellulose Through what process? Photosynthesis! Cellulose Examples: Spruce Trees, Grass, Sunflowers

K=FAPP Protista Most are unicellular and some multicellular Like Plants (cellulose), Like Animals (no cell walls) Some heterotrophic and some autotrophic Examples: Algae Protozoa

Show Me What You Got! These organisms have membrane-bound organelles. 1= Archaebacteria 2= Bacteria 3= Eukarya These organisms have membrane-bound organelles. These organisms are considered the oldest organisms alive These organisms have cell walls made of peptidoglycan These organisms can be unicellular or multicellular

Show Me What You Got! These organisms conduct photosynthesis! 1= Fungi 3= Plantae 2= Animalia 4= Protists These organisms conduct photosynthesis! I am a Eukaryote that is unicellular, mobile, and an autotroph. What am I? I am a decomposer that has cell walls made of Chitin. These organisms can be unicellular or multicellular

Guess Who? Oh NOOOOOO! There has been a kidnapping! Dory has been captured and taken from her Family! We must figure out the perpetrator! Figure out what Domain and Kingdom the perpetrator is in! There are 6 clues around the room You will have 12 minutes to travel around the room to try to answer as many of the clues as possible
