4 Theories of Life Spontaneous Generation – Life came from non-living sources. Spontaneous Generation – Life came from non-living sources. Biogenesis – Life comes from life. Biogenesis – Life comes from life.

5 Life A living part of the natural environment is called a biotic factor. A living part of the natural environment is called a biotic factor. A non-living, or once living, part of the environment is called an abiotic factor. A non-living, or once living, part of the environment is called an abiotic factor.

6 Theories of Adaptation An adaptation is a change in a species over a long period of time. An adaptation is a change in a species over a long period of time. Two scientists have contributed ideas about adaptations. Two scientists have contributed ideas about adaptations.

7 Theories of Adaptation Sir Charles Darwin developed a theory called natural selection. We know his theory as survival of the fittest. Sir Charles Darwin developed a theory called natural selection.

17 2 Types of Bacteria Most scientists have now split Kingdom Monera into two Kingdoms. Those are Kingdom Archaebacteria and Kingdom Eubacteria. Most scientists have now split Kingdom Monera into two Kingdoms. Those are Kingdom Archaebacteria and Kingdom Eubacteria. Kingdom Eubacteria is a general type of bacteria that you would find in your everyday environments from countertops, to soil, to even your skin and body. Kingdom Eubacteria is a general type of bacteria that you would find in your everyday environments from countertops, to soil, to even your skin and body. Examples of Eubacteria are: Esherischia coli, Bacillus pneumonia, Clostridium tetani, and Clostridium botulinum. Examples of Eubacteria are: Esherischia coli, Bacillus pneumonia, Clostridium tetani, and Clostridium botulinum.

18 2 Types of Bacteria The second type of bacteria is known as archaebacteria. Archaebacteria are found in extreme environments like geysers, volcanoes, deep underground, in the salt flats of Utah, or even the Arctic tundra. The second type of bacteria is known as archaebacteria. Archaebacteria are found in extreme environments like geysers, volcanoes, deep underground, in the salt flats of Utah, or even the Arctic tundra. Examples of Archaebacteria would include: Halobacterium, Examples of Archaebacteria would include: Halobacterium, Methanothermus, and Thermoproteus. Archaebacteria are often known as being Halophilic, Thermophilic, and Methanogens (anaerobic and they die in the presence of oxygen). Archaebacteria are thought to be some of the oldest species of organisms that have ever lived on earth. We have fossil remnants of them that go back 3.5 billion years.

19 Protista About 250,000 Species of Protists About 250,000 Species of Protists Protists can be unicellular or multi-cellular and Eukaryotic Protists can be unicellular or multi-cellular and Eukaryotic 1 st Eukaryotic Protists appeared about 1.5 billion year ago 1 st Eukaryotic Protists appeared about 1.5 billion year ago Some protists have to get their energy from other organisms and some have to make their own food Some protists have to get their energy from other organisms and some have to make their own food Most protists are microscopic Most protists are microscopic

20 Protists Three Types of Protists Three Types of Protists Protozoa (Animal like protists) Protozoa (Animal like protists) Algae(Plant like protists) Algae(Plant like protists) Slime molds (Fungi like protists) Slime molds (Fungi like protists) Brain Pop Protist Video Brain Pop Protist Video

21 Protists - Protozoa Protozoans are microscopic protists that have several characteristics that are like animals. Protozoans are microscopic protists that have several characteristics that are like animals. This is a protozoan called a Daphnia, commonly referred to as a water flea. This is a protozoan called a Daphnia, commonly referred to as a water flea.

22 Protista - Protozoan This is a diagram of the body structures of a paramecium. As you can see, they are pretty complex for such little creatures.

23 Protozoan-Ameba Amebas move and feed by forming pseudopods which are temporary bulges of the cell membrane that fill with cytoplasm. A pseudopod is also known as a false foot. Its almost as if the ameba is just sliding around as it extends itself. This is also how the ameba eats because it can surround food particles with its body and consume them. This process is called phagocytosis.phagocytosis Amebas also have a contractile vacuole that helps them move as they can take in water and then expel it Ameba in Motion Video Ameba in Motion Video

24 Protozoan-Paramecium Paramecium have structures called cilia which are hair-like projections that move like tiny oars. The cilia help the paramecium move. Paramecium eat when they use their cilia to sweep food particles towards the area of their body called an oral groove. This area acts as a mouth as organisms are able to consume small food particles generally dissolved in water. Paramecium are some of the most common protists found in water.

25 Algae-Euglenoids Euglenoids are green and use a whip like structure called a flagellum to whip themselves through aqueous solutions. Euglena are photosynthetic organisms that rely on the sun for energy. They have a structure in their body called an eye spot that helps them locate light.

26 Protists - Algae Algae are protists that have a few characteristics in common with plants. Algae make their own food using photosynthesis. This is a Green Algae

27 Protista – Slime Molds Slime and Water Molds have a few characteristics in common with fungi This is a common slime mold that can grow on a forest floor

28 Macroscopic Protista Some Protista are actually quite large and can be seen easily with the naked eye. Some Protista are actually quite large and can be seen easily with the naked eye.

34 Kingdom Plantae 250,000 Species 250,000 Species Eukaryotic and Multicellular Eukaryotic and Multicellular Make their own food during photosynthesis. Make their own food during photosynthesis. Include: Mosses, ferns, grasses, gymnosperms and angiosperms. Include: Mosses, ferns, grasses, gymnosperms and angiosperms. Plants have a cell wall and are made of cellulose Plants have a cell wall and are made of cellulose

35 Kingdom Plantae During photosynthesis, plants take in carbon dioxide, water and use energy from the sun to form sugar and oxygen. During photosynthesis, plants take in carbon dioxide, water and use energy from the sun to form sugar and oxygen. Plants are green because of the pigment chlorophyll that they use in photosynthesis. Plants are green because of the pigment chlorophyll that they use in photosynthesis.

36 Kingdom Plantae Bryophytes or Mosses

37 Ferns Ferns

38 Kingdom Plantae Grasses Grasses

39 Kingdom Plantae Gymnosperms or Cone bearing trees Gymnosperms or Cone bearing trees

40 Kingdom Plantae Angiosperms or flowering plants Angiosperms or flowering plants

41 Kingdom Animalia 1,000,000 Species Animals are divided into two main groups –Vertebrates: Animals having a backbone. –Invertebrates: Animals without a backbone. *Humans belong to the Kingdom Animalia!

42 Kingdom Animalia The animal Kingdom contains the following different groups of animals: –Amphibians-Echinoderms –Arthropods-Mammals –Birds-Mollusks –Fishes-Reptiles –Sharks-Insects

43 Kingdom Animalia The phylum arthropoda is the largest group of organisms in the animal kingdom. If we were able to identify and classify all of the unknown insects in the rain forests and elsewhere, scientists estimate that there would be 10 million different kinds of arthropods!

44 Kingdom Animalia - Amphibia Amphibians The word amphibia in greek means double life. Amphibians spend at least part of their lives in water!

45 Kingdom Animalia - Arthropods Arthropoda Bilateral Symmetry There are five main groups of arthropods: horseshoe crabs, arachnids, crustaceans, centipedes and millipedes, and insects.

46 Kingdom Animalia - Birds Birds Have feathers and lay eggs.

47 Kingdom Animalia - Fishes Fishes Spend their lives in water. Have gills

48 Kingdom Animalia - Echinodermata Spiny skin, 5 part body, internal skeleton, tube feet. Starfish, urchins, sand dollars, sea cucumbers, sea lillies.

49 Kingdom Animalia - Mammals Have hair and mammary glands, give birth to live young. Nearly all are warm blooded. We belong to this group.

50 Kingdom Animalia – Mollusca Animals with soft bodies. Have a toothed tongue. Many mollusks have shells. Mollusks include: snails, octopi, squid, clams, mussels and others

51 Kingdom Animalia - Reptiles Reptiles are animals that have scales, breathe air and lay eggs. Reptiles include: Snakes, lizards, alligators, crocodiles, turtles,

52 Kingdom Animalia - Sharks Sharks have been on the earth for a very long time and they have changed relatively little over the years. Shark can have as many as 300 teeth!

53 Kingdom Animalia - Insects Insects are part of the phylum arthropoda. This means that they are invertebrates. They have no backbone, but they do have an exoskeleton and 3 pairs of jointed appendages In Latin the word insect means segmented.

54 Domains of Life (Old Classification System) There used to be an 8 th level of classification in which there was a classification group called Domain that was up above Kingdoms. The 3 Domains of Life were Archae, Eukarya, and Prokarya. Eukarya and Prokarya were used to reference whether or not cells had a nucleus.
