BIO Lab Exam #3
| Question | Answer |
|---|---|
| What are the traits of Archaea? | Prokaryotic cells, found in extreme environments |
| What are the traits for Bacteria? | Prokaryotic cells, bacteria with unique biochemical features |
| What are the traits for Eukarya Protists? | Eukaryotic cells, single cell organisms and some simple multicellular organisms, autotrophic or heterotrophic, motile or non-motile |
| What are the traits for Eukarya Plants? | Eukaryotic cells, multicellular, autotrophic, non-motile |
| What are the traits for Eukarya Fungi? | Eukaryotic cells, multicellular, heterotrophic-absorptive, non-motile |
| What are the traits for Eukarya Animals? | Eukaryotic cells, multicellular, heterotrophic-ingestive, generally motile |
| What is a cellular level of organization? | Has different cells specialized for particular functions but does not have tissues or organs |
| What is Organ system Level organization? | Has tissues that work together for a common function to produce organ systems such as the digestive or circulatory system |
| What is symmetrical? | When an animal can be divided into equivalent halves |
| What is bilateral symmetry? | only one way to divide the animal so that both halves are the same size and shape |
| What is Radial symmetry? | can be divided in more than one way |
| What is asymmetrical? | Showing no symmetry |
| What is an incomplete digestive system? | One opening that serves as a mouth an an anus |
| What is a complete digestive systems? | Two openings (mouth and anus) at opposite ends of a tube that is modified along its length for specialized function |
| How do simple animals exchange gases? | Through their surface |
| How do aquatic animals exchange gases? | Through gills, a complex of filaments |
| How do terrestrial animals exchange gases? | Through a series of tubes, tracheae that brings oxygen from their air directly to all the cells of the animal |
| What is a circulatory system? | to transport nutrients to all of the cells and to carry away wastes |
| What type of circulation do cell layered animals have? | Diffusion |
| What is an open circulatory system? | The blood vessels are open ended and the blood flows freely among the cells |
| What is a closed circulatory system? | The blood vessels make a continuous loop and the blood remains contained within them |
| What is a hydrostatic skeleton? | Fluid filled cavity |
| What is an exoskeleton? | a hard covering on the outside |
| What is an endoskeleton? | hard parts such as bones inside the body |
| What happens when an animal has no symmetry? | The animal grows in all directions, usually on the surface of something else, and is non-motile |
| What are phylum porifera? | Sponges |
| What are the characteristics of phylum porifera? | a phylum of simple aquatic invertebrates with no symmetry (few are radial) and only a cell level of organization |
| What are phylum cnidaria? | jellyfish, sea anemones, coral, and freshwater Hydra |
| What are the characteristics of phylum cnidara? | a phylum of aquatic invertebrates with radial symmetry. Cnidarians are characterized by their simple pouch-like body (gastrovascular cavity), tentacles, and stinging cells |
| What are phylum flatworms? | Planaria and tapeworms |
| What are the characteristics of phylum flatworms? | aquatic or terrestrial invertebrates with soft, flattened, worm-like body that posses a distinct head region and an incomplete digestive system |
