Classification

Classification: 1. Complete part A of the lab on pg 354-355 in your text book. Find picture of organism and a dichotomous key to use for your classmates and post to the Wiki. [] 2. Define biodiversity. Why is it important that we preserve biodiversity? Darryl Davidson Biology 2nd 9/ 28/ 2010 Biodiversity is the variation of life forms within a given ecosystem, biome, or for the entire Earth. Biodiversity is often used as a measure of the health of biological systems. It is the reason that all organisms can coexist in the world. If one organism dies, many more might die because of the first organism. Biodiversity is important because each organism needs to complete their niche. 3. Describe Linnaean’s system of classification. In the 1750s, Swedish botanist Carl von Linné (who is known by the Latin form of his name, Linnaeus) developed a system to classify all living things. Each living thing has two scientific names, a genus and a species name. The scientist who first describes a new organism (any living thing) names it. Since Linnaeus began using this system, over a million species have been named. (Domain), Kingdom, Phylum, Class, Order, Family, Genus, Species

4. What are the rules of binomial nomenclature? Give an example.

Johnathon Martin
 * 1) 4. Answer – Step 1: use the genus and species. Step 2: Capitalize Genus and lowercase species. Step 3: Italicize the names. Example: //Homo sapiens// is a human //, Patella vulguta// is a sea snail.

5. Find a cladogram on the Internet and explain which organism are most closely related. Define the common ancestor and pick out the common ancestor on the cladogram. Dylan Patel Organisms that are closest together are the closely related. Common ancestors are an ancestor shared between two organisms. Like below the birds and Devinychus

6. Describe the characteristics of the kingdom Archaebacteria. Describe the way they obtain energy, reproduce, their environment, they types of cells, if they are multicellular or unicellular.

Archeabacteria are prokyrotic, unicellular organisms. They obtain energy from salt. They reproduce asexually through binary fission. Archeabacteria live in extreme environments. Some types of Archeabacteria are Methogens, Thermophiles, and Halophiles.

7. Describe the characteristics of the kingdom Eubacteria. Describe the way they obtain energy, reproduce, their environment, they types of cells, if they are multicellular or unicellular. Prokarotic, Autotrophic and Heterotrophic, unicellular, eu means true, they produce asexually and sexually, alive since about 21 billion years ago, they cause tooth decay and food poisoning. Some of the bacteria is called cyano bacteria and they live in the ocean and they make their own food.

8. Describe the characteristics of the kingdom Protista. Describe the way they obtain energy, reproduce, their environment, they types of cells, if they are multicellular or unicellular. Protists obtain energy by phagocytosis Protists reproduce asexually or sexually. They have a wet enviroment. Their cell type is both autotrophic and heterotrophic. They are also multicellular and a eukaryote.

9. Describe the characteristics of the kingdom Fungi. Describe the way they obtain energy, reproduce, their environment, they types of cells, if they are multicellular or unicellular.

- Fungi are multicellular, eukaryotic organisms. They reproduce by sporing and live in moist, dark places. They obtain energy by being absorptive heterotrophs, which means they get energy by absorbing energy from consuming other organisms. Some examples of fungi are mushrooms, yeasts, and molds.



10. Describe the characteristics of the kingdom Plantae. Describe the way they obtain energy, reproduce, their environment, they types of cells, if they are multicellular or unicellular. The kingdom plantae consists of eukaryotic multicellular plants with cell walls made of cellulose. There are some parasitic species of plants but most are autotrophic. They use photosynthesis as a source of energy, how they get their food, and they develop from embryos. Most plants live on land such as ferns, mosses, and flowering plants. Plants reproduce both asexually and sexually. They reproduce asexually by budding and fragmentation. They reproduce sexually by the assistance of animals (a good example of this is honey bees and flowers which is pollination). Plants allow us to make items such as coffee, chocolate, soda, and some medicines. Plant types include carnivorous plants (Venus Fly Trap) flowering plants (Lilies,Grasses,Orchids ), and also trees.

11. Describe the characteristics of the kingdom Animalia. Describe the way they obtain energy, reproduce, their environment, they types of cells, if they are multicellular or unicellular.

Characteristics: eukaryotic, multicellular, heterotrophic organisms that develop from embroys. Animals obtain energy by the food they eat and consuming other organims. The many known methods of reproduction are generally placed into one of two classifications, sexual and asexual reproduction. Animals reproduce sexually. The environment in which an animal lives is referred to as their habitat. A habitat includes both biotic and abiotic living components of an animal's environment. Animal's are multicellular.
