Classification and Symbiosis

QuestionAnswer
Inconsequential Symbiosis In this symbiosis, one organism is helped while the relationship has no effect of the other. Example: The Water Buffalo and the EgretThe Egret benefits from the work of the buffalo, whereas the buffalo does not even know the egret is there.
Beneficial Symbiosis Both organisms benefit from the relationship. Example: The Water Buffalo and the Bacteria. In this case the bacteria do not need to hunt for food or worry about being eaten by predators AND the buffalo is able to digest its food easier.
Harmful Symbiosis One organism is harmed while the other benefits. The water Buffalo and the Tapeworm. worm is able to survive by taking what it needs from the buffalo. The buffalo worked to take in and process the food, only to have part of it stolen .
Necessary Symbiosis In this symbiosis, the organisms not only help each other, but would not be able to survive without each other. Example: Lichen. Algae is given a safe place to live while the fungus is fed by the algae.
Both plants and animals compete, but what are they competing for and how is it done? Survival. Plants and animals both compete for an area’s limited resources. Plants compete for nutrients in the ground, sunlight, an area to grow, pollinators, mates, and water. Animals compete for food, shelter, water, hunting grounds, and mates.
Know the order of the classification system Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Kingdom Highest and most general grouping of organisms.
Species Lowest and most specific grouping of organisms.
Know that as you travel further down in the classification system that the organisms become more similar. Know that as you travel further down in the classification system that the organisms become more similar.
Archaebacteria Single-celled organisms. Able to survive in extreme environments. Do not have a true nucleus. Many do not need oxygen or sunlight to survive.
Eubacteria Single-celled organisms. Do not have a true nucleus.
Protist Can be single-celled or multi-cellular. Most single-celled organisms. Most live in colonies.
Fungi Can be single-celled or multicellular. Plant like structures but cannot make their own food. Plant-like structures but do not make their own food. Need a host to absorb nutrients from.
Plants Multicellular and can make their own food in the form of sugars.
Animals Multicellular and get their food by eating other organisms.
Vertebrates Have backbones that surround and protect the spinal column.
Invertebrates Do not have backbones that surround and protect the spinal column.
Mammal Phylum Hair or fur, Warm-blooded, Mother’s milk
Reptile Phylum Scales, Cold-blooded, Hatch from eggs
Bird Phylum Feathers, Warm-blooded, Hatch from eggs
Amphibians Phylum Soft skin, Cold-blooded, skin absorbs water and oxygen.
Fish Phylum Scales usually, Cold-blooded, Gills
Are most animals on Earth considered Vertebrates or Invertebrates? The majority of animals on Earth are classified as Invertebrates.
Mosses Phylum Non-vascular, Do not have seeds, Do not have flowers.
Ferns Phylum Vascular, Do not have seeds, Do not have flowers.
Conifers Phylum Vascular, Do have seeds, Do not have flowers.
Flowering Plants Phylum Vascular, Do have seeds, Do have flowers.
How are fungi different from plants? Fungi are not able to make their own food even though they have many plant-like structures.
How and why has Carolus Linnaeu’s classification system changed since it was first developed in 1735? As new organisms are discovered the classification system is updated or changed in order to accommodate these new organisms as they may not fit in current categories.
3 benefits to scientists all using the same classification system 1. The same name for an organism to stop confusion or multiple names for the same organism. 2. It lets scientists know something about the organism due to all organisms in that category share common characteristics. 3. Helps to organize information.
