Lesson 38
Classification System
| Question | Answer |
|---|---|
| Taxa | there are seven groupings in the classification system, starting with kingdom and ending with species |
| Euglena | a single-celled organism found in the Protista kingdom, they can make their own food through photosynthesis and it can also absorb it, this makes this organism both an autotroph and a heterotroph |
| Monera | the kingdom of single-celled organisms that are prokaryotic |
| Prokaryotic | describing cells that lack a nucleus or membrane-bound organelles |
| Mitochondria | organelles inside of a cell that are the sites for cellular respiration, they take glucose and oxygen and convert these to ATP energy |
| Chloroplast | a structure found in plant cells that contains chlorophyll, a photosynthetic pigment |
| Binary Fission | a type of asexual reproduction where a single cell divides into two identical daughter cells |
| Asexual Reproduction | reproduction where a single organism produces offspring without the contribution of another organism, the offspring are identical to the reproducing organism |
| Protista | a kingdom that is made up of unicellular, eukaryotic organisms. Paramecium, amobea, volvox, and euglena belong to this kingdom |
| Nucleus | the control center of the cell, it contains DNA which controls the activities of the cell |
| Autotrophs | organisms that can produce their own food, usually through photosynthesis |
| Multicellular | an organism composed of many cells |
| Chitin | polysaccharide that makes up the cell walls of fungi |
| Saprophytes | plants that get their nourishment from dead or decaying organic matter |
| Parasitic | describing an organism that survives by living and feeding off of another living organism causing the host organism harm |
| Plantae | also known as the plant kingdom, it consists of organisms that are multicellular, eukaryotic, and photosynthetic |
| Animalia | the kingdom in which organisms are mulicellular, eukaryotic, heterotrophs that lack cell walls |
| Taxonomy | the science of naming and organizing organisms into groups based upon their characteristics |
| Binomial Nomenclature | a classification system in which each organism is designated by a two-part scientific name using Genus and species names, written in italics |
| Dichotomous Key | a tool used to properly identify an organism using opposite characteristics of that organism, for instance a characteristic could be “cell wall” or “no cell wall” |
