BIOLOGY GLOSSARY


Ecosystem: (Required word)


A system formed by the interaction of a community of organisms with their physical environment.


An example of an ecosystem is Trees, a lake or in the ground.


Data: (Required word)


A collection of facts from which conclusions may be drawn


Hypothesis: (Required word)


A tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation.


Photosynthesis: (Required word)


The process that light energy, carbon dioxide and water are converted in to complex carbohydrates and oxygen buy the use of chlorophyll.


An example of photosynthesis is a plant harnessing the suns energy to make complex carbohydrates.


Autotroph: (Required word)


An organism capable of making its own food, i.e. plants, algae and some bacteria


Autotrophs achieve this buy either harnessing the suns rays or by creating chemical energy.


Examples of an autotroph are i.e. plants, algae and some bacteria.


Classification: (required word)


The grouping of organisms into categories that will place each group of animals or plants in its place this is also called taxonomy.


An example of a classification is a blue whale belongs to the kingdom Animalia.


Respiration: (Required word)


The brake down of molecules in which energy is used, if oxygen is used the process is aerobic; if not, it is anaerobic.


An example of respiration is breathing.


Adaptation: (required word)


A change in an organism resulting from natural selection or natural disaster to suite it’s surrounding.


An example of an adaptation is that Prime Apes and Humans have an opposable thumb.


Species: (required word)


A fundamental category of taxonomic classification, ranking below a genus or subgenus and consisting of related organisms capable of interbreeding.


An example of a species is M. tuberculosis, which is tuberculosis Bacterium.


Appendage: (required word)


A part or organ that is connected to the main part of the body such as an arm, fin, tail or leg which is joined to the main part of the body.


An example of this is the legs on a human that help us to walk.


A Homo Sapiens Arm


Habitat: (required word)


The area or environment where an organism(s) would normally lives or occur.


An example of this is the ocean.


Consumer: (required word)


A heterotrophic organism that ingests other organisms or organic matter whether it may be dead or living in a food chain.


An example of a consumer is a Homo Sapien


Taxonomy: (required word)


The classification of organisms in an ordered system that indicates natural relationships.


An example of this is


Kingdom, phylum, class, order, family, genus, species or


Way of remembering King Philip came over from Geese (to) Spain



Detritivore (required word)


A organisum that gathers its energy from eating detritus in a ecosystem


An example of a detritivore is bacteria.


Decomposer: (required word)


An organism, often a bacteria or fungus that feed on and breaks down dead plant or animal matter, as a result making organic nutrients available to the rest of


the ecosystem.


An example of a decomposer is a worm.


Chlorophyll (in class)


Any green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria.


An example of this is a green pigment on the leaf of a plant.



Chlorophyll


Prokaryote: (in class)


An organism of the kingdom Monera or Prokaryotae comprising the bacteria and cyanobacteria, characterized by the absence of a distinct, membrane-bound nucleus or membrane-bound organelles.


Cell: (in class)


The smallest structural unit of an organism that is capable of independent functioning, consisting of one or more nuclei, cytoplasm, and various organelles all surrounded by a semipermeable cell membrane.


Eukaryote: (in class)


A single-celled or multicellular organism with cells contains a distinct


Membrane-bound nucleus.


Osmosis: (in class)


Diffusion of liquid through a semipermeable membrane, from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane.


The diffusion of a liquid through a semi-permeable membrane.


Diffusion: (in class)


The act of passing by osmosis through animal membranes, as in the distribution of poisons, gases, etc., through the body. Unlike absorption, diffusion may go on after death, that is, after the blood ceases to circulate.


Mitosis: (in class)


The process in cell division by which the nucleus divides, consisting of four stages, prophase, metaphase, anaphase, and telophase, and normally resulting in two new nuclei, each of which contains a complete copy of the parental chromosomes.


Bacteria: (in class)


Any of the unicellular prokaryotic micro-organisms of the class Schizomycetes, which vary in terms of morphology, oxygen and
