Term
Taxonomy
Definition
Study of the naming, classification, and organization of organisims
Term
C. Linnaeus
Definition
Began the systemic with the Kingdom organization and Binomial Nomenclature
Term
Binomial Nomenclature
Definition
Two name system: in living systems Genus and species
Term
Monera
Definition
Kingdom of Eubacteria and Archaea the prokaryotic organisms
Term
Protista
Definition
Single celled, both hetero and autotrophic, and eukaryotic organisms
Term
Fungi
Definition
Multicellular, absorbers, decomposers, cell walls made of chitin, fruiting bodies, and both asexual and sexual reproduction
Term
Plantae
Definition
Multicellular, autotrophic, highly organized organisms, immobile, and uses sexual reproduction
Term
Animalia
Definition
Multicellular, eukaryotic, mobile, sexual, and heterotrophic organisms that can have many modes of living and niches.
Term
Virus
Definition
A submicroscopic infectious particle that is produced of a protein coat, a nucleic acid, and the ability to reproduce and mutate with the help of a host cell. However, it is not considered to be alive.
Term
Capsid
Definition
Proteinacous outercoating of a virus
Term
Lytic Cycle
Definition
Virus immediately takes over the host cell and produces new viruses until the cell lysis occurs
Term
Lysogenic Cycle
Definition
Virus cycle where the virus lies dormant before production occurs
Term
Endocytosis
Definition
Use of vessicles during active transport to bring materials in to the cell: including food, viruses, foreign bodies, and nutrients
Term
Vaccine
Definition
Stimulating an immune response without causing a disease. This prevents virus infections.
Term
Budding
Definition
Asexual reproduction involving the growth of a new cell, organism, or virus off the side of another. Ex. Retrovirus reproduction, coral reproduction, and yeast.
Term
cell
Definition
smallest unit of life and living organization
Term
Organism
Definition
A living thing. Example:1 Ameba, Person, or a Turkey
Term
Organelle
Definition
Small functional part of an Eukaryotic cell. Ex. Mitochondria, Golgi Apparatus, Nucleus
Term
Tissue
Definition
Same or several cells working together to perform a specific function. Ex. Cardiac Muscle, Skin, Bone
Term
Cell Membrane
Definition
The portion of the cell that separates it from the outside environment. Made from carbohydrates, lipids, and proteins. Primary structure called the Phospho-lipid bilayer
Term
Phospho-lipid Bilayer
Definition
Part of the cell membrane made of a lipid with a phosphate head creating a hydrophobic (water scared) and hydrophilic (water liking) layer
Term
Osmosis
Definition
Movement of water through a semipermeable membrane
Term
Diffusion
Definition
Free movement of concentrated substance throughout an area liquid gas or solid. Ex. Adding a drop of food coloring to snow
Term
Active Transport
Definition
When ATP is consumed by a cell transporting items in or out of the cell membrane
Term
Notochord
Definition
The nerve tissue highway in vertebrates that disperses messages from the central nervous system to the rest of the body
Term
Vertebrae
Definition
Bones that surround and protect the Spinal or notochord
Term
Mollusk
Definition
Invertebrate phylum with soft bodies, external shells, with a radula, and mostly aquatic
Term
Arthropod
Definition
Invertebrate phylum with exoskeleton, segmented body, and metamorphosis
Term
Echinodermata
Definition
Invertebrate phylum with adult stage radial symmetry, rough skin, regeneration, and all marine
Term
Cnidaria
Definition
Invertebrate Phylum with two tissue layers, radial symmetry, two life stages medusa and polyp
Term
Porifera
Definition
Invertebrate phylum with assymetry, organized only on cellular level (no tissues), species specific spicules
Term
Platyhelminthes
Definition
Invertebrate worm phylum known as flat worms. Mostly parasitic or aquatic first layers headed toward a coelom.
Term
Nematodes
Definition
Invertebrate phylum of worm that is called round. Has a pseudocoelom and fill all niches in an ecosystem
Term
Annelida
Definition
Invertebrate phylum of segmented worms. First full coelom and mesoderms with a cavity for organs.
Term
Mitochondria
Definition
organelle known as energy factory of cell
Term
Golgi Apparatus
Definition
responsible for moving molecules made in the cell to their home locations or out of the cell in vessicles
Term
vessicle
Definition
organelle that carries items in active transport
Term
Endoplasmic Reticulum
Definition
Where the amino acids from tranlation are assembled and transported either with or without ribosomes
Term
Nucleus
Definition
The functional epicenter of the cell and storage of DNA
Term
Nucleolus
Definition
In the nucleus and is made of RNA and protein, is responsible for the creation of rRNA
Term
Vacuole
Definition
Storage of food materials
Term
Ribosome
Definition
responsible for the assembly of proteins
Term
Lysosome
Definition
vessicle type structure responsible for the enzymatic breakdown of cell invaders
Term
cytoskeleton
Definition
touch material that helps the cell stay in the three dimensions and not fall and collapse
Term
Chromosomes
Definition
The structures that the DNA is stored in during the cell cycle before mitosis
Term
Spindles fibers
Definition
Are used to pull the sister chromatids apart in anaphase of mitosis
Term
Centrosomes
Definition
Structures that hold the sister chromatids together
Term
Centrioles
Definition
Used to anchor spindles during Mitosis
Term
Mitosis
Definition
4 phase stage of the cell cycle when cell division occurs
Term

Definition
Process that forms the gametes of an organism
Term
DNA
Definition
Deoxyribo Nucleic Acid the storage code for the phenotypes and fucntions of organisms
Term
