|
Centriole
|
Found in the cells of animals and some algae and fungi; two pairs on centrioles play an important roll in cell reproduction.
|
|
|
Chloroplast
|
Double walled organelle found in plants and some algae; functions in photosynthesis to trap light energy.
|
|
|
Chromatin
|
Dense mass of material that is in the nucleusthat is composed of individual chromosones.
|
|
|
Chromosome
|
structure that carries the genes; composed of proteins and DNA.
|
|
|
Cilia
|
Flexible projections extending outward from the cell. that enable locomotion by whiploke motion.
|
|
|
Cytoplasm
|
Substance contained by living cells that is composed of a complex mixture of enzymes, sugars, amd amino acids,these substances are constantly involved with chemical reactions.
|
|
|
Endoplasmic Reticulum
|
Network of interconnected structures found in all eukaryotes; functions include interaccelular transportof proteins and the breakdown of harmful substances.
|
|
|
Eukaryote
|
Cell containing a membrane and a membrane-bound nucleus; the mass majority of living organisms are eukaryotic.
|
|
|
Flagella
|
Long whiplike strands extending from the cell that enable cell locomotion.
|
|
|
Golgi Body
|
flattened, saclike organelle that functions as a processing, packaging, and delivering system in eukaryotes.
|
|
|
Lysosome
|
organelle containing digestive enzymes that break down food and digest worn out cell parts.
|
|
|
Metabolism
|
Sum of all chemical reactions that occur in cells; hydrolosis is one such chemical reaction.
|
|
|
Microfilament
|
Structure of the cytoskeleton in eukaryotes; composed of actin and myosin,it provides structural support, and assists cell movement.
|
|
|
Microtubule
|
Structure of the cytoskeleton in eukaryotes that helps certain organelles move within the cell.
|
|
|
Mitochondria
|
organelles, bound by a double membrane, found in all eukaryotes; mitochondria breaks down organic molecules to release energy for the cell reactions.
|
|
|
Nucleoli
|
Promenent bodies found in the nucleus of eukaryotes.
|
|
|
Nucleus
|
Control area of eukaryotic cells;contains chromatinand a nuceolus.
|
|
|
Prokaryote
|
Cell that lacks a membrane bound nucleus and membrane bound organelles;bacteria and prokaryotes.
|
|
|
Ribosome
|
Organelle composed of RNA and protein; site where proteins are made from amino acids.
|
|
|
Symbiosis
|
Living together of two dissimiliar organisms for ther mutual benefit.
|
|
|
System
|
Group of organs that depend on other organs to complete a biological process such as digestion, respiration, or reproduction.
|
|
|
Tissue
|
In multicellular organisms, a specialized group of cells with the same basic structure that perform the same function.
|
|
|
Vacuole
|
Membrane bound, fluid filled structure functioning in storage, digestion, and maintenance of osmotic balance
|
|
|
Organ
|
A group of different tissues that work together to carry out a particular fuction; the stomach is an example.
