Robert Hooke
|
English scientist who formulated the law of elasticity and proposed a wave theory of light and formulated a theory of planetary motion and proposed the inverse square law of gravitational attraction and discovered the cellular structure of cork and introduced the term `cell' into biology
|
Cell
|
The basic structural and functional unit of all organisms; they may exist as independent units of life (as in monads) or may form colonies or tissues as in higher plants and animals
|
Cell theory
|
Refers to the idea that cells are the basic unit of structure in every living thing
|
Nucleus
|
A part of the cell containing DNA and RNA and responsible for growth and reproduction
|
Eukaryote
|
An organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria
|
Compound light microscope
|
A microscope that allows light to pass through a specimen and uses two lenses to form an image. An instrument that uses two or more lenses and a beam of light to magnify small objects.
|
Cytoplasm
|
The material or protoplasm within a living cell, excluding the nucleus
|
Organelle
|
Any of a number of organized or specialized structures within a living cell
|
Electron microscope
|
A microscope with high magnification and resolution, employing electron beams in place of light and using electron lenses
|
DNA
|
Deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information
|
Vacuole
|
A space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid
|
The cell is like a factory
|
Referes to each part of the cell having its own duties ti make it work
|
Lysosome
|
An organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane
|
Ribosome
|
A minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins
|
Golgi apparatus
|
A complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport
