Famous Scientists
Although these two German scientists believed that all living things are made of cells, they supported the predominant theory of cellular origin believing that cells could freely and spontaneously generate from component parts, according to a crystallization process.
Who are Matthias Schleiden and Theodor Schwann.
Atomic structure underlies both living and non living things, but this word describes the basic structure of all living things.
What are cells?
The interplay of between facts, theories, hypotheses, and experiments form a cyclical method of scientific inquiry.
What is the Cycle of Scientific Enterprise?
This Greek word for indivisible refers to the fundamental unit of matter, composed of protons, neutrons, and electrons.
What is the atom?
An instrument that bends light so as to visualize microscopic structures on a cellular level.
What is a light microscope?
In 1832, this Belgium scientist made observations on the silkweed plant, showing cells at the end of a filament dividing into identical cells.
Who is Barthelemy Dumortier?
This fundamental building block of life is a self contained living factory surrounded by a membrane, containing genetic material and capable of self-replication.
What is a cell?
This word describes our best current explanation for a body of data (facts), yet are subject to change from new data.
What are theories?
This is the term for a combination of atoms that are chemically bonded to create an entity with unique properties.
What is a molecule?
An instrument used to visualize entities that are too small to be seen.
What is a microscope?
French aristocrat who survived the French Revolution, in 1824 was the first to describe the cell as the fundamental unit of structure and physiology in plants.
Who was Henri Dutrochet?
A network of highly folded membranes where chemical synthesis of many types of biomolecules take place with two types called rough and smooth.
What is the endoplasmic reticulum?
Although facts are subject to change based on new data that can over time change the theory, this word defines that which does not change and is know through direct observation such as the distinctions between male and female and special revelation in the Bible.
What is truth?
This positively charged subatomic particle found in the nucleus of an atom whose number in an atom determines its identity.
What is a proton?
In the 1930s, physicists Ernst Ruska and Max Knoll constructed this observational tool with a resolution that far exceeds the that of a light microscope using a beam of electrons, rather than light, to generate an image of a sample.
What is a electron microscope?
In 1665, this English scientist observed cork under a crude microscope and the small chambers he saw resembled the wax cells of an honeycomb and so he coined the term "cell".
Who was Robert Hooke?
Named for this Italian scientist who discovered a stack of separate, stacked membrane sacs, through which newly synthesized molecules are modified, packaged, and transported.
What is the Golgi Apparatus?
This word describes an informed prediction based on a theory which can then be tested by experiments.
What is an Hypothesis (plural: Hypotheses)
These negatively charged subatomic particles that are found in the orbitals of the atom whose interactions of electrons are what determine an element's chemistry.
What are electrons?
This instrument uses beams of electrons to produce images of entities on the cell and organelle level; a very thin sample is observed, allowing organelles to be resolved with great clarity.
What is a transmission electron microscope?
In 1676, a Dutch draper examining fabrics built and developed a more powerful microscope, and so he observed pond water, blood, and sperm, seeing tiny moving microorganisms and animal cells that he called "animalcules".
Who was Antonie van Leeuenhoek?
Disorders in this membrane-bound organelle that maintains hydrolytic, enzymes, in an acidic environment, for the purpose of breaking down and recycling materials can result in Gaucher disease, Tay-Sachs disease, Fabry disease, Hunter Syndrome among other disorders.
What is the lysosome?
This word best describes how theories result in our best explanations of what we observe in nature.
What are models?
When partial charges on one molecule are attracted to the opposite partial charge on the neighbouring molecule and whose bonds form in molecules that have strongly polar bonds, those between H and O, N, or E.
What is Hydrogen Bonding?
This scientific tool is a form of microscopy with an even higher resolution that able to see individual atoms by blasting an electron from a distance using a tiny probe that is able to come extremely close to a surface. This close surface allows the electron to tunnel through the sample imaging individual atoms on that surface.
What is the scanning tunnelling microscope?
