An atom is the smallest particle of an element that contains the chemical properties of that element. Learn about atoms and their components (protons, neutrons, and electrons) in this program.
This lookup displays all the elements in the periodic table, sorted by symbol. Also included are the element name, atomic mass, atomic number, and electron configuration. This is a must for anyone learning the periodic table.
See how well you remember the chemical symbols with this quiz. At a button-click you get ten more names of elements from the periodic table, each with four choices of chemical symbols for you to choose. Can you get them all?
Electron configuration in an atom is organized into orbitals and differently shaped subshells. Learn about the s subshell, p subshell, d subshell, and f subshell (and more) in this interactive tour.
Learn the symbol, electron shell configuration, atomic mass, and other important details for each chemical element with this interactive flashcard program.
Examine chemical symbols, atomic masses, electronegativity, electron shell configuration, and more in this printable interactive periodic table of the elements. We have all the elements discovered thus far, and instructions on how to read the table.
Ever wonder how to actually use the periodic table of elements? Get a detailed overview of the various sections on the periodic table including electron shell configuration, atomic mass, chemical symbols, electronegativity, and more with this tutorial.
Active transport is the mediated process of moving molecules and other substances across membranes. Use this tutorial to learn about active transport, including such key terms as adenosine triphosphate (ATP), carrier mediated transport, and concentration gradients.
Carrier proteins help specific molecules or ions pass through the plasma membrane. Do you know how carrier proteins work? This interactive tutorial will help you to absorb this key concept.
Diffusion is the net movement of particles (atoms, molecules, or ions) from a highly concentratd region to a region of low concentration. Understanding diffusion through a membrane is a key biology concept. Take this interactive tour to help you master the process and terminology.
Endocytosis is a cellular process where cells absorb molecules or substances from outside the cell by engulfing it with the cell membrane. This tutorial explains the cellular processes involved in endocytosis, including phagocytosis, pinocytosis, and receptor-mediated endocytosis.
The lipid bilayer is an organic compound that is insoluble in water but soluble in nonpolar solvents, providing the basic impermeable structure of the membrane. Explore the process, structure, and function of an plasma membrane's lipid bilayer with this interactive tutorial.
How much do you know about the three types of membrane proteins? Find out about integral proteins, transmembrane proteins, and peripheral proteins with this interactive tutorial.
In biological terms, osmosis is the diffusion of water though a membrane to a region with a lower concentration of water. Do you understand how osmosis works in a plant cell? Take this interactive tour to help you master the concept and terminology.
In biological terms, osmosis is the diffusion of water though a membrane to a region with a lower concentration of water. Do you understand how osmosis works in an animal cell? Take this interactive tour to help you master the concept and terminology.
Passive transport is the cellular process of moving molecules and other substances across membranes. Learn about diffusion, facilitated diffusion, filtration, and osmosis in this Passive Transport tutorial.
The plasma membrane is a selectively permeable membrane made up of a lipid bilayer and proteins surrounding the cell. Explore the process, structure, and function of an animal cell's plasma membrane with this interactive tutorial.
The plasma membrane is a selectively permeable membrane made up of a lipid bilayer and proteins surrounding the cell but inside the cell wall. Explore the process, structure, and function of a plant cell's plasma membrane with this interactive tutorial.
Use this tutorial to explore the growth and division processes for plant cells -- interphase, mitosis, prophase, metaphase, anaphase, telophase, and cytokinesis.
