In biology, cell theory is a scientific theory which describes the properties of cells. These cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, also known as cell biology. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1838. This is usually credited to Matthias Schleiden and Theodor Schwann. However, many other scientists like Rudolf Virchow contributed to the theory. Cell theory has become the foundation of biology and is the most widely accepted explanation of the function of cells.
The three tenets to the cell theory are as described below:

The weird and wonderful history of cell theory illuminates the twists and turns that came together to build the foundations of biology. Lesson by Lauren Royal-Woods, animation by Augenblick Studios.
Introduction to cell theory--the idea that 1) all living things are made of one or more cells, 2) cells are the basic unit of life and 3) all cells come from other cells. Explore the roles that Hooke, Leeuwenhoek and others played in developing cell theory.

The Cell Theory Song Mr. Tamez Lyrics: CHORUS All living things are composed of cells Cells are the basic units of structure and function in living things New cells are produced from existing cells VERSE 1 Back then was a guy named Hooke, cut some cork and he had a look Underneath his microscope tiny rooms that he saw in groups Empty rooms that looked like shells He's the one that called them cells Listen up cause we're not done Cell theory had just begun Add one scientist to know the inventor of the microscope Anton von Leeuwenhoek saw cells move and he was like "That's dope" PRE CHORUS Cell theory, cell theory, cell theory, cell theory, cell theory, go! VERSE 2 If you thought this was complete take a breath and have a seat Two scientists to have their say Schleiden and Schwan...
This is the 8th video in our educational series, and the 1st of 4 videos covering what middle school students will be tested on, concerning the cell.
Cells are very small (microscopic) and they units of structure and function for living things. The Cell Theory states the following - All living things are made up of one or more cells. Cells carry out the life processes for living things. New cells arise from old cells through the process of cell division. Cells contain hereditary material (DNA) which contains genetic information. Cells are referred to as the smallest independent units of life. This is because they are the smallest possible unit that can fulfil all of the characteristics of living things.

"The Cell Theory Rap" was an assignment I made my students do...I got carried away making my own rap. First things first the setting is a long time ago The 17th Century to be honest yo' There weren't many games or TV shows Just some nerdy old fools with some microscopes Life without tablets or smart TVs Was spent wisely making discoveries Robert Hooke was one of the dorks That found it fun to stare at cork Dude saw chambers that looked like dorms He called them cells and now that's the norm The cell theory's based on discoveries that were made By these dudes that wore wigs way back in the day Anything that lives has one or more cell And every cell comes from preexisting cells Anything that lives has one or more cells And every cell comes from preexisting cells One last thing tha...

Know you have a problem
Can't you figure it
Suddenly you're lost alone
As your statue splits
Now you walk this cruel world
Lost among it's pain
See all you were in my world
Never to regain
So you misbegotten
Love so quickly fades
So to be forgotten
Turned a grayer shade
See all you were in my world
See all you were in mine
Now you know possession
Million souls to steal
Everynight your death awaits
