The more scientists worked on finding out more about the cell the more they learned about cells. Plus the microscopes became more advanced then the more they could see what was in the cell.
(This is only a middle school answer!!!)
Although Hooke and Leeuwenhoek were the first to report observing cells, the importance was not realized until about 150 years later. Biologists then began to organize information about cells into a unified understanding. from Modern Biology. Holt, Rinehart, and Winston. Chapter 4 "Cell Structure and Function," sub-heading "Cell Theory."

Because the microscopes Hooke had were useless for detail and it took 200 years to get a good enough microscope. Along with this nobody thought cells of any importance until later.
becausehoraswas tooimportantto be invented and the scientist coudnt focus on keep on doing the cell theory so that means it couldnt be developed in time or early.
More scientists worked on finding out about cells
because there wasnt microscopes at the time
because the technology they had day then was not as advaced as what we have today and
A great multitude of organisms had to be examined and found to be made of cells before the statement that all living things are made of cells could be trusted.
Because it was probably hard to formulate the cell
All life actives take place in cells #one answer
It depends on the technique you employ. In conventional breeding it may take several years. By genetic engineering and tissue culture it may be developed with in two years or even less.
They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
Felix Dujardin is a French biologist and cytologist who is known for his studies in the classification of protozoans and invertebrates. He is also one of the scientists who contributed to cell theory. During 1665, scientist Robert Hooke coined the term, 'cell.' This opened up a whole new world as far as biology was concerned in the scientific realm. Dujardin was able to take the cell theory a bit further and was the first to group single-cell animals and name them as 'Rhizopoda.' They are now called protozoans
A food vacuole can take up much of the space on the inside of the cell. This is because it acts as storage for the cell.
190 years passed between the discovery of cells and when the third cell theory was added.
150 years, after microscopes were invented.

Field theory is the belief that in order for change to take place the total situation must be studied and figured. This was a term or method of study that was developed by Kurt Lewin.

It varies from years to forever (or never).

The Motorola Theory is a wonderful phone. I know from experience, that this cell phone does not take alot to figure out. When you turn the phone on majority of the time a menu button will be on the phone.
