what type of cell is this
how did the scientist Schwann come about with this theory
the video is not opening what can i do
what do you by mean by " changes that occur in the external environment"? trow more light please.
THE VIDEO IS NOT OPENING, SO WHAT CAN I DO SIR?
WHAT ARE THE RELIABLE SOURCE TO PROVE THAT THE THEORY OF CELLS BY THOSE TWO SCIENTISTS SCHLEIDEN AND SCHWANN IS TRUE?
HOW CAN CELL REPLICATE OR DUPLICATE IT SELF?
HOW CAN CELL MOVE ABOUT IN IT ENVIRONMENT IN ORDER TO HAVE SURVIVAL?
WHAT SOUND DOES THE WORD CELL MAKE TO US AS HUMAN BEINGS?
how di i get the videos to work, quick time doesn't work with me

Schleiden and Schwann put forward the cell theory in 1839:
* All living things consist of one or more basic functional units -
called "cells" - and their products.
* New cells are produced from existing cells.
The survival of organisms depends on the survival of the cells of which
they are largely composed. Despite changes that occur in the external
environment, the internal conditions of cells must be stable enough for
cell processes to occur.
