CELL STRUCTURE AND PROTOPLASM 29 



the opposite ends of the cell in numbers 6 and 7, so that each 

 end will have exactly duplicate sets of chromosomes, like 

 the cell from which they came. A wall forms in numbers 8 

 and 9, dividing the cytoplasm to make two new cells. The 

 chromatin returns to the resting condition in number 10. 

 This phenomenon is repeated hundreds and hundreds of 

 times in the development of every plant, in fact it takes 

 place during all the growing periods throughout the life of 

 the plant.
