If not then during cell multiplication how do identical chromosomes (carrying same genetic information) from different parents come close together for exchange of genetic information?

In nature we find that different species have different number of chromosomes. It can be argued (at least theoretically) that the same genetic information could have been stored on a single chromosome strand; why then in nature we find multiple chromosomes. It is obvious that it makes the structure more compact, but does it make multiple chromosomes more efficient than a single strand allowing multiple cross over (for exchange of genetic information during cell multiplication)?

#1. the larger the organism, the larger is the size of its cell.
#2. if a fertilized egg from a mouse has 22 chromosomes, you should expect 22 chromosomes on the muscle cell of the same mouse.
#3.when plants such as strawberries reproduce by sending out runners, they reproduce without sex cells.
