You should use the same amount of beads for both chromosomes because they need to match in size.
I am assuming you are making a pair of homologous chromosomes out of pop beads, and they should have the same size because they code the same information, the only difference between them is that one comes from the mother and ther other from the father. (Homologous chromossomes have the same genes in the same loci).
The sporophyte are produced before the gametophyte. Is is through the spores that sex cells are made up. The sporophyte contain the genetic material that will used to make the gametes. Therefore, the gametophyte will have half of the genetic material of the sporophyte.
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds.
