The table given in NCERT does not give the differences between chromosomes and genes , instead it shows the similarities between them. Genes are segments of DNA and DNA itself contitute chromosomes.
So, both chromosomes and genes show similar/ parallel behaviour. This is the basis of chromosomal theory of inheritance which was proposed by T Boveri and WS Sutton in 1902 through their experiments.

This theory explains the the parallel behavior between chromosomes and mendelian factor(genes).
Both chromosomes and genes occur in pairs in diploid organism.
Both chromosomes and genes loose their paired condition during gamete formation.

It is the pairing and separation of a pair of chromosomes that ultimately leads to segregation of the pair of factors they carry
