* Diploid: Means the organism has two sets of chromosomes.

* 11 chromosomes: This means the organism has 11 pairs of chromosomes (22 total).

Sister Chromatids

* Sister chromatids are identical copies of a chromosome that are joined together. They are created during DNA replication before cell division.

* Each chromosome has two sister chromatids.

Therefore, a diploid organism with 11 chromosomes has 11 pairs of sister chromatids in each cell.
