Question

match the following cells with their appropriate ploidy level. drag each item on the left to its matching item on the right. a bacterium with a single circular chromosome silk glands of the commercial silkworm, containing over a million copies of the genome a human cheek cell rye grass with four sets of chromosomes tetraploid diploid haploid polyploid

Explanation:

Haploid cells have one set of chromosomes, diploid have two sets, tetraploid have four sets, and polyploid refers to cells with more than two sets of chromosomes. A bacterium with a single circular chromosome is haploid as it has one copy of genetic material. Silk glands of the commercial silkworm with over a million copies of the genome are polyploid. A human cheek cell is diploid as human somatic cells have two sets of chromosomes. Rye grass with four sets of chromosomes is tetraploid.

Answer:

a bacterium with a single circular chromosome - haploid
silk glands of the commercial silkworm, containing over a million copies of the genome - polyploid
a human cheek cell - diploid
rye grass with four sets of chromosomes - tetraploid
