Question

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

Explanation:

Haploid cells have one set of chromosomes, diploid have two sets, tetraploid have four sets and polyploid have more than two sets. Bacteria are typically haploid. Human somatic cells like cheek cells are diploid. A cell with over a million - copy genome is polyploid. Rye grass with four sets of chromosomes is tetraploid.

Answer:

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