Many plant cells have more than two complete sets of chromosomes in each cell. Explain how this might occur.
otez555 [7]
Polyploidy (more than two complete sets of chromosomes) is not rare among plants. For example, pollen grains may reach female flowers via animals or wind. In some cases, pollen grains from species with 4 complete sets of chromosomes will have 2 sets of chromosomes. Pollen grains may fuse with a female reproductive organ with 1 set of chromosome (so, female plant must have 2 sets of chromosomes). The resulting zygote will have 2 + 1 sets of chromosomes, so the plant will have 3 complete sets of chromosomes.

Alexeev081 [22]

Based on their function, you would expect melanocytes in the skin to have a higher than usual number of ribosomes.

Ribosomes are cell structures that functions as the site of biological protein synthesis. Ribosomes are present in all living cells where they produce proteins required for many cellular functions. Ribosomes join amino acids together in the order specified by messenger RNA molecules. Ribosomes are made up of two parts which are; the large subunits (which connect amino acids to create a polypeptide chain) and the small ribosomal subunits (which read the RNA).
