endosperm tissue of angiosperms has what ploidy level
Endosperm About 70% of angiosperm species have endosperm cells that are polyploid.[4] These are typically triploid (containing three sets of chromosomes), but can vary widely from diploid (2n) to 15n.[5]
Nasal septum The fleshy external end of the nasal septum is sometimes also called columella. The nasal septum contains bone and hyaline cartilage.[2] It is normally about 2 mm thick.[3]
