Hibiscus poleni
Polen nedir?
Polen, bitkinin erkek gametini (bu nedenle
erkek DNA) dişi gamete taşıyan bir yapıdır. Polen, bu
taşınma sırasında erkek gametini çok iyi korumak zorundadır.
Polenin dış duvarı exin olarak adlandırılır.
Bu tabaka çok nadir olarak bulunan ve çok dayanıklı olan sporopollenin
denilen bir yapıdan oluşmaktadır. İç tabaka ise selülozdan
yapılmış olup, tipik bitki hücre duvarının yapısındadır.
Polen taneleri mikroskobik olup- genellikle 15-100 mikron- sıkıştırılmış
polen tozu binlerce polen tanesi içermektedir.
