BIOLOGY 3 Lecture Notes - Lecture 17: Mitosis, Meiosis, Cordyceps
Document Summary
Mattake, or matsutake, mushroom is the most expensive mushroom in the world today. Unikont = a single cilium per cell. Bikont = two cilia (or multiples of two) per cell. Two of the six major protist clades (amoebozoa and opisthokonts) are grouped together as unikonts (one cilium). The other four clades are bikonts (two cilia per cell). Two of the major kingdoms of traditional taxonomic schemes (fungi & Animals) are actually contained within the monophyletic protistan group, Opisthokonts = fungi + nucleariids + choanoflagellates + Opisthokonts- have flattened mitochondrial cristae and single posterior cilia. Shape of an animal sperm cell is a good way to remember the basic shape of an opisthokont. It is also the same basic shape as the motile form of a chytrid. The idea that all fungi and animals share a common ancestor is a relatively recent one but it is exceedingly well supported by morphological, biochemical, and genetic evidence.
