Question

1a. Like mitochondria, what is/are examples of “ex-microbe” organelles?
   apicoplasts
   bacteriocytes
   kinetoplasts
   a AND b
   a AND c

1b. Buchnera and aphids share a nutritional symbiosis where they provide each other with
   nucleic acids
   amino acids
   lactic acids
   electrons

1c. The symbiosis between Buchnera and their host has resulted in the shrinking of the Buchnera genome, losing genes encoding for specific
   lac operons
   feeder pathways
   stress response pathways
   biosynthetic pathways

Explanation / Answer

(1) a and b

apicoplast is a non parasytic plastid and a product of secondary endosymbiosis. Bacteriocytes are a type of endosymbiotic bacteria reside in Aphids.

(2) amino acids
Buchnera benefit Aphids mainly by producing essential amino acids

(3) biosynthetic pathways

Due to symbiotic association and reduction in genome Buchnera have lost genes necessary to produce many nutrients.
