Membranebound organelles are absent in (a) Saccharomyces (b) Streptococcus (c) Chlamydomonas (d) Plasmodium.
Option B Streptococcus is a bacteria which is included under Kingdom Monera. Monerans have prokaryotic cell organisation in which membrane bound organelles like mitochondria, E.R., Golgi bodies, etc. are absent. All the other three i.e., Saccharomyces (a fungus) Chlamydomonas (an algae) and Plasmodium (a protozoan protist) are eukaryotes containing true membrane bound organelles.
