short ans. type qust. write down the identifying traits of Monerans.?
Answers
Explanation:
Monera (Monos – single) includes prokaryotes and shows the following characters:
They are typically unicellular organisms (but one group is mycelial). The genetic material in these organisms is the naked circular DNA. A nuclear envelope is absent. Both, ribosomes and simple chromatophores, are the only subcellular organelles in the cytoplasm.
Sap vacuoles do not occur. Instead, gas vacuole may be present.
The predominant mode of nutrition is absorptive but some groups are photosynthetic (holophytic) and chemosynthetic.
The organisms are non-motile or move by the beating of simple flagella or by gliding.
Answer:
Monerans is a biological kingdom that is made up of prokaryotes. As such they composed of single-celled organisms that lack a true nucleus.
• The Monerans are unicellular organisms.
• They contain 70S ribosomes
• The DNA is naked and is not bound by a nuclear membrane.
• It lacks organelles like mitochondria, lysosomes, plastids, Golgi bodies, endoplasmic reticulum, centro-some, etc.
• They reproduce asexually by binary fission.
