Don't spam ‼️​

Answer 1

1. Monera kingdom includes prokaryotic oraganism..

2. Organisms of Monera do not contain bound organells..

3. Organisms of Monera has lack nuclear envelop..

4. Organisms of Monera may be autotropic or heterotropic...mostly of the membrane are heterotropic..

.

5. They can divided into 3 parts on their basis of heterotropic mode of nutrition...

6. Organism of Monera does not contain chlorophyll..

7. Kingdom Monera includes --bacteria, Virus, and Mycoplasma...etc..

8. Mycoplasma which is the smallest living cell, without cell wall also the part of Monera kingdom...

Answer 2

Answer:

What is Monera Kingdom?

The Monera Kingdom consists of organisms that do not consist of a nucleus, e.g prokaryotic cells (bacteria and archaea).

It consists of all bacteria. Bacteria are one-celled organisms that are made of very simple components. They often lack a nucleus and a cell membrane. ... This means that a single cell copies its DNA and then divides into two identical cells.

Examples:

• Heliobacter pylori.

• E. coli.

Explanation:

Kingdom Monera Characteristics:

• They are primitive organisms.

• All organisms of the kingdom are prokaryotes.

• They are present in both living and non-living environment.

• They can survive in harsh and extreme climatic conditions like in hot springs, acidic soils etc....

Species of Kingdom Monera:

• Cyanophyta. This phylum of bacteria contains organisms that were once known as “blue-green algae.”

• Proteobacteria.

• Spirochaetes.

• Classification.

• Eubacteriophyta. Eubacteriophyta are the true gram-positive bacteria.

Salient features of Kingdom Monera:

• They are primitive organisms.

• All organisms of the kingdom are prokaryotes.

• They are present in both living and non-living environment.

• They can survive in harsh and extreme climatic conditions like in hot springs, acidic soils etc.

• They are unicellular organisms.

• Monera kingdom includes prokaryotic organisms.
• Organisms of Monera do not contain membrane bound organelles.

• Organisms of Monera lack nuclear envelope & DNA without histone such DNA known as Nucleoid or Genome.

• Organisms of Monera may be autotrophic or heterotrophic but most of the members are heterotrophic.

• Parasitic: those organism which fed on other living organism.

• saprophytic: those organism which fed on dead or decaying organic matter by decomposing it.

• Membrane bound nucleus is absent.

• DNA is in double stranded form, suspended in the cytoplasm of the organism,referred as nucleoid.

• A rigid cell wall is present.

• Membrane bound cellular organelles like mitochondria are absent.

• Habitat - Monerans are found everywhere in hot springs, under ice, in deep ocean floor, in deserts and on or inside the body of plants and animals.

• Nutrition - autotrophs - can prepare their own food, heterotrophs - depend on others for food, saprophytes - feed on dead and decaying matter, parasitic - live on other host cells for survival and cause, symbiotic - in mutual relation with other organisms, commensalism - it is where one organism is benefited and the other is not affected, mutualism - where both the organisms are benefited.
