What are the 2 difference between monera and protista ?

Question

Answer

The difference between monera and protista are 1. monera do not have true nucleus while protista have nuclei bound in there own nuclear membrane. 2. monera has a unicellular prokaryotic cellular organization which lack membrane bounded organelles while protista has a unicellular eukaryotic cellular organization with membrane bounded organelles.

Answer

Monera
This kingdom include all prokaryotic mycoplasma bacteria , actinomycetes and cyanobacteria or blue green algae .
They are basically unicellular prokaryotic and contain the most primitive of living froms .
protista
Kingdom protista include diatom, dinoflagellate ,slime moulds, sarcodines, cilliates, sporozoan ,etc
It include all unicellular and colonial eukaryotic. mostly they are aquatic organism forming of pankton .

Answer

Monera and Protista: Differences

Monera and Protista are two separate kingdoms in the classification of organisms. Although they have some similarities, there are several key differences that set them apart. Below are two prominent differences between Monera and Protista:

1. Cellular Structure and Organization:
- Monera: Organisms in the Monera kingdom are characterized by their simple cellular structure. They are unicellular and lack a true nucleus, membrane-bound organelles, and complex internal structures. Monera includes bacteria and cyanobacteria (also known as blue-green algae). These organisms are prokaryotes, meaning their genetic material is not enclosed within a nucleus. Instead, their DNA floats freely in the cytoplasm. Monera organisms also possess a cell wall made of peptidoglycan, which provides structural support and protection.

- Protista: Protista, on the other hand, comprises a diverse group of organisms that exhibit varying levels of cellular complexity. They can be unicellular, colonial, or multicellular. Protists are eukaryotes, meaning they have a true nucleus enclosed within a nuclear membrane. They also possess membrane-bound organelles, such as mitochondria and endoplasmic reticulum. Protists include organisms like amoeba, paramecium, and algae. Algae, a type of protist, can be unicellular, colonial, or multicellular and have cell walls composed of cellulose or other materials.

2. Mode of Nutrition:
- Monera: Most organisms in the Monera kingdom are heterotrophic, meaning they obtain their nutrients by absorbing organic substances from the environment or other organisms. They may be saprophytic, decomposing dead organic matter, or parasitic, deriving nutrients from a host organism. Some monera, however, are autotrophic, capable of synthesizing their own food through photosynthesis. Cyanobacteria, for example, possess pigments that allow them to convert sunlight into energy.

- Protista: Protists exhibit a wide range of nutritional modes. Some are autotrophic, using photosynthesis to produce their own food. For instance, algae, a type of protist, contain chloroplasts that enable them to convert sunlight into energy. Others are heterotrophic, feeding on organic matter or other organisms. For example, amoebas are heterotrophic protists that engulf food particles by phagocytosis. Additionally, some protists can be mixotrophic, meaning they can switch between autotrophic and heterotrophic modes of nutrition depending on environmental conditions.

In summary, Monera and Protista differ primarily in their cellular structure and organization, as well as their mode of nutrition. Monera consists of prokaryotic organisms with simple cellular structures and can be either heterotrophic or autotrophic. Protista, on the other hand, includes eukaryotic organisms with varying levels of cellular complexity, and they exhibit diverse nutritional modes, including autotrophic, heterotrophic, and mixotrophic.
