Question

Write characteristics of : (50-100 words)

1. Monera
2. Fungi
3. Protista

Answer 1

Characteristics of Monera.

1. Monera are about 1 micrometer in size and complex as living molecules.
2. The Monera cell structure is mostly unicellular and some organisms orm groups or filaments.
3. These organisms are the simplest prokaryotic cell structures.
   
4. The cell structure lacks nuclei and many other cell organelles.
5. They have a cell wall made of polysaccharides with polypeptide cross links with a chemical called peptidoglycan.
6. They lack enclosed sub-cellular organelles like mitochondria and only have ribosomes.

Characteristics of fungi

1. The non-motile cells belong to the kingdom Fungi.
2. The cell walls of these non-motile cells are made of chitin.
3. Fungi are heterotrophic organisms. The only difference between other heterotrophic animals and fungi is that fungi digest and then ingest the food. Fungi release enzymes on the body of the other living things and thrive on them.
4. Fungi lack chlorophyll, which is a pigment used by plants to produce food. Most types of fungi are saprophytic in nature, which implies that they feed on dead and decaying matter.
5. There is no embryonic stage for fungi. A fungus develops from spores, and are both sexual and asexual.
6. Though most of the fungi are single cellular, most of the fungi species grow as multicellular filaments called hyphae. The hyphae form a mass called the mycelium.

Kingdom protista is one among 5 kingdom classification.
Some of the characteristic features of protists are:

1. most of the organisms in kingdom protista are unicellular..but biology has exception s to everything.. multicellular organisms like algaes are also included in this Kingdom.
2. They are eukaryotes ie, they have well structured and membrane bound nucleus and organelles
3. they mainly move using they locomotive structure called flagella or cilia.
4. they are aquatic in nature ..they may live both on fresh water or marine water.
5. modenof nutrition may be heterotrophic or autotrophic.
