b. Write the characteristics of viruses.
c. Explain the nutrition in fungi.
d. Which living organisms are included in
the kingdom monera ?
Answers
Answer:
hello ,
firstly , virus are neither living nor dead . They behave differently in different conditions.
viruses contain a nucleic acid whether DNA or RNA and a protein coat surrounding it.
they us the machinery of the host to replicate.
viruses can be crystallised.
they lack metabolism and respiration .
they are not included in any kingdom of classification.
members of kingdom fungi do not contain chlorophyll and hence they can not prepare their own food and are dependent on some other sources for food
.These type of nutrition is called heterotrophic nutrition .
soul members or the main members of kingdom monera are bacterias
eg : lactobacillus
mycobacterium tuberculosis
Heliobacter pylori
E. coli
Hay bacillus
Salmonella typhi
Staphylococcus aureus
Explanation:
Answer:
b. The various characteristics of viruses are:
- They are smaller and simpler than bacteria.
- They are ultra microscopic and visible only under electron microscope.
- They are considered to be on the boundary line of living and non-living things.
- They are obligate parasites and cannot live on their own.
- They cannot multiply on their own. They require living machinery to multiply.
- Viruses consist of genetic materials (DNA or RNA) surrounded by a protective coat of protein (capsid).
- Viruses are responsible for causing many dreadful diseases in plants, animals, and humans.
c. The mode of nutrition in fungi is saprotropic and they are called saprophytes. It is a mode of nutrition in which an organism obtains its nutrients from the decaying organic matter.
d. Organisms with following characteristics are inlcuded under the kingdom monera:
- Absence of nucleus and membrane-bound organelles
- Presence or absence of cell wall
- Can be either autotrophic or heterotrophic
- Are all unicellular and include mainly bacteria and blue green algae
• Examples include bacteria and blue green algae.
