Fungi, Protoctists and virus
Fungi
Most fungi are microscopic, consisting of thread like structures less than 10 µm in diameter named hyphae.
fungi are living thing that do not have chlorophyll
Fungi are eukaryotic organisms that include microorganisms such as yeasts, moulds and mushrooms.
any member of a kingdom of organisms (Fungi) that lack chlorophyll, leaves, true stems, and roots, reproduce by spores, and live as saprotrophs or parasites.
Characteristhics Of Fungi
Fungi are eukaryotic, non-vascular, non-motile and heterotrophic organisms.
They may be unicellular or filamentous.
They reproduce by means of spores.
Fungi exhibit the phenomenon of alternation of generation.
Fungi lack chlorophyll and hence cannot perform photosynthesis.
Fungi are one of the most important groups of organisms on the planet as they play a vital role in the biosphere and have great economic importance on account of both their benefits and harmful effects.
Virus
WHAT IS A VIRUS?
A virus is an infectious microbe consisting of a genetic material (either DNA or RNA) surrounded by a protein coat.
Viruses are not considered as living things because they do not have the 7 characteristics of living things.
Viruses take over a host cell’s metabolic pathways in order to make multiple copies of themselves.
Virus Structure
GENERIC MATERIAL (DNA / RNA)
Protein Coat
Envelope
Example of Viruses
Human Immunodeficiency Virus (HIV)
Influenza
Corona Virus
Protoctist
What are Protoctist ?
Protoctists are any member of a group of diverse eukaryotes. They are predominantly unicelullar. In other words, protists are the category of eukaryotes that is not a true animal, plant, or fungi.
Protists may share certain characteristics with animal, plant, and fungi cells.
Common protoctists include
Cyanidioschyzon merolae
(red algae),
Chlamydomonas reinhardtii
(green algae),
Thalassiosira pseudonana
(marine diatom), and protozoans such as euglenoids, dinoflagellates, amoeboids, radiolarians, and volvox
Protoctist features
Protists are incredibly diverse. Most are unicelullar but some are multicelullar (but never multitissue). Protists are also predominantly between 5 μm to 2 or 3 mm. But some species like the brown algal protist can reach up to 60 metres.
Since protist must survive with 1 cell, they have very complex cell structure
Protists have means of locomotion in the form of flagellates, cillia, and pseudopodia
Protoctist classification
Protoctists are classified into 3 categories, which are protozoa (animal-like), algae (plant-like), and molds (fungi-like).
Questions
What are protoctists ?
Protoctists are eukaryotic organisms, usually uniselullar, that are not true animals, fungi, or plants
Are protoctists able to do photosynthesis ?
Some protoctists, particularly algaes, are able to do photosynthesis, since they have chloroplasts. Other protoctists however, could not do photosynthesis.
How do protoctists move ?
Protoctists move by using their flagellattes, cillia, and pseudopodia.
Why are viruses not considered living beings ?
Viruses do not have the 7 characteristics of living things. It cannot move, conduct respiration, respond to stimulus, grow, reproduce on its own, excrete, and it does not require nutrients.
What are some examples of viruses ?
Some common examples of viruses are influenza viruses, varicella zoster virus (chickenpox), HIV (AIDS), SARS CoV-2 (COVID-19), etc.
How do viruses make multiple copies of themselves ?
Viruses insert their DNA into the nucleus of another organism. The organism will then synthesize copies of the virus and release it from the cell.
What is the difference between fungi and plants ?
The main difference between fungi and plants is that fungi are heterotrophs while plants are autotrophs. This means that plants could produce their own food while fungi could not.
What are the characteristics of fungi ?
Fungi are eukaryotic, non-motile, non-vascular, heterotrophic, and reproduce with spores.
What are the uses of fungi for humans ?
Humans use fungi organisms in the production of bread, alcohol, some types of cheeses, antibiotics (penicillin), and they could be genetically modified to produce insulin and other substances
What are the role of fungi in the ecosystem ?
Fungi are major decomposers in terrestrial and some aquatic ecosystems.
