Classification of living organisms
What is classification and why is it important?
Classification means the organization of items into groups based upon similarities and differences.
Living organism’s classification is needed for the convenient study of it.
It helps to know the origin and evolution of organisms.

What is a virus?
Organisms at the edge of living and nonliving.
Which living organisms are included in the kingdom monera ?
All kinds of bacteria.
When fungus is formed on bread, what is it called?

State one demerit of Whittekar's classification.
It cannot classify virus which is at the edge of living and non-living organisms.
Name two pseudopodia and why is it used?
1)Hair like Cilia
2)Whip like Flagella
Protista kingdom organisms use it for locomotion.
What are the organisms depending on decaying organic matters called? What are the two methods by which they reproduce?
Saprotrophs.
1) Cell Division
2) Budding
Virus is a long molecule of ________ or _________ covered by a ________ coat.
DNA, RNA, protein
What is the criteria for Whittekar's classification?
1. Complexity of cell structures
2. Complexity of organisms
3. Mode of nutrition
4. Lifestyle
5. Phylogenetic Relations
Cell wall of fungi is made up of ________.
Chitin.
When you think of the most deadly creature in the world, your instinct is probably to imagine a crocodile, or some massive animal with big claws or huge teeth. In fact, the most deadly disease causing animal is mosquito. What is the name of the kingdom it belongs to and what is the name of microbe?
Protozoa.
Plasmodium Vivax (Female Anopheles)
Match the following :
A B
Fungi Chlorella
Protozoa Bacteriophage
Virus Candida
Algae Amoeba
Bacteria Prokaryotic
Fungi - Candida
Protozoa - Amoeba
Virus - Bacteriophage
Algae - Chlorella
Bacteria - Prokaryotic
Use Whittaker method to classify bacteria, protozoa, fungi, algae, prokaryotic and eukaryotic microbes.
1.Kingdom Monera which included prokaryotic organisms like Bacteria and prokaryotic microbes.
2.Kingdom Protista which included eukaryotic organisms like Protozoans and eukaryotic microbes.
3.Kingdom Fungi includes eukaryotes like Fungi.
4.Kingdom Plantae includes eukaryotes like Algae.
5.Kingdom Animalia includes eukaryotic animals.
Why is refrigeration important in the food industry?
The food industry spends millions of dollars every year on refrigeration and it is very important that they know what temperature they need to stop mold from growing. Moldy food must be thrown away and this costs restaurants and manufacturers a lot of money.
I am green, but don’t have organs. If you ever visit the beach you’d find these slimy plants on the beach, do you know what are they? They can exist on their own or they can grow on the surfaces of other organisms, in the soil or on rocks. These organisms are very important because they make much of Earth’s oxygen, which humans and other animals need to breathe. Are they autotrophs or hetrotrophs? (There is a follow up question as well)
Algae. Autotrophs. Chloroplast.
How do virus survive and reproduce? What is the importance of RNA or DNA?
Viruses survive only in living plant or animal cells and produce their own proteins with help of host cell and create their numerous replica. Then they destroy the host cell and become free.
It tells you how the organisms evolved and it passes its traits to the offsprings.
