Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 1

The diatomaceous earth is used to insulate boilers and steam pipes because:-

Detailed Solution for Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 1

Cells of diatoms are surrounded by the cell wall, deposited with silica called as frustules which are composed of two overlapping halves (the epitheca and the hypotheca). Shells of diatoms are highly resistant to decomposition due to the presence of silica and are deposited in ocean beds leading to the formation of the diatomaceous earth. This is used as filters because its silica content makes it chemically inactive and uncompressible during insulation.

Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 3

Which of the following is the only group of organisms capable of using inorganic compounds as source of energy:

Detailed Solution for Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 3
  • On the basis of their energy source, organisms are classified as organotrophic and lithotrophs.
  • Most prokaryotes and all non-phototrophic eukaryotes use organic compounds as their energy source and thus, are referred to as organotrophs.
  • They oxidise organic compounds during cellular respiration and the produced oxygen as a byproduct. But some Cyanobacteria and Archaea use inorganic compounds as an electron donor in electron transport chain and are referred to as lithotrophs, none of the eukaryotes falls in this category.
  • Virus act as non-living outside the cell. It becomes active when it enters the host cell and derives the cellular protein from the host.
Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 4

“Perfect stage” of a fungus means

Detailed Solution for Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 4

A phase in the life cycle of certain fungi in which sexual spores are formed, as the asci in the sexual stage of the ascomycetes it is referred to as the perfect stage.

Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 5

Asexual spores in Ascomycetes are called as _______

Detailed Solution for Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 5

Asexual spores in Ascomycetes are called Conidia and are produced exogenously by conidiocarps. Sexual spores in Ascomycetes are called Ascospores and are produced endogenously in asci present inside Ascocarps.

Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 6

Phycomycetes are also called as ______

Detailed Solution for Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 6

Phycomycetes are also called as Conjugation fungi. Because, phycomycetes can reproduce using dissimilar gametes i.e. anisogamous fertilization can take place and hence came the name conjugation fungi.

Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 7

Contractile vacuole is present in

Detailed Solution for Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 7

Protozoa living in fresh water are subjected to a hypotonic environment. Water flows across their plasma membrane since their cytosol is always hypertonic to the environment. Many wall-less protozoa have an organelle, the contractile vacuole complex (CVC), that collects and expels excess water.

Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 8

Which kingdom incorporates phytoplanktons and zooplanktons

Detailed Solution for Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 8

Zooplankton belong to the KingdomProtista. This kingdom contains many unicellular organisms which do not fit into any other kingdom. Protists are classified as any organism which is not an animal, plant, or fungus. Although this kingdom contains mostly unicellular organisms, it can also contain some multicellular organisms which include algae. Members of this kingdom can be either heterotrophic or autotrophic.

Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 9

Karyogamy means ______

Detailed Solution for Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 9

The word “karyo” means nucleus and “gamy” means fusion. Therefore the word “karyogamy” refers to the fusion of nuclei. In the sexual cycle of fungus to form spores, plasmogamy is followed by karyogamy and then by meiosis.

Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 10

Which of the following bacteria lack a cell wall and are therefore resistant to penicillin?

Detailed Solution for Test: Biological Classification -Kingdom Monera Protista Fungi (April 3) - Question 10

Mycoplasma are a mollicute genus of bacteria that lack a cell wall around their cell membranes. This characteristic makes them naturally resistant to many common antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis. They can be parasitic or saprotrophic.
