Microorganisms are tiny organisms which can be seen with the naked eyes.
-
True
-
False
Correct Answer
A. FalseExplanation
Microorganisms are not visible to the naked eye as they are extremely small in size. They can only be seen under a microscope. Therefore, the statement that microorganisms can be seen with the naked eye is false.Rate this question:

The viral DNA replicates using material in the host cell.
-
True
-
False
Correct Answer
A. TrueExplanation
The given statement is true because viral DNA relies on the resources and machinery present in the host cell to replicate. Once the virus enters a host cell, it takes control of the cell's machinery and uses it to produce new copies of its DNA. This process allows the virus to multiply and spread throughout the host's body. Without the host cell's materials and mechanisms, the viral DNA would not be able to replicate and the virus would not be able to survive and propagate.Rate this question:

Parasitic obtain food from living organisms.
-
True
-
False
Correct Answer
A. TrueExplanation
Parasites are organisms that rely on a host organism to obtain food and survive. They live off the nutrients and energy provided by the host, often causing harm or disease in the process. Therefore, it is true that parasites obtain food from living organisms.Rate this question:

Some bacteria synthesise food through chemosynthesis using chemical energy from oxidising chemicals such as nitrite.
-
True
-
False
Correct Answer
A. TrueExplanation
Some bacteria are capable of synthesizing food through chemosynthesis, a process that involves using chemical energy from oxidizing chemicals like nitrite. This allows them to convert inorganic compounds into organic compounds, serving as a source of energy for their survival. Therefore, the statement is true.Rate this question:

Dark and damp places include decaying matter and bodies of living organisms.
-
True
-
False
Correct Answer
A. TrueExplanation
Dark and damp places are conducive environments for the growth and accumulation of decaying matter and bodies of living organisms. The lack of light and moisture in these places creates conditions that promote the decomposition and decay of organic material, providing a suitable habitat for various organisms. This makes the statement "Dark and damp places include decaying matter and bodies of living organisms" true.Rate this question:

Viruses do not have cytoplasm, plasma membrane or nucleus.
-
True
-
False
Correct Answer
A. TrueExplanation
Viruses are considered to be acellular entities because they lack the basic components of a cell, such as cytoplasm, plasma membrane, and nucleus. Unlike cells, viruses cannot carry out metabolic processes or reproduce on their own. Instead, they rely on infecting host cells and hijacking their cellular machinery to replicate. Therefore, the statement that viruses do not have cytoplasm, plasma membrane, or nucleus is true.Rate this question:

Saprophytic feed on living organisms, for example Plasmodium feeds on cells in the human body.
-
True
-
False
Correct Answer
A. FalseExplanation
The statement is false because saprophytic organisms do not feed on living organisms. They obtain their nutrition by decomposing dead organic matter. Plasmodium, on the other hand, is a parasitic organism that feeds on cells in the human body, not a saprophyte.Rate this question:

Some fungi are multicelluter microorganisms such as yeast.
-
True
-
False
Correct Answer
A. FalseExplanation
Fungi are not multicellular microorganisms, but rather they can be either multicellular or unicellular. Yeast, which is a type of fungi, is unicellular. Therefore, the statement "Some fungi are multicellular microorganisms such as yeast" is false.Rate this question:

Algae have chloroplast, nucleus, cytoplasm and cilia.
-
True
-
False
Correct Answer
A. FalseExplanation
Algae are photosynthetic organisms that contain chloroplasts, which allow them to convert sunlight into energy. They also have a nucleus, which contains their genetic material, and cytoplasm, which is the fluid-filled region inside the cell. However, algae do not have cilia, which are hair-like structures used for movement. Therefore, the statement that algae have cilia is false.Rate this question:
