Scope of Microbiology Flashcards
What are the properties of ALL cells?
Compartmentalization and metabolism, growth, and evolution.
The cell is a/an (blank) system.
Open
Chemical from the environment are turned into (blank) under the genetic direction of pre-existing cells.
New cells
(blank) show the evolutionary relationships between cells.
Phylogenetic trees
We measure growth in terms of (blank) in microbiology.
Population
True or false. All cells are capable of self-propulsion.
False
Only some are capable of motility.
What is the ability of cell to create specialized structures to help them survive?
Differentiation
What is an example of differentiation?
Creation of spores
Many cells communicate by creating (blank).
Chemicals
True or false. Cells can exchange genetic information with cells of the same species only.
False.
They can also exchange with different species.
One of the first forms of life.
Anoxygenic phototrophic bacteria
Purple bacteria
Anoxygenic phototrophic bacteria slowly turned into (blank).
Cyanobacteria
(blank)% of the Earth’s history was exclusively microbial.
80
Penicillin was derived from (blank) which is a (blank).
Penicillin notatum, fungi
Botox is produced by the bacteria (blank).
Clostridium botulinum
How does botox work?
Blocks chemical signals from nerves → relaxed muscles in the areas where wrinkles are common → reducing wrinkles
Examples of bioremediation.
Degrading oil organisms for oil spill, plastic eating fungi
Advantage of Bacillus thuringiensis (Bt) corn.
Resistant to pests/fungi
An alternative to fuel.
Methanogenic gas
Nail fungal infection is called (blank).
Onychomycosis
Fungi is Tinea unguium
King Tut’s Curse
A lot of people died after opening his tomb.
Bacteria in anthrax.
Bacillus anthracis
Some bacteria are (blank)ic while some are (blank)ic.
Photosynthetic, chemoorganotrophic
True or false. All algae are single-celled.
False.
Some are single-celled, some are multicellular.
Algae can be (blank)ic or (blank)ic.
Photosynthetic, parasynthetic
True or false. Algae are static organisms.
True.
What does Ophiocordyceps unilateralis do?
They create zombie ants, controlling their behavior by taking control of their nervous system, making them move to higher places with higher humidity where they can spread their spores.
True or false. Pinocytosis occurs in protozoans.
False. Phagocytosis occurs in protozoans.
Phagocytosis is the process of engulfing and feeding on other organisms
True or false. Protozoans are single-celled organisms.
True.
True or false. Viruses have nucleus.
True.
Viruses are either (blank) or (blank).
Enveloped, naked
How do viruses thrive?
They require a host to replicate and survive.
