MICROBES Flashcards
Any living creature that is small and you cant see with your eyes is known as a
MICROBE
The six most common types of microbes are
Bacteria Virus Fungus Protozoa Algae Archaea
Organisms made of one cell are known as
Unicellular organisms
Are Bacteria unicellular organisms
Yes
There are more bacteria on earth than any other life for, is this statement true
Yes
The smallest microbes are
Virus
Can a Fungus be Unicellular or multicellular
Yes
Other than plants, name a organism that uses the green pigment chlorophyll
Algae
Name the microbe that looks a lot like bacteria but behaves in a different way
Archaea
Name the microbe that can survive in extreme environments like very hot places or strong acids
Archaea
The tool which uses curved glass lenses to make things look bigger is a
Microscope
Viruses are too small to be seen using a regular microscope, we can see them using a
Electron Microscope.
A regular microscope uses a beam of light to see objects, but a electron microscope uses What ?
A beam of electrons
Scientists make bacteria grow in special plates called as
Petri Dish
A Petri Dish is filled with a nutrient filled jelly called as
Agar
Microbes that can make people sick is known as
Germs
About how many cells make up the human body
30 trillion cells
What is the basic unit of every living creature
Cell
The three parts which are common in every living cell are
Cytoplasm
DNA
Cell membrane
The jelly like substance that fills the inside of the cell is called
CYTOPLASM
The structure that holds the cell together and allows chemicals to move in and out of the cells is the
CELL MEMBRANE
The big molecule in the nucleus that tells cells how to grow and behave is the
DNA
Some bacteria have tails which help them swim and move, this tail is known as a
FLAGELLUM
Bacteria that are round or oval in shape and appear like balls are known as
COCCI
Bacteria that are shaped like rods are called
Bacilli
Bacteria that are long and twisty, and shaped like a cockscrew are known as
Spirilla
Floating in the cytoplasm are little round molecules that are able to read the DNA, these molecules are called as
RIBOSOMES
The first step in the doubling of a cell is
It copies the DNA
How much of bacteria does a person carry on himself
2 Kgs
Where are the places we can find the bacteria
Air Soil Rocks Oceans Home You
How is the bacteria in the soil helpful
The bacteria from the soil can turn nitrogen from the air into useful fertilisers for the plants. This is known as the NITROGEN CYCLE
There are more bacteria cells on our bodies than human cells, is this statement true
YES
When living organisms produce their own light, this phenomenon is known as
BIOLUMINESCENCE
Name this bioluminiscent Squid
Bobtail Squid
How does the Bobtail squid light up on its own
They have special bacteria, that make chemicals that helps the quid to light up
Name this mushroom that glows in the dark
FOXFIRE MUSHROOM
Name this fish that have glowing bacteria on their head
Female angler fish
Most of the bacteria in your body is found in the
GUT
In the small intestine long food molecules are cut into smaller size by special snippers called
Enzymes
The large molecules like OLIGOSACCHARIDES cannot be cut by enzymes in the small intestine. they are broken down by bacteria in the
Large Intestine
The bacteria in the large intestine break down large molecules like oligosaccharides into two gases, name them
Hydrogen and Methane
Name a disease that can spread very fast if drinking water is not clean
CHOLERA
What does a human suffer from when he gets CHOLERA
DIARRHOEA
Who in ENGLAND first discovered that cholera is spread through contaminated water
John Snow
The little holes in your skin are known as
FOLLICLE
The biggest organ in the body is the
SKIN
The blood in your body flows through a system of tubes called
Arteries and Veins
Is having a fever good for your body
Yes
Why is having a fever good for our bodies
During fever the temperature of the body rises and this helps to fight germs
This special type of white blood cell that engulfs germs and tears them apart is
MACROPHAGE
