Asexual Reproduction
Reproduction that produces genetically identical offspring from one parent

Bacteria
Microorganisms that are singled celled and lack a nuclear membrane. There are many different types of bacteria.
6 of 42
Binary Fission
The process by which bacteria reproduce
7 of 42
Budding
A process of asexual reproduction that involves a bud forming

Cell Membrane
The semi-permeable membrane forming the outer boundary.
9 of 42
Cell Wall
An outer layer of a cell that is ridged and in plants and most algae it is made of cellulose. It is not found in animals.
10 of 42
Competion
An outer layer of a cell that is ridged and in plants and most algae it is made of cellulose. It is not found in animals.
11 of 42
Competion
An ineraction that occurs between individuals or populations. This may be over environmental factors that they share or that overlap, e.g. food, light or shelter.
12 of 42
Culture
a group of microoganisms grown for a specific use, e.g. group of bacteria grown on nutrient agar under specific conditions.
13 of 42
Cytoplasm
A jelly like substance found in a cell. It is a matrix in which the cells organelles are suspened.
14 of 42
Diffusion
A natural process in which particles move from a high concentration to a low concentration until an even distribuation of particles occurs.
15 of 42
Enzymes
A protein that is a biological catalyst in cellular reactions.
16 of 42
Excreted
The process of an organism getting rid of its wastes.
17 of 42
Extracellular
Outside the cell.
18 of 42
Flagellum
Long thread-like structures, attached to bacteria which allow them to move.
19 of 42
Fungi
A group of miroorganisms that can exist as either uni-cellular or multi-cellular. Yeasts and moulds.
20 of 42
Genetic Material
May be in the form of DNA or RNA. Contains information for the cell to make proteins.
21 of 42
Growth Curve
The rate at which a colony of miroorganisms’ increases in number.
22 of 42
Host
A cell or organism that provides food, shelter or in the case of viruses; essential process it requires for replication.
23 of 42
Hypae
A filament in fungi that secretes digestive enzymes.
24 of 42
Mirobe/Miroorganism
An organism that can only be seen with the use of a miroscope.
25 of 42
Moulds
Type of fungi.
26 of 42
Multicellular
Many cells working together to form an organism.
27 of 42
Mycelium
A mass of hypae that form the body of a fungus.
28 of 42
Nutrient Agar
A jelly like substance that contains nutrients for growing miroorganisms
29 of 42
Nutrients
Any substance that a living organism requries for nutrient. Either for energy or structural growth.
30 of 42
Pathogens
An organism that causes disease.
31 of 42
Reproductive Hypae
Hypae that contain sporangium full of spores.
32 of 42
Respiration
A cellular process that uses oxygen and water and glucose to form energy and carbon dioxide.
33 of 42
Reproduce
To produce offspring.
34 of 42
Secrete
The movement of a substance produced by the organism to outside the cell.
35 of 42
Slime Capsule
A layer of slime that is found on the outer most part of some organisms.
36 of 42
Sporangium
A reproductive structure in fungi that produces spores.
37 of 42
Spores
Is a reproductive structure cell. It can develop into an individual when certain conditions are present.
38 of 42
Ubiquitous
Is found everywhere.
39 of 42
Unicellular organisms
Organisms that only have one cell.
40 of 42
Viruses
A very small particle that is inert outsidde a host cell. When it reaches a host cell it is able to replicate as it does it destroys the host cell. They are pathogens.
41 of 42
Yeasts
A group of unicellular organisms that are classfied as Fungi.
