SCIPAD - Microorganisms & The Environment Glossary Flashcards
CB 1.1
Life processes
Characteristics of a living organism, represented by MRSCGREN
respiration
A chemical reaction that occurs in the mitochondria which releases energy from food.
aerobic
Using oxygen.
anaerobic
Not using oxygen.
excretion
Getting rid of waste produces made by cells.
growth
Creating more cells by mitosis.
Reproduction
Making new individuals.
nutrition
Taking in food to get substances for growth and energy for cell processes.
Taio
Earth, natural world, environment
mauri
Spark or life force - in this context we will use mauri as an expression of the health / balanced function of an ecosystem.
Abiotic factor
Abiotic factors in an ecosystem are non-living elements of the environment that influence the way organisms and ecosystems function.
Biotic factor
Biotic factors are the living parts of an ecosystem
eukaryote
A eukaryote is an organism whose cells have a nucleus and other membrane-bound organelles
prokaryote
A prokaryote is a single-celled organism that lacks a nucleus and other membrane-bound organelles
organelle
An organelle is a part of a cell that has a specific function and is usually enclosed within its own membrane. Organelles are found only in eukaryotic cells, not in prokaryotic cells like bacteria.
Mitochondrion
an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occurs
chloroplast
A chloroplast is a cell organelle that produces energy through photosynthesis.
nucleus
a dense organelle present in most eukaryotic cells, containing the genetic material.
ribosome
A ribosome is a cellular structure that performs protein synthesis
Cell membrane
Also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell.
Cell wall
A cell wall is an outer layer surrounding certain cells that is outside of the cell membrane. The cell wall provides strength and structural support to the cell.
Mucus capsule
Layer of sticky compounds that aid bacteria to stick to food sources.
Layer of sticky compounds that aid bacteria to stick to food sources.
hyphae
The long branching filaments of a fungus.
spore
The one-celled reproductive unit of fungi.
endospore
A rounded, inactive form that certain bacteria assume under conditions of extreme temperature, dryness, or lack of food.
fermentation
A metabolic process by which organic molecules (normally glucose) are converted into acids, gases, or alcohol in the absence of oxygen
virus
A virus is a chain of nucleic acids (DNA or RNA) often housed in a protein coat or protein envelope, a protective covering which allows the virus to survive between hosts.
unicellular
An organism made up of only one cell.
An organism made up of only one cell.
multicelluar
An organism made up of more than one cell.
antibiotic
Substances that are capable of killing and inhibiting growth of specific microorganisms, such as infectious bacteria and fungi.
pathogen
A disease-causing micro-organism.
microbe
Bacteria, unicellular fungi, viruses.
enzyme
Proteins in cells that act as a catalyst to speed up a reaction without itself being changed in the process.
