Microorganism Flashcards
State what an anti fungal chemical does
Treats and kills fungal infections
Explain how you’d know which antibiotic to perscribe a patient
The largest inhibition zone of the antibiotic disk
Explain what an inhibition zone is
The inhibition site is the area of cleared space by antibiotics
No bacterial growth on a antibiotic disk
State two things antibiotics could do to pathogenic bacteria
Stop the reproducing
Kill them
Name the type of microorganism that antibiotics are successful against
Bacteria
Explain why you should wash your hands often
To help kill and get rid of harmful bacteria and to stop spreading them
State several ways human spread illness
Breathing infected air/coughing
Touching infected surfaces
Touch
Name a couple pathogenic microorganisms and the disease they cause
Verticillium- decays and destroys plants and animals, not humans
Simplex virus- sexually transmitted disease which has scab like symptoms
Chlamydia- sexually transmitted disease causes discharge and infertility
State what a pathogenic microorganism is
A harmful microorganism
State what a microorganism is
Microorganism are very small living things
State advantages and disadvantages of DNA testing
Advantage-
Easy to find criminals
Relation finding
Finding disease and illness
Disadvantage-
Experimental use without consent
Finding disease and illness
State what a DNA profile is
DNA profiling is the process where a specific DNA pattern is obtained from a persons dna
State what a pathogenic microorganism is
A harmful microorganism
Explain why it is good scientific practice to do the test multiple times
To get and average as results may vary
Explain why you should never open a Petri dish containing microorganism
Pathogens could escape
Name a specialised cell, it’s particular functions and the specialised adaptation which makes it good at its job
Nerve cell
Very long with many connections
Passes information through the body quickly
State the meaning of a specialised cell
Specialised cells are cells which have adapted themselves to do their job for efficiently
Name the structure sfound in plant cells
Cell membrane Cytoplasm Cell wall Vacuole Chloroplast
Name the structures found in animal cells
Cell membrane
Cytoplasm
Nucleus
State whether everyone has the same or different combinations of DNA
Different apart from identical twins
Use the words “genetic code” to explain why two organisms can have differences in one characteristic, eg one person has freckles and another does not
Your genetic code is different/has a different pattern
Describe some characteristics a human may have
Freckles, tall, short, brown eyes
State what a gene contains
DNA (genetic code)
State the meaning of a gene
A gene is a piece of DNA which gives an individual a specific characteristic
