Q

Are viruses living or dead?how?

A

dead, only way to reproduce is making more copies of themselves in living cells(parasitic)–) by taking over the hosts genetic machinery

Q

Describe the structure of a virus

A

composed of a core genetic material which can be DNA or RNA surrounded by a protein coat

Sometimes a membrane called an ENVELOPE may surround the virus, stolen from the surface membrane of the host cell

Q

How do fungi spread?

A

spores

17
Q

Describe the structure of the fungi

A

Multi cellular fungi-such as MUCOR are organised into
MYCELIUM- (which is made from hyphae(contain
nucelus)

18
Q

Are fungi eukaryotic or prokaryotic?

A

eukaryotic (yeast single celled)

19
Q

Name a type of fungi infection

A

Athletes foot, (a rash) causes dry and flaky skin often found in swimming pools
transmitted by touching infected, contaminated surfaces
treated with anti fungal medication

20
Q

Name a fungi infection in plants

A

Rose Black Spot disease in plants

21
Q

Are protists prokaryotic or Eukaryotic?

A

eukarotic (single-celled) they have a nucleus

22
Q

How can protists enter an organism?

A

via a vector

23
Q

What is a vector?

A

something that carries the pathagon without getting the disease itself

24
Q

Give an example of a vector

A

malaria is caused by PROTISTS which are carried by mosquitos-)when it bites a human-)infects it by transferring the protists to the blood-) malaria is fatal as it effects the red blood cells and the liver

25
Q

WHAT IS TOBACCO MOSAIC VIRUS?

A

prevents the formation of chloroplast (no photosynthesis) causes discolouring in the leaves of tobaco plants

26
Q

What does the influenza virus cause?

A

The flu

27
Q

What does HIV cause?(HUMAN IMMUNODEFICIENCY VIRUS)

A

eventually causes aids

28
Q

Are protocists unicelllar?

A

both multi (seaweeds) and uni cellular(algae/amoeba/Chlorella)

29
Q

What are protoctists also referred to as?

A

The dusbin kingdom

30
Q

What are Protozoa?

A

(eukaryotic)Unicellular organisms that live in water/ damp places.

31
Q

What is an example of a protozoa?

A

Amoeba(eukaryotic)

32
Q

What type of protoctists photosythesis?

A

Algae

33
Q

Describe the structure of fungi?

A

Their bodies are organised into a mycelium made from thread like structures called hyphae (contain nuclei)

34
Q

How do fungi consume food?

A

A process called saprotrophic nutrition

35
Q

What is saprotrophic nutrition?

A

A type of FEEDING in which DIGESTIVE ENZYMES are SECRETED outside the cell onto the food MATERIAL followed by ABSORPTION of PRODUCTS

36
Q

What is a pathogenic example of a protocit?

A

plasmodium (parasite) causes malaria
