Can protocists move?
Yes
How do protocists obtain nutrition?
Outside their body
Do protocists have chloroplasts?
Some do
Give 3 examples of protocists
AMOEBA
CHLORELLA
PLASMODIUM (pathogen causes malaria)
do amoeba and chlorella have features of plants or animals?
AMOEBA- animal
CHLORELLA- plant
Which fungi are unicellular?
Yeasts
How do fungi obtain nutrition?
Saprotrophic nutrition
What is saprotrophic nutrition?
When digestive enzymes are released OUTSIDE THE BODY into food material to break it down. Then the new molecules are reabsorbed
Are fungi multicellular or unicellular?
Both
Are fungi prokaryotes or eukaryotes?
Eukaryotes
Do fungi have chloroplasts?
No
How are fungi arranged?
In a mycelium structure made from thread like hyphae which contain many NUCELEI
How do fungi store carbohydrate?
Glycogen
What is a fungi’s cell wall made of?
Chitin
Give 2 examples of fungi
Yeast
Mucor
Can fungi be pathogens?
Yes
Can protocists be pathogens?
Yes
Are plants and animals multicellular or unicellular?
Multicellular
Are plants and animals prokaryotes or eukaryotes?
Eukaryotes
How do plants and animals store carbohydrate?
Plants: starch
Animals: glycogen
Are Bacteria prokaryotes or eukaryotes?
Prokaryotes
Can Bacteria be pathogens?
Yes
Are Bacteria multicellular or unicellular?
Unicellular
Name the 6 features of a Bacteria
Cell wall Cell membrane Cytoplasm Plasmids Circular chromosome of dna Slime capsule
Do Bacteria have chloroplasts?
Some do
How do Bacteria obtain nutrition?
Feeding off of other living or dead organisms
Give 2 examples of bacteria and explain what they are
LACTOBACILLUS BULGARICUS: rod shaped bacteria used to make yoghurt from milk.
PNEUMOCOCCUS: spherical bacterium that is a pathogen for pneumonia
What can be a pathogen?
Fungi
Bacteria
Protocists
Viruses
Order these biggest to smallest:
Virus, bacteria , animal cells
Animal cell
Bacteria
Virus
What’s the difference between prokaryotes and eukaryotes
Eukaryotes have a membrane bound nucleus, but prokaryotes don’t
All viruses are….?
Pathogens
Give 3 examples of viruses and explain what they are
INFLUENZA: causes flu
HIV: causes AIDS
TOBACCO MOSAIC: destroys chloroplasts in a plant and stops photosynthesis. Causes discolouration in leaves.
Are viruses living or not?
Non living
Viruses are parasitic, what does this mean?
Use living organisms to reproduce
Can viruses reproduce in non living cells?
No but can survive outside a host for a long time
Name the features of a virus?
No cellular structure
Protein coat
1 type of nucleic acid (dna or rna)
Do viruses have a nucleus?
No
How do viruses reproduce?
By infecting host cells and replicating themselves to form their DNA into virus particles. Once the host cells burst, the virus is spread.
Do protocists have a nucleus?
Yes
Does bacteria have a nucleus?
No
How do Bacteria store dna
Circular chromosome of dna
Plasmids
What are the plasmids in bacteria?
Closed circles of dna in the cytoplasm that can move from one bacterium to the other.
Do Bacteria have cell walls?
Yes
Which pathogen causes malaria?
Plasmodium
Do protocists have a nucleus?
Yes
Do protocists have cell walls?
Some do
