Protista Flashcards
Everything
What three groups does protists consist of
Plant like protists which are autotrophic as they contain chlorophyll and produce their own food through photosynthesis can be unicellular or multicellular
Animal like protists(protozoa) mostly heterotrophic or parasitic and move by using pseudopodia,cilia or flagella
Fungus like protists are decomposers which make them heterotrophs,digest food by releasing digestive enzymes into organic matter and absorbing the nutrients
How do protists reproduce
Sexually through binary fission I’m favourable conditions
I’m unfavourable conditions sexual reproduction can occur and a resistant stopped is formed
What is the life cycle of malaria
Female mosquitoes bites human and sucks blood containing plasmodia parasites
Plasmodia reproduces sexually in female mosquitoes
Female mosquitoes bites a human and transfers the paslmodia parasite into blood
Plasmodia travels to the liver and enters liver cells
Plasmodia reproduces asexually I’m cells
Plasmodia hurts out ofnluver cells and enters bloodstream
Once in blood plasmodia enters the red blood cells and reproduces asexually again and burts into into bloodstream again
Prevention and control of malaria
Using insect repellent and insecticide
Sleeping under mosquitoes nets
Draining stagnant water
Introduce fish that eats mosquito eggs
Treatment of malaria
Modern medicine- anti malarial drugs such as quinine,chloroquine and merpacrine,they drugs interrupts the parasites life cycle
In severe cases blood transfusion will be necessary
Traditional-herb sweet wormwood-stops multiplication of parasite in liver and blood cells
What are the symptoms of malaria
Take a two weeks for flu like symptoms to show
Experience shiverings cause by when parasites bursts out of cells
High fever(depending on stage of parasite)
Sweating (depending on stage of parasite)
Convulsions may occur which can lead to coma and eventually death
Headaches and vomiting
Liver and spleen become infected which leads to jaundice
Continuous rupture of red blood cells lead to anaemia
Blockage may occur in blood vessels of major organs e.g kidneys and brain with may lead to death
Prevention and control
Using insect repellents and insecticide
Sleeping under mosquitoes nets
Draining stagnant water
Introduce fish that eats mosquito eggs
Where is malaria common
Tropical and subtropical areas of Africa,Central and South America and Asia
What causes malaria
Four different protists species called plasmodia
What is plasmodia
A single called protists that occurs in parasitic form only
What does plasmodia cause
Disease by destroying the red blood cells of host
Where does the plasmodia parasite compete it’s cycle
In humans and female anopheles mosquitoes
How does plasmodia reproduce
Both sexually and asexually by producing spores
