Malaria and fungi reproduction Flashcards
Revise
What is a protist
An animal or insect that spreads disease or illness like a mosquito
What is plasmodium
Parasitic protozoans that cause malaria
What is the process of plasmodium
-Protist infects the person and injects them with thousands of Sporeozoites
-The liver is then infected
-the sporeozoites begin to multiply by mitosis
-The liver ruptures amd merozoites are released into the blood where they continue to reproduce asexually
-Spread to other protists if they consume your blood while the infected experiences fever and possibly dies
Symptoms of plasmodium
-Fever
-Chills
-Exhausting sweats
-Headaches
-Muscle aches
-Tiredness
-Vomitting
What category of people are at risk of malaria
Those with weak immune systems
(E.g children under 5, pregnant women and HIV positive people)
What are merozoites
The parasite formed when the liver bursts (after the infection of sporezites) which are releases to the blood stream
What are sporezoites
What the person is infected its after being injected by a mosquito which goes to asexually reproduce in the liver
What are schizonts
A new form of merozoites which bursts red blood cells (causing fever and sweating)
Why is malaria difficult to treat
Disease has many phases so it’s difficult to develop drains to treat all the (sometimes hidden) parasites. Also the parasite has developed resistance to many anti malarial treatments
What is the first stage of a fungi
Spores which are haploids (only have a single copy of their genetic material)
How do spores spread?
Grabbing to other organisms or being blown by wind
What is Mycellium?
The root like structures that spores grow to gain nutrients form their surroundings to grow the spore
Once the spores form a mycelium what happen
It can choose to reproduce sexually or asexually:
-Asexually will form more spores for further growth of additional mycelium
-Sexually will cause differ t mycelium to bond and form a combination of two or more nuclei to further grow the mycelium
What is plasmogamy
When haploid cells from two different mycelium fuse together to from a heterokaryotic cell with two or more nuclei
What is Karyogamy
The nuclei fuse to form a diploid zygote (they combine nuclei’s and form a zygote)
What happens once a zygote is formed?
The zygote uses meiosis to form spores which begins germination (spread of spores)
