B3: Quiz 2 – Answers
1)
a) Eukaryotic
b) Parasites are organisms that live on or inside another organism. The parasite benefits from the host by taking nutrients without giving anything in return
c)
i) Female mosquitos
ii) The female mosquitos get malaria from feeding off an animal that is infected with malaria
iii) The infected female mosquitos infect humans with malaria when they bite them
d) A fever and flu like symptoms
e) Any 3 from:
2)
a) Fungi
b) Athlete’s foot can cause the skin to become red and flaky or cause the skin to become white and start cracking
c) Touching surfaces that have been in contact with individuals who are infected with athlete’s foot, such as the floor in a changing room
d) Antifungal medication
3)
a) Fungi
b) The leaves of the rose plants develop black or purple spots. The infected leaves then turn yellow and may even drop off
c) Most of the photosynthesis in plants takes place in the leaves. Therefore, if the leaves fall off, the plant photosynthesises less, which result in less glucose being produced. This causes the plant to have reduced growth/ may result in the plant dying
d) Rose black spot can be spread through the wind, water or direct contact from the gardener
e) Using fungicides and removing infected leaves (we also destroy the infected leaves so that other plants do not get infected)
