Rose black spot
respiration / photosynthesis / bacterial / fungicides / fungal / red / black / wind
- Rose black spot is a disease that causes purple or spots develop on leaves, which then often turn yellow and drop off.
- This reduces and so also reduces the growth of the plant.
- It can be spread by water, or the .

Protists are often transported between hosts by other organisms. We call these other organisms:
Vectors
Pathogens
Commensals

Malaria
bacteria / protist / fatal / fevers / rashes / mosquitoes / leeches
- The organisms that cause malaria are a type of .
- They are transported between hosts by .
- The symptoms include recurrent and headaches, and in extreme cases it can be .

Suggest three ways we might try to reduce the spread of malaria.
