How do spore-forming protists such as plasmodium differ from other protists in terms of movement

Plasmodium is the agent of malaria. It is like a parasite because it lives in its host, in its case the mosquito.

It has three stages of  life cycle. 1) gametocytes ; 2) sporozoites ; 3) merozoites

As gametocytes, it lives in the bellies of a female anopheles mosquito. They develop and change into sporozoites. After becoming sporozoites, they migrate to the salivary glands of the mosquito. As the female mosquito feeds, the sporozoites are injected into the host. The sporozoites make their way to the host's liver and change into merozoites and attack the red blood cells of the host. Thus, the beginning of malaria.

Protists such as plasmodium actually use a passive form of movement. They form reproductive spores that enter the cells of other organisms and live as parasites. Then, their host cells do all of the actual moving for them.

Are you asking about a street map usage  if so here is your answer  a street map for a very limited area could simply be a bit map or a .jpg image.  but a more general map would probably store the streets as vectors.  but you shouldn't assume that there is one way to do it
