* feeds off of human red blood cells.
* flourishes only in healthy red blood.
* go through a series of steps on their way to causing disease in humans.
* has a relict plastid.
* have both a sexual and an asexual phase of development.
* multiply rapidly in the liver and then in red blood cells of the infected person.
* outwits the immune system.
* spend part of their life cycle in certain mosquitoes.

Malarial parasite
* are visible within the red blood cells.
* can develop resistance to anti-malarial drugs and pests to pesticides.

Microscopic parasite
* Some microscopic parasites cause diarrheal illnesses
  - perform beneficial cleaning services for their hosts
* can cause arthritis-like symptoms.

### parasite:

Mistletoe
* Most mistletoes contain chlorophyll.
* Most mistletoes grow on host plants
  - trees
* Most mistletoes have berries
  - flowers
  - fragrant flowers
  - green leaves
  - shape leaves
* Some mistletoe can be poisonous.
* Some mistletoes cause deformities
  - inflammatory reaction
  - grow as parasites on other parasitic mistletoes
* Some mistletoes have adverse effects
  - few disease problems
  - fruit
  - roots
  - serious adverse effects
  - make food
* are bushs.
  - structures
* includes cell membranes
  - corpi
  - cytoplasm
  - nuclei
  - plasma membranes
  - sections
  - vacuoles
* occur in localities.
* parasitic plant
* show effects.

### parasite | mistletoe:

American mistletoe
* Most american mistletoes have leaves.
* grows mainly through the southern states on a wide variety of trees.

Australian mistletoe
* Many Australian mistletoes are specific to one or a few host plants.
* are sensitive to fire, so bushfires prevent their spread.

### parasite | mistletoe:

Dwarf mistletoe
* Some dwarf mistletoes have chlorophyll.
* are more severe where fire has been suppressed
  - obligate parasites
* extract most of their carbohydrate requirements from host trees.
* grow into the bark and phloem of the tree.
* is the major disease of pines in the Rocky Mountains.
* parasite that causes the erratic growth of branches.
* parasitic plant that can infest many evergreen trees.
* parasitize conifer trees.
* reduces basal area growth of ponderosa pine in the Southwest.
* tend to be host specific.

European mistletoe
* Most european mistletoes have leaves
  - shape leaves
* is dioecious, with male and female flowers on separate plants.

Nematode parasite
* Most nematode parasites occur in environments
  - tropical environments
* Some nematode parasites cause symptoms.

Parasite control
* is an important aspect of management of young, growing horses
  - necessary for the health of the animal and to prevent internal parasites
  - often a detrimental culprit for poorly producing livestock
* makes use of both dewormers and appropriate management procedures
  - management procedures and dewormers
* necessity for elk as it is with cattle.

Parasitic plant
* Most parasitic plants absorb water.
* Most parasitic plants compete with host plants
  - obtain water
* Most parasitic plants produce flowers
  - seeds
* Some parasitic plants cause damage
  - severe damage
  - have no leaves
* form roots.
* get their nutrients from other plants, called host plants.
* obtain their nutritional requirements directly from their hosts
