3.1.5 Protist Diseases

• Protists can be unicellular or multicellular

  True
• Match the protist with the disease it causes and its mechanism:

  Giardia lamblia ↔️ Giardiasis, adheres to intestinal lining

  Entamoeba histolytica ↔️ Amoebic dysentery, lyses intestinal cells

  Plasmodium spp. ↔️ Malaria, infects red blood cells
• How is malaria transmitted to humans?

  Mosquito bites
• Malaria is caused by the sporozoan Plasmodium and transmitted through mosquito bites
• Protists are eukaryotic organisms that are not fungi, plants, or animals
• Match the organelle with its function:

  Mitochondria ↔️ Energy production

  Chloroplasts ↔️ Photosynthesis
• Flagellates cause giardiasis and are transmitted through contaminated water or food


  True
• Arrange the following characteristics of protists in a logical order:

  1️⃣ Eukaryotic cell type

  2️⃣ Unicellular or multicellular

  3️⃣ Complex cell structure

  4️⃣ Autotrophic or heterotrophic nutrition
• Sporozoans like Plasmodium protozoa are responsible for the deadly malaria
• Giardia lamblia causes giardiasis by adhering to the intestinal lining

  True
• What are the primary mechanisms by which protists cause diseases?

  Direct invasion, toxin production
• Protists lyse host cells to replicate and spread within the host.


  True
• Protists are eukaryotic organisms that are not fungi, plants, or animals
• What are the two types of nutrition found in protists?

  Autotrophic and heterotrophic
• What are the symptoms of giardiasis caused by Flagellates?

  Diarrhea, abdominal cramps
• How is malaria transmitted to humans?

  Mosquito bites
• How does nutrient competition by protists harm the host?

  Leads to malnutrition
• Match the protist with its disease and mechanism:

  Giardia lamblia ↔️ Giardiasis, adheres to intestinal lining

  Entamoeba histolytica ↔️ Amoebic dysentery, lyses intestinal cells

  Plasmodium spp. ↔️ Malaria, infects red blood cells
• Protists can lyse or break open host cells to replicate and spread within the host.


  True
• What is the primary disease caused by Giardia lamblia?

  Giardiasis
• Protists cause diseases through several key mechanisms
• Protists can be autotrophic or heterotrophic
• Match the protist type with its disease and transmission method:

  Sporozoans ↔️ Malaria ||| Mosquito bites

  Amoebae ↔️ Amoebic dysentery ||| Contaminated water
• Protists have organelles like mitochondria and chloroplasts


  True
• What are four mechanisms by which protists cause diseases?

  Direct invasion, toxin production, nutrient competition, inflammatory response
• Entamoeba histolytica causes amoebic dysentery by lysing intestinal cells
• Some protists release toxins that harm cells and disrupt body functions
• Match the protist with the disease it causes and its mechanism:

  Giardia lamblia ↔️ Giardiasis, adheres to intestinal lining

  Entamoeba histolytica ↔️ Amoebic dysentery, lyses intestinal cells

  Plasmodium spp. ↔️ Malaria, infects red blood cells
• Protists can be either unicellular or multicellular.


  True
• Order the major types of protists that cause diseases based on their infection method:

  1️⃣ Flagellates (contaminated water or food)

  2️⃣ Amoebae (contaminated water or food)

  3️⃣ Ciliates (contaminated water or food)

  4️⃣ Sporozoans (mosquito bites)
• Balantidiasis caused by ciliates results in severe diarrhea and intestinal ulcers.


  True
• Protists can directly enter and colonize host tissues
• Order the mechanisms by which protists cause diseases based on their impact on the host:

  1️⃣ Direct Invasion (colonize host tissues)

  2️⃣ Toxin Production (damage cells)

  3️⃣ Nutrient Competition (lead to malnutrition)

  4️⃣ Inflammatory Response (damage tissues)

  5️⃣ Cell Lysis (replicate and spread)
• Some protists release harmful toxins that damage cells and disrupt normal bodily functions
• Match the protist with the disease it causes:

  Giardia lamblia ↔️ Giardiasis

  Entamoeba histolytica ↔️ Amoebic dysentery

  Plasmodium spp. ↔️ Malaria
• Which protist infects red blood cells and triggers malaria?

  Plasmodium spp.
• Arrange the disease mechanisms of protists in a logical order:

  1️⃣ Direct Invasion

  2️⃣ Toxin Production

  3️⃣ Nutrient Competition

  4️⃣ Inflammatory Response

  5️⃣ Cell Lysis
• What is the primary symptom of Giardiasis?

  Diarrhea
• Amoebic dysentery can lead to liver abscesses.


  True
• Which protist type primarily causes gastrointestinal issues by invading the intestinal lining?

  Flagellates
