  protists?

5

• bacteria

6
Question 3

• What is the difference between a
  eukaryotic cell and a
  prokaryotic cell?

7

• Prokaryotic cells (bacteria) dont have a nucleus
  to contain DNA, while eukaryotic cells do.

8
Question 4

• Why wouldnt you find protists living in a
  swimming pool or in tap water?

9

• Tap water and swimming pool water is filtered and
  has chlorine added to remove and destroy microbes
  such as protists.

  food
• ____________ - like protist
• ____________ - like protist

11

• Plantlike
• Animal-like
• Funguslike

12
Question 6

• How does a funguslike protist obtain its food?

13

• They decompose dead things and absorb their food
  like fungi do.

14
Question 7

• What major event in world history was caused by a
  funguslike protist?

15

• The Great Irish Potato Famine of 1845-1846

16
Question 8

• Explain how a plantlike protist obtains its food.

17

• They perform photosynthesis like plants do.

18
Question 9

• Most protists are

19

• Most protists are unicelled, (with the exception
  of some species of algae.)

20
Question 10

• Why are protists called the middle
• kingdom?

21

• They are more complex than bacteria but less
  complex than plants, animals and fungi
• They arrived on Earth after bacteria but before
  plants, animals and fungi.

22
Question 11

• When this happens, people are asked not to swim
  or eat any seafood that lives in the ocean or
  near the shore, like crabs and some fish. What is

24
Question 12

• What is so unique about the protist euglena?

25

• Euglena can perform photosynthesis (plantlike)
  and can move and eat (animal-like)

26
Question 13

• How do animal-like Protists obtain their food?

27

• Animal-like protists eat food like animals do.

28
Question 14

• What is the difference between cilia and
  flagella?

29

• Cilia are tiny hair-like structures that sway
• Flagella are whip-like tails

30
Question 15

• Name two reasons why cilia are helpful to
  protists.

31

• Cilia are used for movement and feeding

32
Question 16

• Name two reasons why flagella are helpful to a
  protist.

33

• Flagella are used for movement and feeding.

34
Question 17

• Why is the term protozoans appropriate to
  describe the animal-like protists?

35

• According to fossil evidence, protozoans lived on
  Earth before animals.

36
Question 18

• Explain how protists such as diatoms and
  radiolarians can contribute to the formation of
  sedimentary rocks.

37
Diatoms

• Because they are so beautiful,they are often
  referred to as jewel boxes.

38

• Their shells fall to the ocean floor and become
  sediments, which can be compacted together to
  form sedimentary rock.

39
Question 19

• Name an illness or a disease that is caused by a
  protist.
• How is it transmitted from one host to another?

40

• MALARIA is caused by a protist called Plasmodium

  water.

41
Question 20

• Algae are helpful to humans and other animals in
  many ways. Explain 2 of them

42
Algae provide

• Oxygen
• Food
• Shelter for animals
• Products such as agar, thickening agents, and
