What method of reproduction do algae use?

A

Asexual

43
Q

What type of environment do algae typically inhabit?

A

Aquatic environments

44
Q

Why are algae typically found in aquatic habitats?

A

Water is necessary for their growth and reproduction

45
Q

This eukaryotic group is made up of unicellular or filamentous photoautotrophs

A

Algae

46
Q

Members of this eukaryotic group lack roots, stems, and leaves

A

Algae

47
Q

Members of this eukaryotic group reproduce asexually and are mostly aquatic

A

Algae

48
Q

What 3 factors determine where algae is located in a body of water?

A

Nutrient availability; light wavelengths; attachment surfaces

49
Q

What are algal blooms?

A

Increases in planktonic algae that can result in toxin release or die and consume oxygen

50
Q

How much of Earth’s O2 do algae produce?

A

80%

51
Q

What do algae fix CO2 into?

A

Organic molecules

52
Q

Do protozoa require a lot of water?

A

Yes

53
Q

What outer structure do protozoa have that requires them to have specialized structures to take in food?

A

Protective pellicle

54
Q

How do ciliates eat?

A

By waving cilia toward mouth-like cytosome

55
Q

How do amebae eat?

A

By phagocytizing food

56
Q

In protozoa, where is food digested?

A

In vacuoles

57
Q

In protozoa, where is waste eliminated?

A

Through an anal pore

58
Q

This group of eukaryotes requires a large supply of water, and many have specialized structures for food intake

A

Protozoa

59
Q

These protozoa eat by waving cilia towards their mouthlike cytosomes

A

Ciliates

60
Q

These protozoa eat by phagocytizing their food

A

61
Q

What disease does Plasmodium cause?

A

Malaria

62
Q

What mosquito does Plasmodium reproduce sexually within?

A

Anopheles mosquito

63
Q

What life cycle stage of Plasmodium does a mosquito inject into its bite?

A

Sporozoite

64
Q

What happens to the Plasmodium sporozoite after its injected?

A

It undergoes schizogony in the liver, producing merozoites

65
Q

What do merozoites infect?

A

Red blood cells

66
Q

What do merozites form inside red blood cells?

A

Ring stage

67
Q

What happens to the red blood cells full of merozoites?

A

A

Merozoites

72
Q

A ring stage forms in these after merozoites infect them

Red blood cells

73
Q

After red blood cells rupture, these can infect new red blood cells

Q

Do Plasmodium reproduce asexually in human hosts?

A

Yes

75
Q

Do Plasmodium reproduce asexually in mosquitoes?

A

No

76

84
Q

Do helminths have a complex reproductive system?

A

Yes

85
