A

Sporozoites, gametocytes.

20
Q

What are characteristics of true multicellularity?

A

Nuclei, other membrane bound organelles, sexual life cycle, cytoskeleton, and linear chromosomes.

21
Q

Describe animans meiosis.

A

Haploids produced by meiosis. Form a diploid zygote that divides in mitosis. Produces multicellular diploid cell organisms.

22
Q

Describe fungi meiosis.

A

Meiosis with NO mitosis. Results in haploid cells dividing by mitosis.

23
Q

Describe plants and some algae meiosis.

A

Mitosis in both haploid and diploid.

24
Q

What are the three types of meiosis?

A

Zygotic, spored, and gameitc.

25
Q

Are zygotic, spored, and gametic haploid or diploid dominant?

A

Zygotic - Diploid.
Spored - Both
Gametic - Haploid

26
Q

What does isogamy mean?

A

Identical, but with chemical differences.

27
Q

What does anisogamy mean?

A

similar, but different sizes.

28
Q

What does oogamous mean?

A

Female gamete losing mobility.

29
Q

What does isomorphic mean?

A

gametophyte and sporophyte identical in appearance.

30
Q

What does heteromorphic mean?

A

Different in shape.

31
Q

Describe the kingdom protista.

A

It is the “trash can” or “dumping ground”. Derived relative to prokaryotic lineage, but is ancestral to animals, plants, and fungi. Not monophyletic.

32
Q

What does polytomy mean?

33
Q

What are the protist clades?

A

Excavata, SAR, Archaeplastida, and Unikonta.

34
Q

What are the clades of excavada?

A

Diplomonadida, parabasala, kineto plastida, and eudlenophyta.

35
Q

Describe Diplomonadida

A

They are double nucleus, heterotrophic, free living parasites. They have 2, 4, or 8 flagella. They have no mitochondria and many live in insects or vertebrates

36
Q

What is Giardia lamblia and which protist clade is it a part of?

A

It is an intestinal virus and it is in diplomonadida.

37
Q

Describe Parabasala

A

Parabasal body. They are heterotrophic and they can live in the absence of oxygen. 4 to 1000’s of flagella.

38
Q

What is a parabasl body?

A

Large, modified golgi apparatus.

39
Q

What is Trichomonas vaginalis and which protist clade is it a part of?

A

It is a human urogenital tract. causes STI mostly in women. It is part of parabasala.

40
Q

What is Trichonympha and which protist clade is it a part of?

A

It is in termite guts and it is a part of parabasala.

41
Q

Describe Kinetoplastida

A

It is a large mitochondrion with a large mass of DNA. Most of them are parasitic.

42
Q

What is Trypanosoma brucei and which protist clade is it a part of?

A

It is carried by a fly, called “African sleeping sickness”. It is a part of kinetoplastida. They need to invade the immune system of a host.

43
Q

What is T. cruzi and which protist clade is it a part of?

A

It causes chagas disease “kissing bugs”. It causes digestive and cardiac problems. It is part of kinetoplastidas.

44
Q

Describe Euglenozoa

A

Colorless heterotrophs and green photoautotrophs. They do longitudinal binary fission.

45
Q

What is Euglena and which protist clade is it a part of?

A

It has 2 flagella in the flagellar reservoir. It is part of Euglenozoa.
