Q

Process of protozoan conjugation

A
  1. Haploid micronucleus fuses with the haploid micronucleus within the cell
  2. Parent cells separate, each now a fertilized cell
  3. When cells divide, they producd daughter cells with recombined DNA

Q

A sexual reporduction where the protozoan produce gametes (gametocytes), which are haploid sex cells. During reproduction, two gametes fuse to form a diploid zygote.

Q

Where does the waste of a protozoa eliminated?

A

Plasma membrane or anal pore

Q

A single-celled eukaryotes sith a feeding groove in the cytoskeleton and are spindle-shaped and possess flagella

A

Euglenozoa

23
Q

Two phyla of a euglenozoa that lack mitochondria

A

Diplomonads and Parabasalids

24
Q

Are euglenoids chemoautotrophs or photoautotrophs, or both

A

Both

25
Q

A semi-rigid plasma membrane of a euglenoids that moves by means of a flagellumnat the anterior end

A

Pellicle

26
Q

What do most euglenoids have at the anterior end

A

Red eyespot

27
Q

What does the euglenoid, a carotenoid-containing organelle, use to sensenlight and direct the cell in the appropriate direction

A

Preemergent flagellum

28
Q

Moves by extending blunt, lobe like projections of the cytoplasm

A

Amebae

29
Q

Lobe like projections of the cytoplasm of an amebae

A

Pseudopods

30
Q

Protoza that are not motile in their mature forms and are obligate intercellular parasites

Apicomplexa

31
Q

Apicomplexa lns are characterized by the presence of complex special organelles at the _____ of their cells

A

Apex

32
Q

ApicL complexes

A

Rhoptries, micronemes, and dense granules

Q

What does an apicomplexa involve that make their life cycle complex

A

Transmission between several hosts

34

Have cilia that are arranged in precise rows on the cell. They are moved in unison to propel the cell through its environment and to bring food particles to the mouth

A

Ciliates

35

A kind of ciliate that has a specialized structures for ingestion (cytosome), elimination of waste (anal pore), and the regulation of osmotic pressure (contractile vacuoles)

A

Paramecium
