Question 4

Zoite

Answer 4

functional unit of protozoanontogeny; translates to “little animal”; invades cell and migrates

Question 5

Sporozoite

Answer 5

infective form found in a sporulated oocyst

Question 6

Answer 6

form which feeds and grows

Question 7

Merizoites

Answer 7

daughter cell resulting from schizogony

Question 8

Tachyzoites

Answer 8

form which divides rapidly

Question 9

Bradyzoites

Answer 9

form which divides slowly

Question 10

Binary Fission

Answer 10

nuclei divide first followed by the cytoplasm

Question 11

Budding

Answer 11

smaller individual form after nuclear division

Question 12

Schizogony (Merogony)

Answer 12

nucleus divides repeatedly, ultimately resulting in a schizont containing many merozoites

Question 13

Forms of asexual reproduction performed by protozoa

Answer 13

Binary Fission

Budding

Schizogony

Question 14

Characteristics of asexually producing protozoa

Answer 14

Short generation time

Exponential increase in zoites

Destruction of host cell in proportion to infection

Stops after fixed number of repetitions

Question 15

Sexual reproduction of protozoa occurs by ___________.

Answer 15

Sexual reproduction of protozoa occurs by gametogony or Sporogony.

Question 16

Merizoite can become either a _____________ then to a macrogamete or __________ then several microgametes.

Answer 16

Merizoite can become either a macrogametocyte then to a macrogamete _or _microgametocyte then several microgametes.

Question 17

When a microgamete fertilizes a macrogamete a _______ forms; then a wall forms around this and it becomes an ________.

Answer 17

When a microgamete fertilizes a macrogamete a zygote forms; then a wall forms around this and it becomes an oocyst.
