Containing food particles will be digested by
lysosomes

Answer 17

Vacoule

Question 18

Means to eat

Answer 18

Phagocytosis

Question 19

To drink

Answer 19

Pinocytosis

Question 19

Exit

Answer 19

Exocytosis

Question 20

Cell will simply divide by mitosis and results in 2 essentially identical individuals

Answer 20

Binary Fission

Question 21

A progeny cell “the bud” is considerably smaller than the parent. It will late separate from the parent cell and grow to full size.

Answer 21

Budding

Question 22

Form nuclear copies called “schizonts” before
splitting to simultaneously produce many identical individuals called “merozoites”

Answer 22

Multiple Fission/Schizonony

Question 23

After a sexual reproductive stage; union of gametes before multiple fission/schizogony occurs.

Answer 23

Sporogony

Question 24

Fusion of 2 cells or gametes resulting in the formation of a zygote

Answer 24

Syngamy

Question 25

Temporarily fusing to allow exchange of chromosomes, when they separate, both conjugants have entirely new genetic information.

Answer 25

Conjugation

Question 26

Occurs before sporogony, will produce haploid (n) daughter cells instead of diploid (2n). When 2 haploids happen to meet, they will fuse to form a zygote. Will then make multiple copies of itself through sporogony.

Answer 26

Gametogony

Question 27

Mode of reproduction: Asexual, binary or multiple fission Sexual via syngamy Nucleus: 1

Answer 27

SARCOMASTIGOPHORA
