Protists

Question 1

Protist

Answer 1

eukaryotic, most are aerobic and single celled, all live in moist environment

Question 2

parasite

Answer 2

(Sporozoans)non-motile, live inside a host, one type causes malaria

Question 3

cytoskeleton

Answer 3

network of protein filaments and tubules which give the organism shape

Question 4

pseudopod

Answer 4

(the blobs) most are free living, also called sarcodines, move using pseudopods (plasma extensions) reproduce by binary fission, eugluf bits of food by phagocytosis which involves flowing around and over food particles

Question 5

cilium

Answer 5

the hairy ones, live in fresh and marine water, usually reproduce by binary fission but can also reproduce by conjugation

Question 6

flagellum

Answer 6

whip-like extensions that help with movement

Question 7

mutualistic

Answer 7

an interaction between individuals of different species that results in positive (beneficial) effects such as reproduction and/or survival of interacting species

Question 8

Amoeba

Answer 8

a pseudopods part of the protozoans

Question 9

Dinoflagellate

Answer 9

plant like, spin around using two flagella, form toxins that can kill animals and sometimes people

Question 10

Oral Groove

Answer 10

extends from the anterior end to beyond the middle

Question 11

Oral Gullet

Answer 11

helps in the intake and digestion of food in these organisms in protozoans like paramecium

Question 12

Food Vacuole

Answer 12

a membrane-enclosed sac, which has a digestive function, digesting the ingested food. present in unicellular protozoans such as amoeba, plasmodium.

Question 13

Contractile Vacuole

Answer 13

controls the intracellular water balance by accumulating and expelling excess water out of the cell

Question 14

Euglenoids

Answer 14

Aquatic, move like animals, photosynthetic in light, heterotrophic in dark, reproduce by binary fission

Question 15

Phytoplankton

Answer 15

microscopic marine algae

Question 16

Diatom

Answer 16

plant like, have shells made of silica, glass-like,

Question 17

symbiotic relationship

Answer 17

mutually beneficial relationship

Question 18

why are protists grouped together in this Kingdom

Answer 18

three major phyla based on their nutritional needs

Question 19

how are protists classified

Answer 19

1. Animal-like: the protozoa
   2.Plant-like: the algae or protophyta
2. Fungus-like: the moulds

Question 20

how do amoebas move & feed

Answer 20

move by using pseudopods, they eat by engulfing bits of food by phagocytosis

Question 21

how do ciliates move & feed

Answer 21

move by beating tiny hairs called cilia they eat by phagocytosis

Question 22

how do flagellates move & feed

Answer 22

move by using the whip-like extension called flagella they eat by phagocytosis

Question 23

plasmodium life cycle

Question 24

Malaria life cycle

Answer 24

zygo
