FSc Part 1 Biology chapter 7: Kingdom Protista MCQs with answers
By Team Megalecture · Updated 4 Nov 2026
21 exam-style questions on Kingdom Protista, each with the answer and a short explanation. Ten of them are below to try. The chapter test draws ten fresh questions each time and is marked the moment you finish, with your score by topic.
Try each one, then open the answer. These ten stay the same; the test draws new ones every time.
1. Kingdom Protista is best described as a group of
A
acellular particles that reproduce only inside host cells
B
prokaryotic organisms with no true nucleus
C
multicellular heterotrophs that lack a cell wall
D
eukaryotes that are not plants, animals or fungi
Show answer
Answer: D. Protists are eukaryotes, mostly unicellular or simple, that do not fit into the plant, animal or fungal kingdoms.
2. The feeding stage of a plasmodial slime mold is
A
a branched septate mycelium with chitin walls
B
a mass of separate amoeboid cells that feed independently
C
a multinucleate mass of cytoplasm without cell walls
D
a colony of flagellated cells held in a jelly matrix
Show answer
Answer: C. The plasmodium is a single multinucleate mass that creeps and engulfs food. Cellular slime molds feed as separate amoeboid cells.
3. Dinoflagellates are recognised by
A
an apical complex used to invade host cells
B
a flexible protein pellicle and one long flagellum with an eyespot
C
a hard silica shell in two overlapping halves
D
cellulose plates and two flagella lying in grooves
Show answer
Answer: D. Dinoflagellates have armour of cellulose plates, one flagellum in a transverse groove and one in a longitudinal groove. Some cause red tides.
4. Phytophthora infestans, which caused the Irish potato famine, is a
A
true fungus of Ascomycota
B
water mold (oomycete)
C
slime mold
D
bacterium
Show answer
Answer: B. Phytophthora is an oomycete (water mold) that causes late blight of potato. Water molds have cellulose walls, unlike true fungi.
5. Actinopods such as radiolarians have
A
calcium carbonate shells and cilia
B
no skeleton and many cilia
C
cellulose plates and two flagella
D
glassy silica shells and thin axopodia
Show answer
Answer: D. Radiolarians have silica shells with slender pseudopodia called axopodia. Calcareous shells belong to foraminiferans.
6. Euglena kept in light with only mineral salts stays green and multiplies. Kept in the dark in a solution containing sugars, it also multiplies but loses its chlorophyll. This shows that Euglena can
A
live only as a heterotroph
B
make food only by photosynthesis
C
obtain food by photosynthesis and by absorbing organic nutrients
D
make its food only from inorganic chemicals
Show answer
Answer: C. It photosynthesises in the light and, when there is no light, takes in dissolved organic food, so it can be autotrophic and heterotrophic (mixotrophic). This is one reason Euglena is difficult to place as a plant or an animal.
7. Euglena has a flexible protein covering beneath its plasma membrane called the
A
cell wall
B
pellicle
C
test
D
frustule
Show answer
Answer: B. The pellicle lets Euglena change shape. It has no cellulose cell wall.
8. Green algae are thought to be the ancestors of land plants because they
A
have chlorophylls a and b, starch and cellulose walls
B
store their food as laminarin and have cell walls containing algin
C
contain phycoerythrin and live in very deep water
D
are all multicellular and have true roots and stems
Show answer
Answer: A. Green algae share chlorophylls a and b, starch storage and cellulose walls with plants.
9. Paramecium has two kinds of nuclei. The micronucleus is mainly concerned with
A
osmoregulation and removal of excess water
B
controlling everyday metabolism and growth
C
sexual reproduction (conjugation)
D
feeding by forming food vacuoles
Show answer
Answer: C. The micronucleus takes part in conjugation. The macronucleus controls metabolism and growth.
10. Trichonympha lives in the gut of termites and helps them by
A
killing parasites
B
digesting the cellulose in wood
C
producing vitamins by photosynthesis
D
fixing nitrogen
Show answer
Answer: B. Termites cannot digest cellulose; this zooflagellate does it for them in a mutualistic relationship.
