Answers:
1.)
Solution: b) Not well defined
Kingdom Protista include all the single celled eukaryotes. This kingdom contain boundaries which are not well defined.
2.)
Solution: a) Diatoms cell wall form two overlapping thin shell
The overlapping of diatoms is like soap box but it’s not a real soap box it’s just a similarity so option a is correct
3.)
Solution: a) Aquatic
The kingdom Protista include plankton that lives in water bodies. Hence, the organisms of kingdom Protista are primarily aquatic.
4.)
Solution: d) Silica
Silica makes the walls of diatoms indestructible. When diatoms die the silica of their cell wall get deposited as diatomaceous earth over time.
5.)
Solution: d) Pellicle
In the Euglenoids, protein rich layer is present instead of cell wall. Therefore, Pellicle is the protein rich layer which makes the body flexible in the Euglenoids.
6.)
Solution: d) Most Euglenoids are found in stagnant water.
Most Euglenoids are found in stagnant water but not all there are some who are found in fresh water but they are very few so option d is correct
7.)
Solution: c) Two
Body of the Euglenoids is flexible and contains a long flagella and a short flagella. Hence, Euglenoids have two flagella.
8.)
Solution: c) Gonyaulax
Gonyaulax is a dinoflagellate who releases some toxins which make sea tides appear red. Toxins released in such huge amount could even kill aquatic organisms.
9.)
Solution: b) Amoeboid protozoans put out false feet or pseudopodia to capture their prey.
All the statements except ‘Amoeboid protozoans put out false feet or pseudopodia to capture their prey’ are incorrect. In the correct statement, amoeboid protozoans put out their false feet which captures prey.
10.)
Solution: d) Photosynthetic during day and heterotrophic during night.
Euglenoids show photosynthetic ability like plants when sunlight is present but when sunlight is absent it becomes heterotrophic by predating on other smaller organisms
11.)
Solution: d) Many years
These organisms of Protista are extremely resistant and they can survive for many years. Even they can survive under adverse conditions.
12.)
Solution: c) Trypanosoma
The parasite Trypanosoma is a flagellated protozoan which causes sleeping sickness.
13.)
Solution: b) Flagellated protozoan
Trypanosoma is a free living organism that have flagella. This is responsible for causing diseases. Hence, Trypanosoma is a flagellated protozoan.
14.)
Solution: b) Actively moving
Ciliaited protozoans are actively moving water with the help of their thousands of cilia. Cilia is present in the cell walls which helps in movement.
15.)
Solution: c) Both asexually and sexually
The organisms of Protista involve processes like cell fusion and zygote formation. Hence, reproduction in the organisms of Protista occurs asexuallyand sexually.
16.)
Solution: d) Diatoms
Diatomaceous earth is deposited from billions of years and are present in large amount so they are chief producers in the oceans.
17.)
Solution: b) Outside of the cell surface
Ciliated protozoans are generally aquatic. Ciliated protozoans have thousands of cilia for the locomotion and have a cavity called gullet which opens to the outside of the cell surface.
18.)
Solution: b) 1-iii), 2-ii), 3-i)
Malaria comes under Sporozoans, Trypanosoma comes under flagellated protozoan whereas desmids or golden algae is a part of cryophytes.
19.)
Solution: b) Humans
The Plasmodium causes malaria in the humans because it is a malarial parasite. Hence, a disease which is caused by Plasmodium has staggering effects on the human.
20.)
Solution: a) All dinoflagellates are marine
Most dinoflagellates are marine but not all are so option is incorrect. As some are also found in fresh water as well so not all are marine.
21.)
Solution: d) Pellicle
Pellicle is a protein rich layer which makes the body of Euglenoids flexible.
22.)
Solution: b) Desmids
Golden algae is also known as desmids because of their distinctive golden colour.
23.)
Solution: a) 2
Euglenoids have 2 flagella a short and a long flagella. Short flagella does not protrudefrom the cell wall whereas long flagella protrude out of the cell and can be seen with help of a light microscope.
24.)
Solution: b) Forms fruiting bodies bearing spores at their tips
To escape the unfavourable conditions or to ensure survivability plasmodium forms fruiting bodies bearing spores at their tips and these spores are carried away to faraway places with wind.
25.)
Solution: c) Protozoans
Protozoans are primitive relative of animals because they are heterotrophic like animals and also they show movement with the help of locomotory organs similar to animals.
26.)
Solution: d) Both (a) & (b)
Protists reproduce asexually and sexually by cell fusion and zygote formation whereas vegetative propagation is for plants.
27.)
Solution: c) Saprophytic
They are saprophytic because they ingest fungal spores, bacteria and possibly other protists.
28.)
Solution: d) Amoeboid protozoans
Amoeboid protozoans show movement and capture their prey with the help of pseudopodia also called as false feet.
29.)
Solution: b) Sporozoans
They are called infectious because at this particular stage Sporozoans causes disease like malaria which most dangerous disease for humans.
30.)
Solution: c) Paramoecium
Paramoecium have many cilia at their cell surface for movement. So, they are ciliated Sporozoans.
