Weekly Quiz Competition

Question 1
1 / -0

Mosses and ferns are found in moist and shady places because both

A
Depend for their nutrition on microorganisms which can survive only at low temperature

B
Do not need sunlight for photosynthesis

C
Require presence of water for fertilisation

D
Cannot compete with sun-loving plants

Solution

Mosses and ferns are present in moist places as fertilization takes place only in presence of water, through motile antherozoids that swim to reach the archegonium.
So, the correct answer is 'Require presence of water for fertilisation'
Question 2
1 / -0

Give examples of division pteridophyta.

A
Adiantum and Lycopodium

B
Marsilea and Selaginella

C
Adiantum and Selaginella

D
All of above

Solution

Adiantum, Lycopodium, Marsilea and Selaginella are multicellular autotrophic plants, they belong to kingdom plantae, sub-kingdom: cryptogamae and division pteridophyta.
Question 3
1 / -0

Colouration in phaeophyceae is due to the main pigment

A
Carotene

B
Fucoxanthin

C
Phycoerythrin

D
Lycopene

Solution

Phaeophyceae are brown algae that are mostly marine in habitat. Their brown colour is due to the golden brown xanthophyll pigment fucoxanthin. They are multicellular, plant body is called thallus and are immobile.
So, the correct answer is option B.
Question 4
1 / -0

Which of the following is the correct sequence during alternation of generations in a flowering plant?

A
Sporophyte, Meiosis, Spores, Gametophyte, Gametes, Fertilisation, Diploid zygote

B
Sporophyte, Mitosis, Gametophyte, Meiosis, Spore

C
Haploid gametophyte, Gametes, Meiosis, Fertilization, Diploid sporophyte

D
Sporophyte, Spores, Meiosis, Gametophyte, Gametes

Solution

The plant exhibit alternation of generations in their life cycle. The plant is the diploid sporophytic phase that produces the haploid spores through meiosis which develop to form the gametophyte. The haploid gametophyte produces haploid gametes which fuse during fertilization to form the diploid zygote which develops into the sporophyte (plant).
Thus, the correct answer is option A.
Question 5
1 / -0

Alginic acid is a product of

A
Red algae

B
Green algae

C
Blue green algae

D
Brown algae

Solution

Alginic acid, also called as algin or alginate, is an anionic polysaccharide distributed widely in the cell walls of brown algae, where through binding with water it forms a viscous gum. In extracted form, it absorbs water quickly; it is capable of absorbing 200-300 times its own weight in water. Its colour ranges from white to yellowish-brown. It is sold in filamentous, granular or powdered forms.
Question 6
1 / -0

Study the following lists:
List-I List -II

(A) Anucleate (1) Spirogyra gamciangium
(B) Uninucleate (2) Rhizopus chlamydospore
(C) Multinucleate (3) Pteris neck canal cell
(D) Binucleate (4) Vitis matured sieve element
(5) Akinite of Spirogyra

A
A- (IV), B- (I), C- (III), D- (II)

B
A- (I), B- (III), C- (II), D- (IV)

C
A- (IV), B- (I), C- (II), D- (III)

D
A- (I), B- (IV), C- (V), D- (II)

Solution

Sieve elements are living cells. They are unique in lacking a nucleus at maturity. A single nucleus is present at the central cytoplasmic mass that holds in the center of vacuole in Spirogyra. Chlamydospores are formed during unfavorable conditions. They are binucleate spores produced in clusters on uredium.
Question 7
1 / -0

Which of the following division of kingdom plantae and sub-kingdom cryptogamae can reproduce sexually by formation of gametes.

A
Thallophyta

B
Bryophyta

C
Pteridophyta

D
All of above
Question 8
1 / -0

Read the following statements and choose the correct option.
I. Leptosporangiate development of sporangium is found in all members Pteropsida.
II. Seed habit is shown by Sellaginella.
III. Gnetum leaves are monomorphic and pinnately compound.
IV. Zygotic meiosis is found in Volvox, Chlamydomonas and Ulothrix.
Choose the correct option.

A
I and IV

B
I and II

C
I, II and IV

D
All of these
Question 9
1 / -0

Study the following lists.
List-I List-II
(A) Agar-Agar     (I) Saccharomyces
(B) Biofertilizers (II) Basidiomycotina
(C) Mushrooms    (III) Red algae
(D) B-Vitamins    (IV) Blue green algae
(V) Vibrio
The correct match is

A
(A)- (V), (B)- (I), (C)- (IV), (D)- (II)

B
(A)- (IV), (B)- (II), (C)- (III), (D)- (V)

C
(A)- (II), (B)- (III), (C)- (V), (D)- (IV)

D
(A)- (III), (B)- (IV), (C)- (II), (D)- (I)

Solution

Agar is a natural polysaccharide (starch) product extracted from certain species of red algae like Gelidium, Gracilaria etc.
Biofertilizers are organisms that enrich the nutrient quality of soil. The main sources of biofertilizers are cynobacteria (blue-green algae). Dominant nitrogen-fixer blue-green algae are Anabaena, Nostoc etc.
Basidiomycota are filamentous fungi composed of hyphae, and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). It includes groups like Mushrooms, puffballs etc.
Saccharomyces cerevisiae contains several B vitamins. These include vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B7 (biotin), and vitamin B9 (folic acid).
Hence, option D is correct.
Question 10
1 / -0

In which of following groups of plants, the life cycle includes the gametophytic phase which is dominant, photosynthetic, independent and sexually reproducing?

A
Angiosperms

B
Gymnosperms

C
Bryophyta

D
Pteridophyta

Solution

Bryophytes alternate a gametophytic generation with a sporophytic one. Each of the haploid spores is capable of developing into a multicellular, haploid individual, the gametophyte. Gametophyte is formed from the spores and give rise to the haploid gametes i.e., are sexually reproducing.
In bryophtyes, these are dominant, independent photosynthetic plants.
Thus, the correct answer is option (C).
