Weekly Quiz Competition

Question 1
1 / -0

If the root cell of a pteridophyte contains 10 chromosomes, then the chromosome number in indusium, sperm mother cell and spore mother cell are respectively.

A
10,5,10

B
10,5,5

C
10,10,10

D
5,10,10
Question 2
1 / -0

You discover a new species of a plant. You discover that it produces motile sperms and dominant generation has diploid cells. It belongs to

A
Bryophyte

B
Angiosperm

C
Gymnosperm

D
Pteridophyte

Solution

Amongst Bryophytes, Pteridophytes, Gymnosperms and Angiosperms, only bryophytes and pteridophytes produce motile sperms which swim in the surrounding medium to reach female gamete for the process of fertilisation. While. in pteridophytes only the dominant generation is diploid. The dominant generation in bryophytes is haploid.
So, the correct answer is 'Option D- Pteridophytes'.

A
$$24$$ chromosomes

B
$$36$$ chromosomes

C
$$12$$ chromosomes

D
$$48$$ chromosomes

Which of the following is the common character between algae and bryophyta?

A
They are autotrophic.

B
Vascular tissue is absent.

C
Gametophyte is the main plant body.

All of the above

1 / -0

Gnetum resembles angiosperms in showing which one of the following types of female gametophyte development?

A
Monophonic

B
Bishopric

C
Endymion

D
Tetrasporic
Question 6
1 / -0

1. Magnoliaceae
2. Degeneriaceae
3. Winteraceae
4. Annonaceae
Select the correct answer.

B
Growth and reproduction are mutually exclusive events

C
Asexual reproduction occurs by mitospores

D
Both (1) and (3)
Question 8
1 / -0

Read the given paragraph.
Where there is alternation of generations, the haploid multicellular plant is called a (i) and the diploid multicellular plant is called (ii) . (iii) generation is the dominant phase in algae showing haplontic type of life cycle. Bryophytes and pteridophytes usually possess (iv) types of life cycle.
Select the correct sequence of terms to complete the above paragraph.

A
(i)-Sporophyte, (ii)-Gametophyte, (iii)-Gametophyte, (iv)-Diplontic

B
(i)-Gametophyte, (ii)-Sporophyte, (iii)-Sporophyte, (iv)-Haplontic

C
(i)-Sporophyte, (ii)-Gametophyte, (iii)-Sporophyte, (iv)-Haplodiplontic

D
(i)-Gametophyte, (ii)-Sporophyte, (iii)-Gametophyte, (iv)-Haplodiplontic
Question 9
1 / -0

Consider the following statements for algae.
a. Fusion between one large, non - motile female gamete and a smaller, motile male gamete is termed as oogamous.
b. Fusion of two gametes dissimilar in size is termed as isogamous.
c. Fusion of two gametes similar in size is called anisogamous.
d. In Chlorophyceae, the major photosynthetic pigments are chlorophyll a and b, and the food is stored as starch.
e. In Rhodophyceae, the major photosynthetic pigments are chlorophyll a and d, and the food is stored as mannitol.
Of the above statements:

A
a and e are correct

B
c and e are correct

C
a and b are correct

D
a and d are correct
Question 10
1 / -0

Carrageenin is obtained from ______________.

A
Batrachospermum

B
Chondrus

C
Sargassum

D
Ulva

Solution

Carrageenin is a sulfur containing polysaccharide which is extracted from red algae or irish moss and is used as a gelling and stabilizing agent in food industries. Chondrus crispus is such a red algae. Carrageenin constitites 50% of its dry weight.
So the correct answer is "Option B".
