Weekly Quiz Competition

Question 1
1 / -0

Which one of the following species is used for the extraction of Geranium oil?

A
Cymba paganflexuosus

B
Pelargonium groveolens

C
Rosa damascena

D
Schleichera trijuga
Question 2
1 / -0

Which one of the following structures not found in any class of algae?

A
Rhizoid and apical cell

B
Apical cell

C
Embryo

D
Thalloid plant body

Solution

C. Embryo
Reason : For most of the algal species, sperm and eggs fuse into the open water and the zygote develops into a new plant without any protection. The embryonic state is not found in them.
So the correct option is C.
Question 3
1 / -0

Match List I (Colloquial Name) with List II (Plant) and select the correctanswer using the code given below the Lists:
List I List II
A. Adder's tongues 1. Lycopodium
B. Horse tails 2. Sphagnum
C. Club moss 3. Ophioglossum
D. Bog moss 4. Equisetum

A
A-3, B-4, C-1, D-2

B
A-3, B-1, C-4, D-2

C
A-2, B-1, C-4, D-3

D
A-2, B-4, C-1, D-3
Question 4
1 / -0

Consider the following statements.
a. Ectocaipus has an alternation of isomorphic generations
b. Fucus has no free living haploid generation
c. All red algae are multicellular organisms
d. Brown algae have a few unicellular species
Which of these statements are correct?

A
$$1, 2, 3$$ and $$4$$

B
$$2, 3$$ and $$4$$

C
$$1, 3$$ and $$4$$

D
$$1$$ and $$2$$

Which one of the is a fatty acid polyester?

A
Agar

B
Lignin

C
Pectin

D
Suberin

Solution

A. Agar
Solution : The fatty acids and phosphatides of the cellular slime mold. The fatty acid composition of each of the phosphatides has been determined. Considerable molecular heterogeneity within several classes of phosphatides. The phosphatides contain an unusually high percentage of unsaturated fatty acids. Of major interest is the presence, in large amounts, of three new dienoic long chain fatty acids whose structures have been established as 5,9-hexadec- adienoic acid, 5,9-octadecadienoic acid, and 5,1 l-octadecadie- noic acid.
So, the correct answer is option A.
Question 6
1 / -0

Haploids are considered better genetic stock because they ______________.

A
Require only half of the nutrients

B
Are best for cytological studies

C
Grow better under all conditions

D
Form homozygous individuals on depolarization
Question 7
1 / -0

Which one of the following algae is reported to produce an antibiotic?

A
Nostoc

B
Ectocarpus

C
Chlamydomonas

D
Chlorella

Solution

Chlamydomonas provides antimicrobial benefit while Chlorella used for cancerous patient treatment and Ectocarpus used for molecular study only Nostoc is scientifically produces anti-biotic.
So, the correct answer is option A.

c. Absence of tracheids
d. Haploid endosperm
Which of the above are present in the case of gymnosperms?

A
$$1$$ and $$4$$

B
$$1$$ and $$3$$

C
$$1$$ and $$2$$

D
$$2$$ and $$4$$

1 / -0

Gametophyte self incompatibility does not differ from saprophytic self incompatibility in that.

A
There is co dominance of self incompatibility alleles

B
Both give $$50\%$$ functional. Pollen in pollinations on some other plants

C
There is breakdown of incompatibility on induction of polyploidy

D
There is complete failure of seed set on self pollination
Question 10
1 / -0

Which of the following pairs are correctly matched?
a. Fertile spike - Ophioglossum
b. Sporangiophore - Equisetum
c. Synangium - Psilotum
