Weekly Quiz Competition

Question 1
1 / -0

Compared with the gametophytes of the bryophytes the gametophytes of vascular plant ___________________.

A
Smaller but to have larger sex organs

B
Larger but to have smaller sex organs

C
Larger and to have larger sex organs

D
Smaller and to have smaller sex organs
Question 2
1 / -0

Which of the following red algae are suitable for human consumption ?

A
Laminaria and Fucus

B
Gracilaria and Chondrus

C
Porphyra and Spirogyra

D
Rhodymenia and Porphyra.

Solution

Rhodymenia is a red alga and is well-known snack food. It has been an important source of dietary fibre throughout the centuries.
Porphyra is a cold water seaweed that grows in cold, shallow seawater. It has 30-35% proteins, 40-45% carbohydrates and a very high percentage of vitamins. The alga is sold and eaten together with rice.
So the correct answer is option D.
Question 3
1 / -0

Both pteridophytes and gymnosperms have ______________.

A
Seeds

B
Independent gametophytes

C
Archegonia

D
Ovules

Solution

Pteridophytes and certain Gymnosperms (Cycads and Conifers) have Archegonia as the female reproductive structure. It is a multicellular flask shaped structure differentiated into a broad base the venter that contains the egg and an elongated neck containing the neck canal cells, the narrow opening of the neck is covered by cover cells
So, the correct answer is 'Archegonia'
Question 4
1 / -0

Consider the following four statements whether they are correct or wrong
(A)The sporophyte in liverworts is more elaborate than that in mosses
(B)Salvinia is heterosporous
(C)The Life-cycle in all seed-bearing plants is diplontic
(D) In Pinus male and female cones are borne on different trees
The two wrong statements together are

A
Statements (A) and (C)

B
Statements(A) and (D)

C
Statements(B) and (C)

D
Statements (A) and (B)
Question 5
1 / -0

Match Column - I with Column - II and select the correct option from the codes given below.
Column - I Column - II
P. Brown algae (i) Anabaena
Q. Blue-green algae (ii) Gelidilum
R. Green algae (iii) Sargassum
S. Red algae (iv) Chlamydomonas

A
P- (ii), Q- (i), R- (iii), S- (iv)

B
P- (iii), Q- (iv), R- (ii), S- (i)

C
P- (ii), Q- (iii), R- (iv), S- (i)

D
P- (iii), Q- (i), R- (iv), S- (ii)

Solution

Anabaena:- These are the species of Blue-green algae that lives in fresh water.
Gelidium:- They are the genus of Thalloid red algae.
Sargassum:- They are the genus of brown algae with branching Thallus.
Chlamydomona:- These are the genus of single-celled Green algae having flagella for swimming.
Therefore the correct answer is option D.
Question 6
1 / -0

In a moss, the sporophyte

A
Manufactures food for itself as well as for the gametophyte

B
Arises from a spore produced from gametophyte

C
Produces gametes that give rise to gametophyte

D
None of the above

Solution

In mosses, the male gamete (sperm released from antheridia) fuses with the female gamete ( egg cells within the archegonium) to result in the immature sporophytes. The sporophyte matures and releases the spores. These spores germinate to form the protonema (an immature transitory stage), that matures into the gametophore (gamete bearing structure). Its tip branches to bear the male and the female gametophytes i.e antheridia and archegonia. So, in mosses, the gametophyte arises from spores produced from the sporophyte and the sporophyte arises from the fusion of gametes.

So, the correct answer is 'Produces gametes that give rise to gametophyte'.
Question 7
1 / -0

In mosses conducting tissue is _________.

A
Phloem

B
Parenchyma

C
Xylem

D
Coloured cells.
Question 8
1 / -0

Sporophyte is not an independent generation in _____________.

A
Bryophytes

B
Pteridopytes

C
Gymnosperms

D
Angiosperms

Solution
Question 9
1 / -0

Floridean starch as a stored photosynthate is present in

A
Chlorophyceae

B
Xanthophyceae

C
Phaeophyceae

D
Rhodophyceae

Solution

Floridean starch is found in Rhodophyta. It is more like the amylopectin which is present in the higher plants but is highly branched. The floridean starch occurs as grain outside the chloroplast in the red algal cells. This is the form in which the food in stored in the red algae.
Thus, the correct answer is option B.
Question 10
1 / -0

Sporophytic generation is borne upon gametophyte and is dependent on it. Which of the following plant exhibits this feature?

A
Marchantia

B
Lycopodium

C
Cycas

D
Zea mays

Solution

A. Marchantia is a Bryophyte. In Bryophytes, the dominant phase is represented by a free living, long lived, thalloid, haploid, nutritionally independent gametophyte to which a physically and nutritionally dependent sporophyte is attached.
B. Lycopodium is a Pteridophyte. It is a genus of clubmosses and also known as ground pine.
C. Cycas is a gymnosperm. Gymnosperms are naked seed plants.
D. Zea mays, also known as maize, is a monocot. It is an angiosperm which are the flowering plants.
So, the correct answer is 'Marchantia'.
