Question 1
1 / -0

Match the columns and choose the correct option.
$$I$$ $$II$$
$$a.$$ Green Alga $$1.$$ Dictyota
$$b.$$ Brown Alga $$2.$$ Porphyra
$$c.$$ Red Alga $$3.$$ Spirogyra

A
$$a - 3, b - 2, c - 1$$

B
$$a - 3, b - 1, c - 2$$

C
$$a - 2, b - 3, c - 1$$

D
$$a - 1, b - 2, c - 3$$

E
$$a - 1, b - 3, c - 2$$
Solution
Some commonly found green algae are Chlamydomonas, Volvox, Ulothrix, Spirogyra and Chara.
The common forms of brown algae are Ectocarpus, Dictyota, Laminaria, Sargassum and Fucus
Some members of red algae are Polysiphonia, Porphyra, Gracilaria and Gelidium.
So, the correct answer is "a−3,b−1,c−2'.
Question 2
1 / -0

Which one is a red alga?

A
Gelidium

B
Chlorella

C
Volvox

D
Ulothrix
Question 3
1 / -0

Porphyra belongs to

A
Fungi

B
Algae

C
Bacteria

D
Bryophyta
Question 4
1 / -0

Which of the following groups of algae, belongs to class Rhodophyceae?

A
Laminaria, Fucus, Porphyra, Volvox

B
Gelidium, Porphyra, Dictyota, Fucus

C
Gracilaria, Gelidium, Porphyra, Polysiphonia

D
Volvox, Spirogyra, Ulothrix, Sargassum

E
Sargassum, Laminaria, Fucus, Dictyota
Solution
The members of Rhodophyceae are commonly called red algae because of
the predominance of the red pigment, r-phycoerythrin in their body.
The common members are Polysiphonia, Porphyra, Gracilaria, and Gelidium.
While Laminaria, Fucus, Dictyota and Sargassum are brown algae.
Volvox, Spirogyra and Ulothrix are green algae.
So, the correct answer is "Gracilaria, Gelidium, Porphyra, Polysiphonia'.
Question 5
1 / -0

Identify the correct pair of combinations.
$$(i)$$ Chara - Monoecious - Chlorophyll $$a, b$$
$$(ii)$$ Salvinia - Homosporous - Free floating hydrophytes
$$(iii)$$ Ectocarpus - Filamentous form - Chlorophyll $$a, d$$
$$(iv)$$ Laminaria - Biflagellate gametes - Haplodiplontic lifecycle

A
$$(ii), (iii)$$

B
$$(i), (iv)$$

C
$$(i), (iii)$$

D
$$(iii), (iv)$$
Question 6
1 / -0

Ferns can be classified as

A
Bryophyta

B
Pteridophyta

C
Algae

D
None of the above

Solution

A fern is one of a group of about 20,000 species of plants classified in the phylum or division Pteridophyta. Thus, Option B is correct.
Question 7
1 / -0

Food reserve of phaeophyceae is

A
Laminarin and floridean starch

B
Laminarin and mannitol

C
Fat

D
Starch

Solution

The reserved food material in Phaeophyceae is Laminarin and Mannitol while the reserved food material in Rodophyceae is Floridean Starch.
So, the correct answer is 'Laminarin and mannitol'
Question 8
1 / -0

Which of the following possess rhizomes?

A
Spirogyra

B
Ferns

C
Pine

D
Cycas

Solution

Ferns of the class Polypodiopsida typically possess a rhizome that grows partially underground and deeply divided fronds and the roots grow out of the rhizome. Fronds are characteristically coiled in the bud and uncurl in a type of leaf development called circinate vernation.
So, option B is the correct option.

Question 9

1 / -0

Match and find the correct option.

	$$I$$		$$II$$
$$(a)$$	Siphonogamy and zooidogamy	$$(i)$$	Amphibians of plant kingdom
$$(b)$$	Living fossil	$$(ii)$$	Arachis
$$(c)$$	Liverworts	$$(iii)$$	Ginkgo
$$(d)$$	Double fertilization	$$(iv)$$	Cycas
		$$(v)$$	Laminaria

$$a - v, b - iv, c - i, d - ii$$

$$a - ii, b - iv, c - i, d - iii$$

$$a - iv, b - iii, c - ii, d - i$$

$$a - iv, b - iii, c - i, d - ii$$

Solution

D. a-iv, b-iii, c-i, d-ii

Reason:

Siphonogamy is the type of fertilization that takes place by the formation of the pollen tube whereas zooidogamy is the type of fertilization in which clothed male gametes participate in fertilization. Both the type of fertilization occurs in Cycas.
Gingko is known as a living fossil. These are non-flowering plants, belong to the division gingkophyta. They are the only surviving plant of this division nowadays.
Bryophytes are plants that can live in the land and water. The animals which can live inland and water are called amphibians and thus, bryophytes are referred to as amphibians in the plants. They are plants that require water for the migration of the male gametophyte to the female gamete during sexual reproduction.
Arachis is a group of flowering plants from the pea family. During fertilization, a fusion of the male and the female gamete forms the zygote which develops to form the embryo. The other male gamete fuses with the secondary nuclei to form the endosperm. Hence, it is known as double fertilization.

So the correct option is D.

Question 10
1 / -0

Vascular bundles are absent in

A
Gymnosperms

B
Angiosperms

C
Pteridophytes

D
None of the above

Solution

A vascular bundle is a part of the transport system in vascular plants. Pteridophyes, Gymnosperms and Angiosperms possess vascular tissue that helps in the conduction of water and food.
Hence the correct option is D.
