Question 1
1 / -0

What is the characteristic branching pattern of Dictyota thallus?

A
Monopodial

B
Excurrent

C
Dichotomous

D
Deliquescent

Solution

Dictyota is a ribbon shaped dichotomously branched marine brown alga that grows in shallow water. Its frond is flat and dichotomously branched.
Question 2
1 / -0

A member of Class Chlorophyceae is

A
Chlamydomonas

B
Volvox

C
Ulothrix

D
all of these

Solution

Chlorophyceae are also known as green algae. In such algae chloroplasts contain pigments like chlorophyll - a, b, carotene and xanthophyll. Their cell is made up of cellulose. Reserve food in such algae is in the form of starch. Examples are Chlamydomonas, Volvox, Ulothrix, Chlorella etc.
So, the correct answer is " All of these ".
Question 3
1 / -0

Phycoerythrin, chlorophyll a and chlorophyll d are characteristics, of

A
Phaeophyceae

B
Xanthophyceae

C
Chlorophyceae

D
Rhodophyceae

Solution

The members of Rhodophyceae are commonly called red algae because of the predominance of the red pigment r-phycoerythin in their body. Apart from this, other major pigments found in them are chlorophyll a and chlorophyll d.
Question 4
1 / -0

Read the given statements and select the correct option.
Statement 1 : Bryophytes are amphibians of plant kingdom.
Statement 2 : They live in soil but depend on water for sexual reproduction.

A
Both statements 1 and 2 are correct.

B
Statement 1 is correct but statement 2 is incorrect.

C
Statement 1 is incorrect but statement 2 is correct.

D
Both statements 1 and 2 are incorrect.
Solution
- Bryophytes are known as 'amphibians of plant kingdom' because they are adapted to land as well as water habitats.
- In their vegetative structure, bryophytes have become adapted to land.
- But they depend on water for sexual reproduction because the swimming habit is retained by their male gametes, the antherozooids.
So, the correct answer is 'Both statements 1 and 2 are correct'.
Question 5
1 / -0

Select the correct match of algal class and its characteristic flagellation.

A
Chlorophyceae - 2-8 equal, apical

B
Phaeophyceae - 2 unequal, lateral

C
Rhodophyceae - Absent

D
All of these
Solution
Chlorophyceae is a green algae which has chlorophyll a and b type. They have flagella apical and equal about two to eight in number. The reserve food material is starch.
Phaeophyceae is a brown algae which has chlorophyll a and c type. They have flagella lateral and unequal about two in number. The reserve food material is laminarin.
Rhodophyceae is a red algae which has chlorophyll a and d type. They do not have motile stage. The reserve food material is floridean starch.
So, the correct answer is option D.
Question 6
1 / -0

Bryophytes include

A
liverworts and ferns

B
mosses and ferns

C
mosses and liverworts

D
all of these

Solution

Bryophytes are divided into liverworts, hornworts and mosses. So the correct option is C.
Question 7
1 / -0

Which out of the following does not belong to brown algae?

A
Gelidium, Batrachospermum

B
Ectocarpus, Dictyota

C
Laminaria, Fucus

D
Sargassum, Ectocarpus

Solution

Batrachospermum is a freshwater red alga widely distributed in tropical, sub-tropical and temperate areas. Gelidium amansii is an economically important species of red algae commonly found in shallow cost of many East and Southeast Asian-countries.
Question 8
1 / -0

Common example of red algae is ________.

B
Sargassum

C
Ectocarpus

D
Marchantia

Batrachospermum is a

A
Red algae of sea

B
Brown algae

C
Blue algae

D
Red algae of freshwater

Solution

Batrachospermum is a family of fresh water red algae (Rhodophyta). So, the correct answer is (D).
Question 10
1 / -0

Phycoerythrin is present in

A
Euglena

B
Polysiphonia

C
Chlamydomonas

D
Fucus

Solution

Phycoerythrin is a group of red photosynthetic pigments present in red algae and some cyanobacteria. Polysiphonia is a type of red algae.
Euglena - is a group of protozoan, Chlamydomonas - is a group of green algae, Fucus - is a group of brown algae.
So, the correct answer is (B).
