Weekly Quiz Competition

Question 1
1 / -0

Which of the following is a diploid?

A
Capsule of moss

B
Gametophyte. archegonia and egg of moss

C
Gametophyte, antheridia and sperm of moss

D
Gametophyte and spore of moss

Solution

Mosses have neither pollen nor flowers and rely on water to carry the male gametes (the sperm) to the female gametes (the eggs). The spore capsules are produced after the sperms have fertilized the eggs. As they are produced after fertilisation, these spore capsules are diploid.
So, the correct option is 'Capsule of moss'.
Question 2
1 / -0

Match column I with column II and select the correct option from the codes given below.
Column I Column II
A. Artificial system of classification (i) Bentham and Hooker
B. Natural system of classification (ii) Linnaeus
C. Phylogenetic system of classification (iii) Engler and Prantl

A
A-(ii), B-(i), C-(iii)

B
A-(i), B-(ii), C-(iii)

C
A-(iii), B-(ii), C-(i)

D
A-(iii), B-(i), C-(ii)
Solution
- Artificial system: It was proposed by Carolus Linnaeus, known as the father of systematic botany ". Classification without basing on the relationship among plants.
- Natural system: George Bentham and Joseph Dalton Hooker proposed this system of classification. Here classification is based on the form or natural relationship between plants.
- Phylogenetic system: This system contains fourteen major divisions. It is to be understood that the monocots are primitive than the dicots.
- So,the correct answer is " (A) - (ii),(B) - (i),(C) - (iii) ".
Question 3
1 / -0

Laminarin and mannitol, the reserve food of brown algae, are

A
lipids

B
complex carbohydrates

C
proteins

D
lipoproteins

Solution

The food in the members of Phaeophyceae is stored as complex carbohydrates in the form of laminarin or mannitol.
Question 4
1 / -0

Which of the following statements about Phaeophyceae is correct?

A
Vegetative reproduction occurs by fragmentation.

B
Asexual reproduction is by biflagellate pear-shaped zoospores.

C
In sexual reproduction, gametes are pyriform and bear 2 laterally attached flagella.

D
All are correct.
Solution
- Vegetative reproduction takes place by fragmentation. First propagules are developed and then after detachment new plants are formed.
- Asexual reproduction takes place by biflagellate pear-shaped zoospores.
- Sexual reproduction ranges from isogamy to oogamy through anisogamy. Gametes al bears 2 laterally attached flagella.
- In most of the members, fertilization is external.
- So, the correct answer is option D.
Question 5
1 / -0

Agar-agar is commercially obtained from ______.

A
Green algae

B
Blue-green algae

C
Brown algae

D
Red algae
Question 6
1 / -0

Read the given statements about algae and select the correct option.
(i) Plant body is thalloid.
(ii) They are largely aquatic.
(iii) Reproduction occurs by vegetative, asexual and sexual methods.
(iv) Chlamydomonas, Volvox and Ulothrix are the multicellular algae.

A
Statements (i) and (ii) are true

B
Statements (ii) and (iii) are true

C
Statements (i), (ii) and (iii) are true

D
All statements are true

Solution

Algae are usually aquatic, either marine or fresh water. Only a few algae occur in moist terrestrial habitats like tree trunks, wet rocks, moist soil, etc. Plant body is thallus (a form without any differentiation into root, stem and leaves). Sexual, asexual and vegetative modes of reproduction are | abundant. Form and size of algae range from microscopic unicellular forms like Chlamydomonas, to colonial forms like Volvox and to filamentous forms like Ulothrix and Spirogyra. So, the correct answer is 'Statements (i), (ii) and (iii) are true'.
Question 7
1 / -0

Major photosynthetic pigments in green algae are

A
Chl $$a$$ and $$b$$

B
Chl $$a$$, $$c$$ and fucoxanthin

C
Chl $$a$$, $$d$$ and phycoerythrin

D
Chl $$a$$ and $$c$$

Solution

A. Chl a and b
Solution : Most important chlorophyll is chlorophyll a which makes photosynthesis possible. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll a. Another kind of chlorophyll is chlorophyll b which occurs only in plants and green algae.
So the correct answer is "Chl a and b".
Question 8
1 / -0

Green algae usually have a rigid cell wall made of an inner layer of ______ and an outer layer of _____.

A
cellulose, cellulose

B
pectose, pectose

C
pectose, cellulose

D
cellulose, pectose

Solution

Cell wall of green algae is thin, transparent and firm and consists of outer pectic and inner cellulosic layers. It is smooth but in most of species it gets thickened at the anterior end to form an apical papilla.
Question 9
1 / -0

Which type of sexual reproduction is found in volvox?

A
Isogamous

B
Anisogamous

C
Oogamous

D
All of these

Solution

Volvox is the fresh water green algae that grows on the surface of water bodies. During rainy seasons, they grow fast making the surface to appear in green color. Volvox reproduces both sexually and asexually. The sexual reproduction type is Oogamous type
Question 10
1 / -0

In most green algae, pyrenoids, the storage bodies, are located in_________,

A
chloroplasts

B
mitochondria

C
cytoplasm

D
nucleus

Solution

Pyrenoids are cellular micro-compartments that are not membrane bound organelles. Pyrenoids are found within chloroplast. Chloroplasts generally contain one to many pyrenoids for storage of starch.
