My Notes
Consider the following features:
I. Chlorophyll a and Chlorophyll c
II. Fucoxanthin
III. Floridean starch
IV. Flagella 2 in number, unequal and lateral
Which of these are seen in Phaeophyceae?
(1) I, II, III
(2) I, II, IV
(3) II, III, IV
(4) I, II, III, IV
Consider the following statements regarding brown algae:
| I. | The pigments are chl a, c and xanthophylls, fucoxanthin |
| II. | Storage food is laminarin and mannitol |
| III. | The cellulosic cell wall is covered with algin |
| IV. | They have a centrally located vacuole |
| V. | Their photosynthetic organs are called as fronds - leaf like structures |
| VI. | They have pear shaped biflagellate zoospores |
| VII. | They have two unequal laterally attached flagella. |
The number of correct statements is
1. 5
2. 6
3. 7
4. 4
Which pair[s] is/are in incorrectly matched?
I. Phaeophyceae - Algin in cell wall
II. Chlorophyceae - Laminarin is stored food
III. Rhodophyceae - 2, unequal, lateral flagella
(1) Only II
(2) Only III
(3) I and II only
(4) II and III only
Asexaul reproduction by pear shaped biflagellate zoospores is seen in most:
1. Green algae
2. Brown algae
3. Red algae
4. Both (2) and (3)
Which one is a wrong statement?
(1) Archegonia are found in Bryophyta, Pteridophyta and Gymnosperms.
(2) Mucor has biflagellate zoospores.
(3) Haploid endosperm is typical feature of gymnosperm.
(4) Brown algae have chlorophyll-a and c, and fucoxanthin.
