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. | The protoplast 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

| 4. | Brown algae have chlorophyll-a and c, and fucoxanthin. |
Which of the following groups of algae produces algin?
| 1. | Phaeophyceae and Chlorophyceae |
| 2. | Rhodophyceae and Phaeophyceae |
| 3. | Chlorophyceae and Rhodophyceae |
