Which of the following pairs is incorrectly matched?
1 Chlorophyceae - Major pigments are chl a and $b$.
2 Phaeophyceae - Cell wall is made up of cellulose and algin.
3 Rhodophyceae - Stored food is mannitol.
4 Chlorophyceae - Cell wall is made up of cellulose.
Explanation:
(c) Rhodophyceae is red algae in which food is stored as floridean starch which is very similar to amylopectin and glycogen in structure.

A student was given a sample to observe under the microscope. He observed and found that the sample is the most common type of spore involved in asexual reproduction in algae. Identify the spore.
1 Zoospore
2 Endospore
3 Hypnospore
4 None of these
Explanation:
(a) Asexual reproduction (in algae) is by the production of different types of spores, and the most common type is zoospore. Zoospores are flagellated (motile) and on germination give rise to new plants.

In class phaeophyceae, the plant body is usually attached to the substratum by $a$ stalk, the B_ and leaf like photosynthetic organ-the $\underline{\text{ }\!\!~\!\!\text{ c }\!\!~\!\!\text{ }}$.
1 A-holdfast, B-stipe, C - frond
2 A - stipe, B - holdfast, C - frond
3 A-frond, B - stipe, C-holdfast
4 A - stipe, B - frond, C - holdfast
Explanation:
(a) In class phaeophyceae, the plant body is usually attached to the substratum by a holdfast $\left( A \right)$, and has a stalk, the stipe(b)and leaf like photosynthetic organ - the frond $\left( C \right)$.
