Which one of the following is wrongly matched?
1 Nostoc-Water blooms
2 Spirogyra-Motile gametes
3 Sargassum-Chlorophyll C
4 Basidiomycetes-Puffballs
Explanation:
Spirogyra is belong to class chlorophyceae is known as fresh water green alga the sexual reproduction in spirogyra, gametes are non-motile and sexual reproduction takes place by Conjugation. - Sargassum belongs to phaeophyceae which contains chlorophyll-a and Chlorophyll-c. - Basidiomycetes include puffballs, Mushroom etc. - Nostoc is a colonial cyanobacteria which causes algal bloom.

True statement for Ulothrix :
1 Filamentous thallus and flagellated reproductive structures
2 Branched thallus
3 Flagellated cells absent
4 None of the above
Explanation:
The thallus of ulothrix is filamentous, long, unbranched and multicellular, where the cells are arranged in a single row (i.e uniseriate). - The filamentous are bright green in colour and remain attached at one end with the substratum such as stones, rocks or some other solid object.

If you are asked to classify the various algae into distinct groups, which of the following characters you should choose ?
1 Chemical composition of the cell wall
2 Types of pigments present in the cell
3 Nature of stored food materials in the cell
4 Structural organization of thallus
Explanation:
Different types of pigment present in different group of algae. These are primarily basis of classification of algae. Most of the algal species have the same chemical composition in the cell wall and the same photosynthetic pigment. Ex:- Chlorophyll a, b, Carotenoids etc. {|c|c|c|} | {l} | |---| Classes | |pigments & Common name & Major \\ \hline Chlorophyceae & Green algae & Chlorophyll a,b \\ \hline Phaeophyceae & Brown algae & {l} |Chlorophyll a, c | |---| |Fucoxanthin \\ \hline Rhodophyceae & Red algae & {l} |Chlorophyll a,d, | |---| |r-phycoerythrin \\ \hline Cyanophyceae, & Blue green algae & {l} |Chloropyll a, | |---| |c- phycocyanin | |c- phycoerythrin \\ \hline \end{tabular}

Smallest plant which contain green pigment such as higher green plant is
1 Schizomycetes
2 Rhodophyceae
3 Chlorophyceae
4 Phaeophyceae
Explanation:
Chlorophyceae is a very significant and sizable class of green algae. Members might be filamentous, colonial, or unicellular. -The main features of the class (and most plant) are the use of starch as the principal food reserve and the green chloroplast with chlorophyll $\mathrm{a}$ and $\mathrm{b}$. - Schizomycetes is a class of unicellular or noncellular organism that lack chlorophyll, comprise all the bacteria, and are prokaryotes, although formerly classified as fungi. vRhodophyceae (red algae) is of class a marine algae, most of them red in colour, whose basic shape is filamentous or membraneous. They tend to occur at greater depths than the green algae. - Phaeophyceae - The brown algae comprising the class phaeophyceae, are a large group of multicellular algae, including many seaweeds located in cold water within the northern hemisphere
