1 A, B, D
2 A, C, D
3 B, A, C
4 B, C, D
Explanation:
Monas has pantacronematic flagellum with two or more rows of lateral appendages on the axoneme. Lateral appendages are absent in Polytoma. Pantacronematic flagellum is found in Urceolus.

The lower most cell of filamentous algae Ulothrix is characterised by
1 Devoid of chlorophyll and enucleated
2 Presence of nucleus and non-chlorophylls
3 Presence of chlorophyll and nucleated
4 Absence of chlorophyll and enucleated
Explanation:
The lower most part of ulothrix algae is holdfast. This lower most cell of algae contain nucleus but it is a non-chlorophylls structure. Hence, the absence of chlorophyll, in the lowermost cell of ulothrix shows the beginning of labor division.

Chloroplasts of Spirogyra have:
1 spiral margin
2 smooth or waxy margin
3 smooth margin
4 none of the above
Explanation:
In Spirogyra, chloroplasts are ribbon, shaped serrated or scollped, and spirally organized. The margin of chloroplasts may be smooth or wavy or serrated. The Spirogyra chloroplasts are long, spirally coiled ribbon, smooth and may contract to form a rod structure.
