Dinoflagellates are basically unicellular, motile and biflagellate, golden brown, photosynthetic protists. The two flagella are different (heterokont), one transverse flagellum and other longitudinal flagellum.The longitudinal flagellum is narrow, smooth, directed posteriorly and lies in the sulcys. The transverse flagellum is ribbon-like and lies in the cingulum or annulus. The two types of flagella beat in different directions. A well defined nucleus is present, which has been named as mesokaryon.

The features described in the slide under the microscope - unicellularity, well-defined nucleus, and biflagellate nature - can help us identify the organism as a dinoflagellate. Let's break down the features and understand why the correct answer is option 'D'.
1. Unicellularity:
Unicellularity refers to the organism being composed of a single cell. In this case, the slide shows a single cell, indicating that the organism is not multicellular.
2. Well-defined nucleus:
A well-defined nucleus means that the cell has a distinct and clearly visible nucleus. The nucleus is a membrane-bound organelle that contains the genetic material of the cell. In the slide, the presence of a visible nucleus suggests that the organism belongs to the domain Eukarya, which includes organisms with well-defined nuclei.
3. Biflagellate:
Biflagellate means that the organism possesses two flagella. Flagella are whip-like appendages that help with cell movement. In this case, the slide shows one flagellum lying longitudinally (along the length of the cell) and another flagellum lying transversely (across the cell). This unique arrangement of flagella is characteristic of dinoflagellates.
Dinoflagellates are a group of eukaryotic microorganisms that belong to the phylum Dinoflagellata. They are typically found in marine and freshwater environments. Dinoflagellates are known for their diverse forms and ecological roles. Some are photosynthetic, producing their own food through photosynthesis, while others are heterotrophic, consuming other organisms. They play crucial roles in marine ecosystems as primary producers and as a food source for other organisms.
In summary, based on the features described in the slide under the microscope - unicellularity, well-defined nucleus, and biflagellate nature - the organism can be identified as a dinoflagellate (option 'D').
