Answer 1

Answer:

The correct answer is: Ciliate.

Explanation:

• Ciliate can be defined as single-celled eukaryotic organism belonging to the Taxonomic Phylum Protozoa.
• They possess small but motile extensions of the cytoplasm called the Cilia. The Cilia help in their movement.
• They possess two nucleus.
• The larger nucleus, also called the vegetative nucleus, is polyploid in nature and helps the cell to regulate its metabolism and phenotype.
• The smaller nucleus, also called the generative nucleus, is diploid in nature, contains the genome and is responsible for transmitting information to the next generation.
• Other organelles in the cells are well developed.
• An essential organelle is the Contractile Vacuole which is capable of maintaining the osmotic pressure in the cell by ejecting excess water out of the cell.
