If the characteristics of an organism is unicellular without the cell wall, the cell contains a golgi body and ribosomes and ingests food via phagocytosis. Identify the kingdom of this organism.
The organisms in kingdom Protista are considered as most primitive organisms. These are eukaryotic organisms usually without a cell wall. Ribosomes are present in protists cell hence help in protein synthesis, and Golgi body helps in folding and sorting these proteins. The food ingestion happens via phagocytosis wherein the plasma membrane of cell helps in engulfing the food particle.
The correct answer is D.
