Answer:
4 ) marine forms are shelled with silica
Explanation:
there is no shell of silica since it is only found in the case of Diatoms, also the amoeboid protozoans body is without periplast , it may be naked or have a calcareous shell (marine).
Answer:
Option (4) Marine forms are shelled with silica, which is the wrong statement about the amoeboid protozoans.
Explanation:
An amoeboid (amoeba or amoeba) is a type of cell or organism that can change its shape, mainly by extending and retracting pseudopods. They are normally found in soil and aquatic habitats. They move using pseudopods. They usually get their food by phagocytosis.
They are unicellular, chemoheterotrophs (receiving energy from the breakdown of organic matter), have special structures for digesting food, and are capable of reproduction.
They are found in all habitats where free water is available - in freshwater, sea, and soil and sediments. The need for free water is related to the fact that active protozoa have a bare membrane through which water can easily be lost.
