A. Amoeba , Euglena and Diatoms
B. Amoeba , Euglena and Penicillium
C. Amoeba , Spirogyra and Penicillium
D. Euglena , Spirogyra and Penicillium

Answer 1

Protista belongs to species which are aquatic and it does not contain any boundaries. It has a thin cell membrane just to provide protection from the external world. They have long cylindrical structures like the body. In classifications of biology- R.H Whittaker proposed five kingdom and six kingdom classifications. Kingdom classifications are an important aspect to identify each and every organism belonging to each species. The five kingdom classification includes- plantae, animalia, fungi, Protista and bacteria.

Complete answer-
Option A Amoeba , Euglena and Diatoms- Amoeba , Euglena and diatoms, and paramecium. These are the organisms which fall into the category of Protista.
Option A is the correct answer.
Option B Amoeba , Euglena and Penicillium - Amoeba and Euglena are considered as Protista but Penicillium notatum and others are bacteria.
Option B is not the correct answer.
Option C Amoeba , Spirogyra and Penicillium - Amoeba is Protist but Spirogyra and Penicillium are Monerans.
Option C is not the correct answer.
Option D Euglena , Spirogyra and Penicillium - Euglena are the only Protists here in the option and the rest of the organisms are bacteria, so this is incorrect.
Option D is not the correct answer.

Hence, option A is the correct answer

Note:
As we discussed about protists classification, other organisms are also abundant. Bacteria are the most abundant microorganisms. Bacteria occur almost everywhere. It is the most easily found organism on earth. Bacteria are classified on the basis of morphology and shape. The spherical is called coccus, rod shaped is bacilli, spiral shaped is called spirillum.
