Answer 1

PROTOZOANS
Examples. amoeba, euglena, plasmodium
-They are unicellular
-They have no germ layers
-They are at the protoplasmic level of organisation(they don’t have special tissues and organs but they have organelles)
-They are mostly microscopic, some are colonial
-They exhibit bilateral and radial symmetry
-They They have variable shapes. Some are round, elongated, etc
-They are found everywhere(wherever life exists)

Question 2

Characteristics Of Protozoans

-Some are … and some are ….
-Protozoans exhibit all types of …
Some …. their food themselves by … e.g. …
Some are …. like …. and ….
-Protozoans reproduce asexually by … or ….

The most common reproduction is by ….

Answer 2

-They are very adaptable, easily distributed
-They can be found in marine water, fresh water, soil or decaying matter
-Some are symbiotic or commensals
-Some are motile and some are stationary
-Protozoans exhibit all types of nutrition. Some manufacture their food themselves by photosynthesis e.g. euglena. Some are heterotrophs like amoeba and paramecium
-Protozoans reproduce asexually by binary fission or budding

The most common reproduction is by Binary Fission
