Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How do phylum sporozoa move?
A
they move using flagella
B
they move from pseudopods (false feet)
C
They have hairlike projections to propel them towards food
D
they have no special structures for locomotion
Explanation: 

Detailed explanation-1: -Locomotion-Most of the protozoa species have flagella, cilia or pseudopodia. Sporozoa, which don’t have any locomotory structure, have subpellicular microtubules, which help in the slow movement.

Detailed explanation-2: -Unlike the crawling movement of amoebae and vertebrate fibroblasts, sporozoon protozoa are characterized by a ‘gliding movement’ in which no obvious changes occur in cell shape.

Detailed explanation-3: -4. Sporozoans (Sporozoa) – animal-like protists that can’t move on their own & are parasitic, ex : Plasmodium causes malaria. mosquito. non-motile.

Detailed explanation-4: -The distinguishing features between the groups was based on motility (i.e., ameboid, flagella, cilia). The sporozoa were a heterogeneous group that produced spores during one stage of their life cycles and exhibited a ‘gliding’ motility.

Detailed explanation-5: -Sporozoa is a large group of parasites and are non-photosynthetic protists. The flagellated stage is completely absent in them. Hence they do not bear any locomotory organ.
