Answer:
absent
Explanation:
Cytological structure of all the above options revealed that they lack flagella.
Red alga is eukaryotic without flagella, centrioles, with phycobiliproteins and chloroplast lacking external endoplasmic reticulum and unstacked thyllakoid.
Cyanobacteria do not have organs for movement such as flagella, but some filamentous BGA exhibit gliding movement due to slime secretion along with contractile waves in the cells.
In case of higher seed plants (Spermatophyta) like gymnosperm and angiosperm, flagella are absent since, presence of pollen grain eliminated use of water for fertilization.
