- SubPhylum Apicomplexa eg Plasmodium
- SubPhylum Kinetoplastisda (mastigophora) eg Euglena, trypanosomes aka flagellata
- SubPhylum Cillophora
What are the special combination of structures of the SubPhylum Apicomplexa
Polar ring
Conoid
Supellicular
Microtubules
Micronomes
Rhoptries and
Dense Granules
What are the special structures of the SubPhylum Apicomplexa called
Apical complex
All Apicomplexes are Endoparasites true or false
True
SubPhylum Apicomplexa possess cillia or flagella
False
The apical complex are usually present in certain development stages like
Merozoites and sporozoites
The apical complex are usually present in certain development stages like
Merozoites and sporozoites
What aids the penetration of the host cells and tissue in SubPhylum Apicomplexa
Rhoptries and micronomes
Eg of SubPhylum Apicomplexa
Falciparuim
Toxoplasmo gendi
Plasmodium ovale
Sporozoites are transferred to where immediately after skin penetration
Liver
SubPhylum Kinetoplastisda or mastigophora are characterized by the possession of what
Basal body
SubPhylum Cillophora are parasitic or free living
Free living
SubPhylum Cillophora are unique with the possession of what
Binucleated cytoplasm
SubPhylum Apicomplexa is also known as
Sporozoites because they form spores during sexual and asexual reproduction
What is Chromatophores
This are cup-shaped masses of
protoplasm of a green, yellow or brownish
colour, due to the presence of the pigment
What is Chromatophores
This are cup-shaped masses of
protoplasm of a green, yellow or brownish
colour, due to the presence of the pigment:
Chlorophyll, xanthophylls, carotenes e.t.c
Classes of mastigophora
- Phytomastigophorea
These are flagellates that are plant-like in that
they possess chlorophyll
E.g Volvox, Euglena, Chlamydomonas e.t.c
- Zoomastigophora
They are animal-like and lack chromatophores
Eg of Zoomastigophora
E.g. Mastigamoeba,
Trichonymphia,
trypanosoma,
leishmania
Eg of Phytomastigophorea
Volvox, Euglena, Chlamydomonas e.t.c
This phylum constitutes the largest group of
protozoans
Phylum Ciliophora
What is Ostia
Numerous incurrent pores that perforate the body surface of a sponge, for
which they were named porifera
Ostia are linked to inhalant canals
