Protozoa Flashcards
Learn about protozoa
Protozoa are traditionally referred to as
Chemoorganotrophic protists.
A protozoan is a____________ in which all life activities are carried out within a____________
Complete organism
Single plasma membrane
Protozoans lack
Collagen and chitinous cell walls.
Protozoans are
Unicellular eukaryotes
A regular arrangement of microtubules is called
Pellicle
A regular arrangement of microtubules is called
Pellicle
The pellicle is both
Rigid and flexible
The cytoplasm of protozoan is differentiated into two regions
Ectoplasm
Endoplasm
Plantlike protists are primarily
Autotrophic
Animal-like protists are primarily
Heterotrophic
Protozoans lack collagen and chitinous cell walls. True or false
True
Microtubules is also know as
Pellicle
Pellicle is also known as
Microtubules
Protozoans reproduce both
Sexually and Asexually
The simplest and most common form of asexual reproduction is
Binary fission
Binary fission is longitudinal in
Euglenoids
Binary fission is transverse in
Ciliates
Cytokinesis means
Cytoplasmic division
Schizogony is also known as
Multiple fission
In most protozoans, sexually matured individual is
Haploid
The 7 phyla of protozoan are
Sarcomastigophora Ciliophora Apicomplexa Myxozoa Acetospora Microspora Labyrinthomorpha
Metagenomic studies grouped protozoans according to their______________
Phylogenetic relatedness
Microsporidians once considered________________ are now classified as
Amitochondriate
Fungi
Sarcomastigophora has only______ type of nucleus
One
What is or are the locomotive and feeding organelles present in phylum sarcomastigophora
Flagella or pseudopodia
The three subphylum of phylum sarcomastigophora are
Mastigophora
Sarcodina
Opalinata
Subphylum mastigophora are also called
Flagellates
Mastigophorans move by means of
One or more flagella
Mastigophorans are divided into
Phytomastigophora
Zoomastigophora
Phytoflagellates are mostly
Biflagellated chlorohyll-bearing autotrophs or mixotrophs
Example of phytoflagellates is
Euglenoids
