Introduction Flashcards
type of nucleus with vegetative function
macronucleus
nucleus for reproduction
micronucleus
nucleus chromatin evenly distributed (homogenous) and present in ciliates
compact
chromatin concentrated in a single mass (endosome or nucleolus)
vesicular
carries organs of locomotion (prolongations
of the ectoplasm)
cytoplasm
regulates osmotic pressure & eliminates waste material
contractile vacuole
collect dehydrated proteins
golgi bodies
outer part (homogenous and hyaline appearance)
ectoplasm
Functions of ectoplasm
- Movement
- Food ingestion
- Excretion
- Respiration
- Protection
has role for nutrition since it contain food vacuoles, granular and pigmented
endoplasm
Modes of movement
- Cilia
- Pseudopodia
- Flagella
- Gliding
fine, short, flagella like structures present in trichomonas and balantidium
Cilia
a false feet present in entamoeba
pseudopodia
whiplike filamentous structure from a basal granule in the ectoplasm present in trypanosomes
flagella
Flagellate species
mastigophora species
Gliding movement is usually in these protozoa
Toxoplasma, Sarcocystis, Eimeria
Types of Nutrition
- Holophytic
- Holozoic
- Saprozoic
- Autotrophic
Describe the nutrition of protozoa
Incapable of utilizing inorganic material; gets
food from predigested material from the
intestinal tract, blood or lymphatics
uses micropyle (micropore) to ingest fluids/solids
eimeria
process of ingesting tissues of host through a temporary opening in the body wall
pinocytosis
pseudopodia or a cytostome are used to ingest food material from plants or animals and passed to a food vacuole
holozoic
absorb nutrients by diffusion and directly used by the organism; stored food seen inside glycogen granules
saprozoic
proteins, COH & lipids are synthesized from them
autotropic
