euglena

minute single-celled green freshwater organism having a single flagella

cyst

thick-walled, closed sac or pouch containing fluid or semisolid material., A young worm with a protective covering.

kind

phylo

conjugation

form of sexual reproduction in which paramecia and some prokaryotes exchange genetic information

contractile vacuole

saclike organelles that expand to collect excess water and contract to squeeze the water out of the cell

heterogamete

gamete that differs in size and shape

agar

another polysaccharide that comes from the cell walls of red algae

Chlorophyta

[plant-like] Green algae; unicellular. Photosynthetic. Most have flagella @ a point in life. Store food as starch.

zoospore

an asexual spore of some algae and fungi that moves by means of flagella

Malaria

an infective disease caused by sporozoan parasites that are transmitted through the bite of an infected Anopheles mosquito

Plantae

the taxonomic kingdom comprising all living or extinct plants

Sporozoa

strictly parasitic protozoans that are usually immobile

kingdom

one of seven biological categories: Monera or Protoctista or Plantae or Fungi or Animalia

genus

(biology) taxonomic group containing one or more species

pseudopod

A temporary, foot-like extension of a cell, used for locomotion or engulfing food

taxonomy

(biology) study of the general principles of scientific classification

natural selection

a natural process resulting in the evolution of organisms best adapted to the environment

oral groove

A funnel-like structure used by ciliates for feeding.

ectoplasm

the outer granule-free layer of cytoplasm

holdfasts

take the place of roots and anchor the plants to the ocean floor

diatom

microscopic unicellular marine or freshwater colonial alga having cell walls impregnated with silica

pyrenoid

an organelle that synthesizes and stores starch

a tiny cell that is able to grow into a new organism

Latin

Language used for scientific names

adaption

inherited characteristic that increases an organisms chance of survival

mouth pore

in protozoa, an opening into which the oral groove opens

endoplasm

The dense cytoplasm found in the interior of many cells

fragmentation

a type of asexual reproduction where a septate hypha dries and shatters, releasing individual cells that act as spores, A means of asexual reproduction whereby a single parent breaks into parts that regenerate into whole new individuals.
