Ch. 19 Protist Ch. 25 Fungi

Zoomastigophora

Animal like flagellates

Hyaline cap

Clear space at edge of pseudopod.

Septa

Cross walls

Phylum Bacillariophyta

Diatoms- found in marine/freshwater environments. Unicellular. Geometrical shapes. With a silica-based cell wall.

Phylum Rhodophyta

Red Algae- produce toxins called terpenoids that can be used to control the growth of tumors and cancer.

Phylum Euglenophyta

Unicellular flagellated freshwater species. Mixotrophs of photosynthesis and heterotrophic

How do protists function in the environment?

can function as autotrophs, heterotrophs & decompossers.

Phylum Chlorophyta

green algae- aquatic but can be found on tree trunks, sidewalks, buildings. Examples: Spirogyra & Volvox

Foraminifera

marine protozoans that have variably shaped, colorful shells with small holes which cover one third of the sea floor.

Protists

unicellular eukaryotes

Apicomplex

Malaria-most dangerous because it has caused 1 million deaths. Caused by female anopheles mosquitoes.

Ciliates

A group of protozoans that move by waving tiny, hair-like organelles

plantlike protists

Bacillariophyta Rhodophyta Euglenophyta

Saprobes

Break down organic matter

Fungi Kingdom

Chytridiomycota Zygomycota Glomeromycota Ascomycota Basidiomycota

Three types of lichens in nature

Crustose Foliose Fructicose

Actinopoda

Endoskeleton composed of silicone dioxide, geometric, considered most beautiful organisms.

Pseudopodia

False feet

Protists are categorized by:

Fungus like Plant like Animal like

Phytomastigophora

Photosynthetic flagellates

Phylum Myxomycota

Plasmodial slime molds-exists as multi nuclear mass covered in the slime mold.

animal like protists

Protozoa

Endoplasm

Region of cytoplasm that makes up the majority of the amoeba.

Why are fungus-like organisms called decomposers?

Slime Mold- decompose dead organisms.

Acrasiomycota

Solitary amoeboid,

Gametangia

Special place in the hyphae where fungus produce gametes.

Conjugation

Spirogyra type of sexual reproduction

Protoplasm

Surrounding the cells nucleus

Thallus

The body of a lichen

Ectoplasm

The thin, clear, watery cytoplasm directly beneath the plasma membrane.

Oomycetes

Water mold-grows on dying or dead fish

Lichens

represent symbiotic relationships between a fungus and a photosynthetic partner

food vacuoles

vacuoles which store food and fuse with lysosomes that aid in food digestion.
