Phylum Sarcodina

• move by pseudopods and cytoplasmic streaming (amoeboid movement)
• reproduce by binary fission
• phagocytosis to engulf solid particles
• uses simple to diffusion to get oxygen and rid itself of waste
• eats unicellular organisms and host if parasitic
• digests using food vacuoles
• contractile vacuoles
• blob shaped
• can form cysts
• free-living and parasitic

Entamoeba histolytica

• causes amoebic dysentery
• intestinal pathogen
• from Phylum Sarcodina

Phylum Ciliophora

• binary fission and conjugation
• two nuclei (micronucleus and macronucleus)
• exchange micronucleus during conjugation
• move by cilia
• majority are free-living
• uses simple diffusion to get oxygen and rid itself of waste
• surrounded by pellicle
• form food vacuoles around food taken in at oral grove
• contractile vacuoles
• oval shaped
• food vacuoles and gullet to digest

Paramecium sp.

• member of Phylum Ciliophora
• harmless/free-living

Phylum Mastigophora

• move by flagella
• binary fission
• free-living and parasitic
• gets food by absorption
• pseudopodia elongated shape
• uses simple diffusion to get oxygen and regulated water
• eats unicellular organisms or host if parasitic
• cytoplasm digests food
•  undulating membrane

Trypanosoma sp.

• blood parasite
• causes African Sleeping Sickness
• invades nervous system
• vector: Tsetse fly
• member of Phylum Mastigophora

Phylum Sporozoa

• non-motile
• intracellular parasites
• alternate between asexual and sexual reproduction
• some form cysts
• simple diffusion

Toxoplasma gondii

• sexual reproduction in cats, asexual in humans
• toxoplasmosis causes birth defects
• member of Phylum Sporozoa

Plasmodium sp.

• causes malaria
• vector: female Anopheles mosquito
• salivary glands
• member of Phylum Sporozoa

Characteristics of Algae

• autotrophic
• reproduce sexually and asexually
• photosynthetic with chloroplasts and chlorophyll
• classified according to pigment

Phylum Chrysophyta

• golden algae
• pigment fucoxanthin masks chlorophyll
• free living
• includes diatoms which have a silicon shell

Phylum Phaeophyta

• brown algae
• olive to dark brown
• includes Giant Kelp

Phylum Rhodophyta

• red algae
• pigment phycobilians
• phytoplankton - floating communities of photoautotrophs

Phylum Chlorophyta

• green algae
• ancestors of green plants
• unicellular and multicellular
• ex: Vovlox and Spirogyra

Actinopods

• ray feet
• most plankton are in this group

Dinoflagellates

• have two flagella
• red tide creates a toxic bloom

Slime Molds

• free-living
• amoeba like organism
