Kingdom Protista
Unicellular eukaryotes
Many are both plant- and animal-like
Examples: unicellular algae and protozoans
Algae
(Kingdom Protista)Eukaryotic,
photosynthetic (chloroplasts) and mostly aquatic
Lack true stems, leaves, roots &
flowers (some have flagella)Simple reproductive
structuresReferred to as
plants
SeaweedsMulticellular algae
Aka – macrophytes
Multicellular and complex
Often classified in the Plantae Kingdom
Seaweeds have great economic importance around the world as a food source and in numerous products we use every day.
There are three types of seaweed
Draw Structure of seaweed and label
3. Red algaeMore species than other two types combined
Some involved in coral reef formation
Can grow up to 10 feet in length
DinoflagellatesUnicellular2 unequal flagellaMostly in tropical regions
Bioluminescent properties
Have an eyespotRelated to algaeAuto and heterotrophic
Algae Blooms
Gymnodinium or Red Tide
The bloom reduces oxygen levels causing fish kills
Gonyaulax also produces red tide causing paralytic shell-fish poisoning and contain a toxin saxotoxin which interferes with the nervous syst.
Invertebrates are not affected so how do humans contract it?
Algae Blooms Devastated the scallop industry in eastern
Long Island. This is an algal bloom of brown tide.
DIATOMS
Contain a green pigment called cholorophyll
In structures called chloroplasts
The cell walls are made of silica or glass so the cell wall is transparent to light
Cell structures of Diatoms
Cell wall pores- control what enters and exits the cell.
Endoplasmic reticulum- network of channels for transport of molecules
Ribosomes- place where proteins are made
Cell structures of Diatoms Mitochondria- cell’s energy factory. Sugar is
broken down into chemical energy, ATP.
Vacuole-storage structure in cells. Diatoms use it to store oil
What substance can eventually be produced from the diatom’s vacuoles by the gradual buildup over geologic time of diatomic sediment? Petroleum
Speciesunicellular, glassy
(silica shell), photosynthetic
Stores food as oil and carbohydrates
Important part of Polar water plankton
Diatom Diversity
More than 25K species Most inhabit the cold waters of the planet. What prevents them from sinking?
A. spines B. oil
Deposits of Diatomaceous Earth
Used in filtration devises
Purifying drinking water
Removing tape worms
Colon cleansing
As a Food SourceTiny invertebrates
feed on them including: Copepods Mussels Clams Oysters scallops

Cell wall composition Cellulose Silica
ForaminiferansHave shells made of calcium carbonate
Use pseudopodia to capture food
Most are bottom dwellers
Radiolarians Mostly planktonicElaborate and
delicate shells made of glass (silica)
Shells are sphericalwith radiating spinePseudopodia are
thin and needle-like
Ciliates Have hair-like cilia for locomotion and feeding
The parameciumFound mostly on seaweed and bottom sediments
Kingdom FungiEukaryotic, plant-like but without chlorophyll
Multicellular500 species of marine fungiMost unique are the lichens
LichensSymbiotic relationship with algae – lichens provide the support and the algae provide the food.
Seagrasses – Marine flowering plants, not true grasses, mostly submerged
Most related to the lily familyFound in the tropics
