3. OVERVIEW Green Pigment called Chlorophyll for photosynthesis Motile
ALGAE
Debate about if they should be in the plant kingdom

5. CHLOROPHYLL and ACCESSORY PIGMENTS
Light is trapped by Chlorophyll and accessory pigments
Chlorophyll a – the most effective
Chlorophyll b and c absorb other wavelengths of light
Accessory Pigments – capture light at other wavelengths than chlorophyll

7. EUGLENOPHYTA 1,000 species Unicellular flagellated euglenoids
Can be heterotrophic absorbing decaying matter
Chlorophyll and photosynthetic – plant like
No cell wall and two flagella and pellicle (cell membrane that is folded like a ribbon
Freshwater, crawl through mud
Asexual reproduction with binary fission
Eyespot – reddish pigments to find sunlight

9. CHRYSOPHYTA 850 species Golden algae (yellow-green) Freshwater
Cysts are formed to survive unfavorable conditions
Two flagella, pectin in cell walls and sometimes cellulose as well
Shade of yellow of brown carotenoids
Store energy as oil and help in petroleum formations

11. DIATOMS - BACILLARIOPHYTA
11,500 species
Freshwater and Marine
Shells or Valve made of silicon dioxide
Centric diatoms – circular shells
Pennate diatoms – rectangular shells
Phytoplankton – release oxygen
Diatomaceous earth - shells and is used in detergents, paint remover, fertilizers, insulators and some toothpaste

13. PYRROPHYTA - DINOFLAGELLATES
1,100 species
Unicellular
½ Photosynthetic and 1/2 heterotrophic
Yellowish green to brown color
Two flagella
Made of cellulose
Bioluminescence – light – Fire Plant
Color producing toxins – red tide
This is what makes them dangerous to humans, oysters and such eat them and then we eat them

15. ECOLOGY Base of the food chain
Phytoplankton = surface of ocean living organisms, food source
Algal Blooms = sewage is a great food source, grow in population and deplete the nutrients, can be toxin producing (red tide)
