5. Green Algae: Phylum Chlorophyta
• Chlorophyll in both green algae and plants
are not normally masked by other
pigments
• Land plants are believed to have evolved
from green algae; considered by many
taxonomists as belonging to Kingdom
Plantae!
8. Distinguishing among classes
based on:
1.How flagella are
attached/constructed:
•basal bodies orientation
•microtubule roots
2.Cell covering:
•scales vs. cell wall
3.How cells divide:
•aspects of mitosis and cytokinesis

17. 1. Prasinophyceae = primarily marine
flagellates, some freshwater; modern
representatives of earliest green algae
2. Ulvophyceae = marine macroalgae
3. Chlorophyceae = freshwater
4. Charophyceae = freshwater; all
terrestrial plants are derived from
Charophycean class
18. Prasinophyceae
Morphology:
- unicellular, free-living, primitive green
flagellates
- 1-8 flagella of varied morphology
- flagella usually inserted in a lateral or
apical depression
Habitat:
- marine and freshwater habitats
- important part of phytoplankton
(picoplankton)
19. Special features:
- organic scales on flagella and plasmalemma
- fossil findings ~ 1.2 billion years old
(Precambrium)
Cell division:
- open or closed mitosis
- persistent or non-persistent telophase
spindle
- cytokinesis by cleavage furrow or
phycoplast
Prominent species:
- Tetraselmis, Pyramimonas, Ostreococcus
