Chlorophyta Flashcards
Halimeda sp.
Caulerpa taxifolia
Pyramimonas parkeae
Halosphaera
unicellular form
Alga showing two stages, a coccoid stage and a motile quadriflagellate stage
Pediastrum: shows a colonial organization
COENOBIA
Urospora: has an unbranched filamentous thallus
Cladophora: has a branched filamentous thallus
Among the known largest Chlorophycean cells, Valonia ventricosa or Ventricaria ventricosa, has one cell that can reach several centimeters in diameter.
This organism is frequently found on coral reefs, and a thin red alga develops on it.
V. ventricosa is able to reach high sizes and to maintain a rigid shape only thanks to the turgor pressure. Any small hole in the cell causes the organism to collapse

Ultrastructure of Chlorophyta
Chlamydomonas has cup-shaped chloroplasts
Ulothrix has parietal, girdle-shaped chloroplasts
Mougeotia has a plate-like chloroplasts
Cladophora has angular chloroplasts forming a parietal network
Pseudograna
Within the chloroplast, the thylakoids are grouped to form lamellae, consisting of a number of thylakoid varying from 2 to 6. Sometimes lamellae are stacked resembling grana, and which are therefore referred to as pseudograna.
