Q
A

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

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.

Starch is the storage product of Chlorophyta. It is localized around pyrenoids or distributed in the chloroplast stroma.
