a line of green algae that forms colonies
Volvox
Volvox represents a line of green algae that forms colonies, apparently by means of single cells similar to those of apparently by means of single cells similar to those of
 Chlamydomonas
In some colonies, the cells are connected by
cytoplasmic strands
Volvox Reproduction
may be either asexual or sexual
what forms inside the parent colony and are released when it breaks apart
daughter colonies
Those cells resemble miniature glass apothecary bottles, complete with plugs that dissolve or "uncork," releasing the KINGDOM PROTISTA 11 protoplast inside
statospore
If the microscopic forms were larger, many surely would become collectors’ items in the art and antique shops of the world because of their exquisite form and ornamentation.
PHYLUM CHROMOPHYTA
are mostly freshwater organisms, with a few marine and terrestrial representatives,
Yellow-Green Algae
Yellow-green algae the two flagella of motile cells are oriented in
opposite directions.
brownish pigment
fucoxanthin
The brownish pigment fucoxanthin (found in other members of this phylum) is not present except in
Vaucheria, an oogamous, coenocytic, filamentous species.
commonly formed during asexual reproduction; less frequently, Zoospores are produced.
Aplanospores
Sexual reproduction is relatively rare, but when it does occur (as in Vaucheria), it may exhibit specialization, with
oogonia and antheridia
occur in the plankton of bodies of fresh water
Golden-Brown Algae
are present in some species.of Golden-Brown Algae
