order, 8 belonging
seaweed and 7 to
Enteromorpha.
• And ecology of the order
Ulvales occuring along
the coast of Pakistan.
• Pakistani coastal area is
rich in algal diversity and
biomass because of warm
climate and

5. Jolyna laminarioides
• The plants consist of one to several
erect blades arising from a discoid
holdfast.
• Anatomical features include a
meristoderm, an outer and inner
cortex, a transition region, a medulla
that is composed of elongated cells
and a ground tissue made of a dense,
irregular interconnected filaments.
each cell contain single chlorophyll.
• Also found in coastal areas near
Karachi-Pakistan,
6. Sargassum
• Sargassum was founded during
January 1997 and July 2002 from
coastal areas near sea -Pakistan, dried
powdered. From ashes of lower,
middle and upper parts of their
elements. 11 elements were
quantitatively estimated.
• Sargassum occurs naturally on
beaches, albeit in smaller quantities.
Sand dune plants need nutrients from
the Sargassum and sea birds, for
example, depend on the sea life
carried in the sargassum for food.

7. Green sea weeds
• Elements such as Co, Cr, Cu,
Fe, K, Mg, Na, and Zn were
determined quantitatively. and,
K, Mg, and Na were in highest
proportion in the investigated
red seaweeds.
• different species of seaweeds
were collected from Karachi
coast.
• and several biological tests
conducted on them in order to
investigate their antibacterial,
antifungal, phytotoxic and

8. Asparagopsis taxiformis ,Stoechospermum
polypodioides ,Caulerpa, Gracilaria
• Twenty two species of seaweeds viz.,
Asparagopsis taxiformis collected from
the coastal areas Manora, Paradise
Point of Pakistan.
• Stoechospermum polypodioides
appeared to be the most active seaweed
as it caused 80 % mortality of the
nematode larvae after 72 h exposure to
its extract
