BROWN ALGAE
CONTENTS
 Introduction .
 Definition
 Shape
 Nutrition requirements
 Economic importance
 Reproduction
 Lifecycle stages
 Habitat
 Dispersal
 Impacts and control
 Species
INTRODUCTION :
 Brown algae include approximately 1500 speices ,
are the largest and complex of all algae .
 Mutlicellular and marine .
 Brown or olive colour to accessory pigments in the
chloroplast
 Range from simple filamentous to kelps.
INTRODUCTION :
Rich in terms of biodiversity
*Inhabiting great array of
habitats
*Critical primary producers in
pelagic and coastal environments
and in both temperate and
tropical regions around the world
SHAPE :
 Spherical and about 1/25 inch diameter .
 Consists of branched upright filaments and hairs
arising from abase of procumbent filament .
ECONOMIC IMPORTANCE :
 Food, secondary products
 Sources of alginates
Emulsifiers in everything from paint to ice cream
From kelp beds .
NUTRITIONAL REQUIREMENTS :
 from photosynthesis
 by absorbing dissolved nutrients
REPRODUCTION AND DISPERSAL :
 entirely asexually by means of spores deriving from
multi-cell sporangia
(organ containing or producing spores) with each cell
containing a single spore.
LIFECYCLE STAGES :
 The lifecycle of brown algae typically involves an
"alternation of generations" between diploid and
haploid .
LIFE CYCLE :
HABITAT :
 temperate coasts and in colder water of the
Northern Hemisphere. They inhabit the intertidal
and subtidal zones of coastal waters.
IMPACTS AND CONTROL :
Algal blooms may cause great invasion of many
species that may cause serious problems .
By eradiation technique it can be solved in right
scientific way .
BIOLOGY :
 pigments
 Chl a & c & fucoxanthin
 Cell wall
 Cellulose and mucilage
 Plant body
e.g., holdfast, stipe and blades
 Reproduction/meiosis/life history
 Most: sporic (haplodiplontic)
 One order: gametic
(diplontic)
SPECIES :
FUCUS :
