Phylum porifera

PORIFERA

• 1, Water canal system_
  
  body wall encloses a cavity (spongocoel).water enters through pores (ostia) and goes out through an osculam , by the action of flagellated cells             (collar cells / choanocytes)

Animals, we can classify 11 Phyla

The kingdom Animalia we can classified into
               11 phyla (singular phylum)

* phylum- Porifera ( sponges)
* phylum- Coelenterata( gastro vascular cavitiad                                                                          animals)
* phylum- Ctenophora( sea walnuts)
* phylum- Platyhelminthes( flat worms)
* phylum- Ashelminthes(round worms)
* phylum- Annelida(segmented worms)
* phylum- Arthropoda(jointed leg animals)
* phylum- Molusca( soft boied animals)
* phylum- Echinodermata
* phylum- Hemichordata
* phylum- Chordata(modern)

Carl linnaeus's hierarchial system

Structure and some examples of caroul                 linnaeus's hierarchiel system

There are 7 obligate taxa
Species,genus,family, order, class 
Phylum/ division , kingdom

kingdom protista _ Slime Moulds

Slime moulds are saprophytic protists.the body moves along decaying twings and leaves engulfing organic_meterial . under suitable conditions , they from an aggregation called plasmodium which may grow and spread over several feet. During unfavorable conditions ,the plasmodium differentiates and form fruiting bodies . bearing spores at their tips.

The spores possess true walls.they are extremely resistance and survive for many years. Even under adverse conditions.the spores are dispersed by air currents

Hierarchial system of biological classification, carl linnaeus

Hierarchial is a biological classification . in this classification the organisms are grouped an ascending series ,comprising obligate taxa

        The most widely accepted and approved hierarchial system was introduced by carolus linnaeus . linnaeus classified organisms into 7 group in an ascending series

They are

Kingdom
Phylum/division
Class
Order
Family
Genus
Species


*The basic taxon is  species , and the higher taxon is kingdom

*Linnaeus's publication is systema naturae

Cell eukaryotic,cellwall made with chitin with nuclear envelp
Multi cellular at loose tissue  level of body organisation.

They are hetrotrophics .either saprophytic or parasytic

        Chapter 2 , Biological classification

            RH Whittacker introduced a,          phylogenetic ,biological classification in 1969 ,in this classification the organisms are grouped under Monera,Protista,Fungi,Plantae and Animalia
