There is a gelatinous, non-cellular mesoglea, in between these two layers. This contains many free amoeboid cells.The body has many pores called the ostia and a single large opening called osculum at the top.Spongocoel is the body cavity that is present. • They have the characteristic canal system for the flow of water through the body. • Sense organs are absent.There is an endoskeleton present with calcareous spicules (calcium carbonate) or siliceous spicules (silica) or sponging fibres (protein).Sexes are not separate. • Asexual reproduction is seen through budding, fragmentation. Sexual reproduction is seen in certain species, through gametic fusion. • #porifera #Sponges#SpongeAnatomy#PoriferaInternalStructure#SpongeTissues#Choanocytes • #Spongin#Spicules#PoriferaCanals#SpongeCellTypes#PoriferanReproduction#SpongeSkeleton • #Osculum#PoriferaBodyPlan#SpongeHistology#SpongeCellLayers#SpongePores • #Amoebocytes#PoriferaGrowth#SpongeCavity#SpongeNutrition#PoriferanDevelopment • #sycon#scypha#spongilla#freshwatersponge#euspongia#bathsponge#cliona#leucosolenia • #euplectella • #biologyncert #NCERTBiology #NCERTClassXIBiology #NCERTClassXIIBiology #NCERTBiologyTextbook #NCERTBiologySyllabus #BiologyCBSE #BiologyEducation #BiologyTextbook #NCERTStudyMaterial #biologyexamprep • #UPSC#UPSCPreparation#UPSCBiology#UPSCBioScience#UPSCLifeSciences • #UPSCOptionalBiology#UPSCexam#UPSCAspirants#UPSCSuccess#UPSCMains • #UPSCPrelims #UPSCCoaching • #Biology #LifeScience #BiologyFacts #BiologyEducation #Science #BiologyTopics #BiologyExploration #BiologyStudy #BiologyKnowledge #BiologyFun #BiologyLovers #BiologyFacts • #NCERT #NCERTBooks #NCERTSyllabus #NCERTStudyMaterial #NCERTPublications #NCERTResources #NCERTTextbooks #CBSE #CBSESyllabus #Education #StudyMaterial #AcademicResources #SchoolEducation #NCERTExams #NCERTPreparation • #CBSE #CentralBoardOfSecondaryEducation #CBSESyllabus #CBSEBoard #CBSEExams #CBSEPreparation #CBSECurriculum #CBSEStudents #CBSEEducation #CBSEStudy #CBSEOnline • #NEET #NEETExam #NEETPreparation #NEET2023 #NEETAspirants #NEETStudy #NEETEntrance #MedicalEntrance #NEETExamPrep #NEETSyllabus #NEETOnlineCoaching #NEETGuidance #NEETStudyMaterial #NEETQuestions #Zoology ZoologyTopics • PYQ :- • PYQ's Digestion and Absorption • Reproduction in Flowering Plant :- • SEXUAL REPRODUCTION IN ANGIOSPERM - ... • Human Reproduction :- • HUMAN REPRODUCTION -CLASS -12th - PAR... • Human Reproduction NCERT DISCUSSION :- • HUMAN REPRODUCTION-NCERT DISCUSSION-P... • Reproductive Health :- • REPRODUCTIVE HEALTH - PART -1- INTROD... • • Principles of Inheritance and Variation :- • Introduction To Mendelian Genetics | ... • Molecular Basis of Inheritance :- • Introduction - Nucleic Acid | Molecul... • Biotechnology and Its Application : - • Biotechnology and Its Application | C... • Biotechnology Principle and Processes :- • Biotechnology Principles and Processe... • Animal Kingdom :- • Basis of Classification | Animal King...
