Phylum Porifera contains about 5,000 living species of sponges. Sponges are the most primitive of all animals and exist in three main groups - Hexactinellida, Demospongia, and Calcarea. Sponges feed by filtering water through their outer walls to intake bacteria and remove waste, though they are generally non-motile. They can reproduce both sexually, releasing sperm to fertilize females of the same species, and asexually through budding.

Sponges are the simplest multicellular animals and lack tissues and organs. They live in aquatic environments and have a porous body with water circulating through it. Sponges are divided into three classes - Calcarea, Hexactinellida, and Demospongiae - based on the material that makes up their skeletons. Their basic body structure includes pores for water intake, chambers for filtering and digestion, and an opening for water outflow. Sponges play an important ecological role as filter feeders.

Phylum Porifera: The Pore Bearing Animals
Phylum Porifera includes sponges, the simplest multicellular animals. They live in both freshwater and marine environments and have no true tissues. Their bodies are composed of totipotent cells and a skeleton made of silica or calcium carbonate spicules. Sponges filter feed using flagellated cells and circulate water through their porous bodies via an aquiferous system. They reproduce both sexually through external fertilization and asexually by budding or gemmules. Many species have symbiotic relationships with bacteria and algae. Sponges provide important habitat and are a source of bioactive compounds used in human pharmaceuticals to treat diseases.
Presentation on porifera
This presentation provides an overview of Porifera (sponges). It discusses their classification, features, canal systems, and examples from different classes. The key points are:
- Porifera are multicellular, sessile marine organisms with a diploblastic body plan and canal system for water flow. Their bodies have pores, canals, and choanocyte cells.
- Phylum Porifera is divided into 3 main classes based on skeleton composition: Calcarea have calcium carbonate spicules; Hexactinellida have silica spicules; and Demospongiae have smaller triaxon and six-rayed spicules.
- The syconoid canal system of scypha
9. Phylum Porifera Notes
Phylum Porifera includes about 5,000 living species of sponges. There are three main classes: Hexactinellida (glass sponges), Demospongia (most diverse class making up 90% of species), and Calcarea (found in shallow waters with calcium carbonate spicules). Sponges are the most primitive multicellular animals and feed by filtering water through their outer walls using flagella and contractile cells to pump water in and out for feeding, waste removal, and oxygen intake. They reproduce both sexually and asexually.
Phylum porifera,coelentrata , platyhelminthes
Sponges are the most primitive multicellular animals, belonging to phylum Porifera. There are over 7,000 sponge species, most of which are marine. Sponges are sessile filter feeders that live in shallow waters and vary in size and shape. They lack tissues and organs. The three classes of sponges are Calcarea, Demospongiae, and Hexactinellida, which differ in the material that makes up their skeleton structures called spicules. Sponges reproduce both sexually and asexually.
Lab 3 & 4 porifera & cnidaria
The document summarizes two phyla - Porifera (sponges) and Cnidaria (jellyfish, corals, anemones, hydras). It describes their key characteristics, structures, taxonomy, and life cycles. Sponges are the simplest multicellular organisms with no tissues; they have skeletal structures like spicules. Cnidarians have stinging cells called nematocysts and a sac-like body plan. Their life cycles may involve both asexual polyp and sexual medusa stages. The phyla are divided into classes based on their structural and morphological features.

Sponges are primitive filter feeders that pump water through their bodies to feed on bacteria, and can reproduce both sexually and asexually. They have no tissues or organs, with individual cell types performing specific functions. The skeleton is made of either spicules like silica or calcium carbonate, or a protein mesh called spongin.
Sponges
The document discusses the characteristics of sponges. It notes that sponges are the simplest of animals, with no organs or senses. However, they are classified as animals because they are multicellular, their cells have specialized functions and lack cell walls, they are heterotrophic, and their larvae are motile. The document describes sponges' anatomy, noting they are filter feeders that draw water through pores using flagella. It also discusses sponge spicules, which form their skeleton, and their reproduction, which can occur asexually and sexually through budding.
Phylum Porifera
This document summarizes key aspects of the phylum Porifera (sponges). It describes their multicellular origins, body structures, cell types, skeleton formation, water circulation, feeding, reproduction, development, and classification. The four classes of sponges - Hexactinellida, Calcarea, Demospongiae, and Sclerospongiae - are introduced along with examples.
Phylum Porifera
Sponges are multicellular invertebrates that live in marine and fresh waters. They have radial symmetry or are asymmetrical and lack cell specialization. Sponges intake water through pores called ostia which flows through canals to chambers called spongocoels and exits through larger openings called oscula. They filter feed by trapping bacteria and other food particles but lack nervous, digestive and circulatory systems. Reproduction can occur sexually as hermaphrodites or dioeciously. There are three main groups of sponges: Hexactinellida, Demospongia and Calcarea.
Phylum Porifera - Sycon
The invertebrates, or invertebrates, are animals that do not contain bony structures, such as the cranium and vertebrae. The simplest of all the invertebrates are the Parazoans, which include only the phylum Porifera: the sponges.
Parazoans (“beside animals”) do not display tissue-level organization, although they do have specialized cells that perform specific functions. Sponge larvae are able to swim; however, adults are non-motile and spend their life attached to a substratum.
Since water is vital to sponges for excretion, feeding, and gas exchange, their body structure facilitates the movement of water through the sponge. Structures such as canals, chambers, and cavities enable water to move through the sponge to nearly all body cells.
Poriferans and Placozoans
This document summarizes key characteristics of poriferans (sponges) and placozoans. Sponges have choanocytes that capture food through phagocytosis and lack nerves and true musculature. They have an endoskeleton of mesohyl or spicules and spongin. Placozoans are simple multicellular organisms with two epithelial cell layers, glide using cilia or change shape, and digest food extracellularly. Both groups reproduce asexually through budding or fragmentation and sexually.
Phylum Porifera
This document provides information on the phylum Porifera (sponges). It discusses their key characteristics, including being multicellular organisms with cells not organized into tissues. Their bodies have epidermis, mesenchyme, and choanocytes. Sponges come in three basic body forms: asconoid, syconoid, and leuconoid. Their skeletons contain spicules made of silica, calcite or spongin. Specialized cell types perform functions like pinacocytes, choanocytes, amoebocytes and sclerocytes. The document outlines sponge morphology and anatomy in detail across multiple pages.
Porifera.Ppt
Porifera, also known as sponges, are considered the oldest of animal phyla. As a sponge, it can filter its entire body weight of water in under a minute using a system of pores and canals, and lives wherever there is water. Sponges are multicellular but lack tissues, and reproduce both sexually and asexually. It seeks a soulmate who enjoys slowing down to appreciate life.

1) Sponges are simple aquatic animals that live in seas and freshwater. They are filter feeders and lack true tissues, organs or systems.
2) Cnidarians are carnivorous aquatic animals that have specialized stinging cells called cnidocytes. Many live as polyps or jellyfish and reproduce sexually or asexually.
3) Plathyhelminthes include parasitic flukes that attach to hosts with suckers to feed, as well as free-living planaria that crawl along pond bottoms as carnivores.
Coral taxonomy
This document provides information on the taxonomy of corals. It begins by introducing the phylum Cnidaria, which includes corals. It then describes key characteristics of Cnidaria and provides a classification system, dividing the phylum into four classes: Hydrozoa, Scyphozoa, Anthozoa, and Cubozoa. Most of the document focuses on describing the class Anthozoa, which contains corals and is further divided into subclasses and orders. For each group, example genera are provided. Key characteristics and taxonomic groups of important soft coral orders are also summarized.
Soft corals & their ecology
Soft corals produce a flexible skeleton composed of small calcium carbonate structures called sclerites. They have 8 tentacles and live in colonies. Their skeleton is smaller and contains more protein than hard corals. They come in many shapes and colors and play an important role in reef ecosystems by providing habitat for other organisms. Soft corals reproduce both sexually through broadcast spawning and larval development, and asexually through budding and fragmentation.

THE AMAZING WORLD OF INVERTEBRATES
Invertebrates are animals without backbones. They make up 97% of the animal kingdom and can be found in water and other environments. They exhibit various symmetries and belong to phyla like porifera, cnidaria, platyhelminths, and arthropods. Paramecium are single-celled protozoans that move using cilia, feed by ingesting bacteria and algae, and reproduce through binary fission. Sponges are filter-feeding aquatic animals with pores, skeletal elements, and multiple cell types including choanocytes. Cnidarians like jellyfish have stinging cells and a diploblastic structure, with many exhibiting a complex life cycle involving polyps and medusae

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
