Sponge body diagram
Sponges constitute the phylum Porifera, and have been defined as sessile metazoans (multicelled immobile animals) that have water intake and outlet openings connected by chambers lined with
choanocytes, cells with whip-like flagella. However, a few carnivorous sponges have lost these water flow systems and the choanocytes. All known living sponges can remold their bodies, as most types of A sponge is a member of the phylum Porifera.It is a simple animal with many cells, but no mouth, muscles, heart or brain.It is sessile: it cannot move from place to place the way most other animals can.A sponge is an animal that grows in one spot like most plants do. Nevertheless, sponges are quite successful. The basic body plan is a jelly-like layer sandwiched between two thin layers of cells. The three groups of tissues, the two cavernosa
and the spongiosum, are expandable, sponge-like structures involved in the process of a penile erection. Insect morphology is the study and description of the physical form of insects.The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insects from other arthropods: they have a body
divided into three regions (head, thorax, and abdomen), have three pairs of legs, and mouthparts located How to Make a Cladogram (Adapted from ENSI/SENSI lesson plan: Making Cladograms http://www.indiana.edu/~ensiweb/home.html) Cladograms are diagrams which depict the The Water Cycle for Schools and Students: Advanced students. The water cycle describes how Earth's water is not only always changing forms, between liquid (rain), solid (ice), and gas (vapor), but also moving on, above, and in the Earth. Groundwater What is groundwater? These kids probably think there is some kind of magic happening here they pull down a lever and out of the ground below their feet comes clear, cool freshwater. Pythium debaryanum kills seedlings of a number of plants through collapse of stem just above the ground level. 4. Downy Mildew: The pathogen
produces a cottony or wooly bloom on the surface of the host. Worm Reproduction & Development. Reproduction dictates survival of a species. Organisms like worms which provide food for many others, must reproduce ample
offspring to offset predation. Surgical Drains Explained. In most abdominoplasty procedures, the plastic surgeon will insert one or more surgical drains to help prevent a build up of fluid behind the abdominoplasty incision and in the area that was operated on.
