  • Name of Phyla-  Cnidaria 
  • Digestion - how it eats?- They are a carnivore and they eat small plankton organisms. They take in food with its tentacles, bringing food into its body for digestion.
  • Excretion - how it removes waste?- Waste is discharged through the mouth.
  • Circulation - does it have a heart?- Does not have a circulatory system.
  • Respiration - how does it breathe?- They do not have lungs or respiratory organs they use their body cells to take in oxygen.
  • Nervous System - how does it feel or sense?- A nerve net has condensed to form nerve plexuses or nerve tracks which may be syncytia.
  • Reproduction - how does it produce it's offspring? - They release sperm or eggs into the ocean which means they reproduce asexually.

  • Name of Phyla
    • Echinodermata- Sea star
    1. Digestion - how it eats?
    They have a mouth on the bottom of their tummy. Food can be brought into the stomach through the mouth or the cardiac stomach can be extended out through the mouth to digest things outside of the body. Some types of starfish use their tube feet to pass food to their mouth
    1. Excretion - how it removes waste?
    The sea star has no excretory organs. They have a water- vascular system. It has cells devoted to taking waste and passing it along tiny opening to the tube feet that excrete the waste as urine
    1. Circulation - does it have a heart?
    Sea stars have a unique circulatory system. They do not pump blood. They use their water- vascular system to keep things moving.They do not have a heart 
    1. Respiration - how does it breathe?
    They breathe through their feet. They have tube feet that are made of very thin tissue, so gases can move through them easily.
    1. Nervous System - how does it feel or sense? Sea stars have no heart. The nervous system is characterised by a nerve ring that surrounds the mouth. A radial nerve branches off of the nerve ring and extends to each arm.
    2. Reproduction - how does it produce it's offspring? 
    Sea stars can reproduce sexually and asexually. They hold their sperm and eggs in pouches at the base of their arms.

    Bryozoans
    Digestion - how it eats?
    They are filter feeders that eat small organisms such as phytoplankton.
    Excretion - how it removes waste?
    Waste is excreted through the anus
    Circulation - does it have a heart?
    No heart
    Respiration - how does it breathe?
    They have no respiratory organs so they absorb the oxygen and eliminate carbon dioxide through the body wall.
    Nervous System - how does it feel or sense?
    Their nervous system is located in the polypide so they are able to feel and sense.
    Reproduction - how does it produce it's offspring?
    They are both male and female. They all release sperm into the water and some release eggs into the water, but some catch the sperm and fertilise their eggs internally.

    1. Digestion - how it eats?
    It paralyzes it's prey and slowly consumes it.
    1. Excretion - how it removes waste?
    They use diffusion to remove waste from thie bodies.
    1. Circulation - does it have a heart?
    A jellyfish has no ears or eyes or nose and no brain or heart.
    1. Respiration - how does it breathe?
    jellyfish use cellular respiration from diffusion to breathe.
    1. Nervous System - how does it feel or sense?
    jellyfish have special cells along their tentacles called cnidocytes which act as sensory organs.
    1. Reproduction - how does it produce it's offspring? 
    jellyfish release sperm and eggs into the water, they reproduce asexualy.

    1. Name of Phyla Chordate turtle - 
    2. Digestion - how it eats? it eats plants small organisms and dead marine life so it doesn't have to hunt 
    3. Excretion - how it removes waste? they remove waste through their mouths as they can breathe through their butts 
    4. Circulation - does it have a heart? yes it has a 3 chamber heart 
      1. Respiration - how does it breathe? the have to come up to breathe oxygen but have adaptions that allow them to stay under water for long periods of time 
    5. Nervous System - how does it feel or sense? they have bumps under there chins that have ver god smell and sense in and out of the water
    6. Reproduction - how does it produce it's offspring?  they mate then lay there eggs on shore

  • Name of Phyla
    • Porifera (Sponges)
    1. Digestion - how it eats?
    They are filter feeders.
    1. Excretion - how it removes waste?
    Water passes through the sponge, flushing out all waste.
    1. Circulation - does it have a heart?
    The water flowing through it acts as a form of circulation.
    1. Respiration - how does it breathe?
    Again, The water flowing through it delivers the carbon dioxide and it absorbs sunlight. It photosynthesises.
    1. Nervous System - how does it feel or sense?
    They do not have a nervous system.
    1. Reproduction - how does it produce it's offspring? 
    They reproduce through budding. The break off a pce of their body and it grows into another body.

  • Name of Phyla Entoprocta
  • Digestion - how it eats? Entoprocta have a 'crown' of tentacles where the mouth and anus lies inside. the mouth opens and draws food inside to the mouth by the cilia on the tentacles. 
  • Excretion - how it removes waste? there stomachs are lined with microvilli which suck all the nutrients out of the food and then the waste is excreted into an ongoing current.  
  • Circulation - does it have a heart? the entoprocta has no heart or blood vessels.
  • Respiration - how does it breathe? no present
  • Nervous System - how does it feel or sense? it has one nervous system inside the crown (where the mouth and anus lie)
  • Reproduction - how does it produce it's offspring? it can switch between male and female but the egg must be feterlized in ovaries making it asexual

Most sponges are filter feeders, eating bacteria and other food particles in the water.Excretion - how it removes waste? A sponge has carbon dioxide and other wastes removed as the water moves in and out through the pores.Circulation - does it have a heart? They rely on keeping up a constant water flow through their bodies to obtain oxygenRespiration - how does it breathe? The ostia allow water, oxygen, and other nutrients to flow into the sponge's bodyNervous System - how does it feel or sense? They do not have a nervous systemReproduction - how does it produce it's offspring? Sponges reproduce by both asexual and sexual means. Most poriferans that reproduce by sexual means are hermaphroditic and produce eggs and sperm at different times. https://padlet.com/anna_vella1/rb75pmx5hyvk/wish/272418898 2018-08-08 23:45:58 UTC https://padlet.com/anna_vella1/rb75pmx5hyvk/wish/272418898 Assia https://padlet.com/anna_vella1/rb75pmx5hyvk/wish/272419849

    Chordate
    - Digestion - how it eats?
    Chordates eat through their mouths, breaking down food with their teeth and stomach acids, taking in the nutrients through the intestines.
    - Excretion - how it removes waste?
    Chordates excrete by disposing of waste through their bowels out the anus.
    - Circulation - does it have a heart?
    Yes
    - Respiration - how does it breathe?
    Water Chordates breathe through their gills, which they require to be wet to function, oxygen is taken in through the water into the body where it is then processed.
    - Nervous System - how does it feel or sense?
    Chordates feel through their PNS, censors are located throughout their body which allow them to feel, these censors are connected to the brain by nerves.
    - Reproduction - how does it produce it's offspring? 
    Chordates reproduce through sexual intercourse with other beings pertaining to the same species.
