- tissues
- Sponges have no enbryotic germ layers, so no what?
- vertebrate
- animals with backbones
- No
- Do sponges have a nervous system (many sponges produce toxins)
- water
- waste diffuses into what?
- what can you infer about an animal based on symmetry?
- there charcteritics of that animal
- flatworms
- are flat ad as foft as jelly-many are parsites- Ex planarians, flkes and tapeworms
- why are coral reefs important?
- they provide a home for many underwater creatures
- Both
- Do sponges reproduce sexually or asexually?
- what are the different of symmetry and examples of each?
- radial-starfish bilateral-fish no symmertry- sponge
- 4
- What step? - Archaeocytes carry the sperm to an egg located in the wall of the sponge
- invertebrate
- animals without backbones-make up most of the animal species on Earth
- closed circulatory system
- the blood flows only through connected tubes called blood vessels. A closed circulatory system moves blood around an animals body faster than an open circulatory system.
- coral reef
- is a mound of skeletons from cnidarian colony that the polyp produces a hard skeleton around its soft body and when the animal die the hard skeleton remains-forming the coral reef. *Coral reefs are home to more species of fishes and invertebrates than any other environment on Earth.
- fertilization
- the joining of an egg cell and a sperm cell
- archaeocytes
- what is the sperm transfered to by sexual reproduction
- what is symmetry?
- symmetry is the balanced arrangment of a animals body.
- What are the three major phyl for worms?
- flatworms, roundworms, and segmented worms.
- Monoecious
- Reproduction - can produce both egg and sperm; do not self fertilize (most sponges)
- Phylum Porifera
- Sponges (pore-filled)
- dioecious
- Few are this, have separate sexes
- 7
- What step? - Larva swims away and eventually attaches to a surface go become a new sponge
- polyp
- a cnidarian shaped something lide a vase with the mouth opening at the top. Example sea anemone
- What are the different types of symmeter and an example of an animal rom each?
- Bilateral-has a line of symmetry that divides it into halves that are mirror images. Example-fish Radial have many lines of symmetry that all go through a central point. Ex-starfish Some animals have no symmetry. Ex-sponge
- 2
- What step? - COllar cells engulf sperm
- gemmules
- type of asexual reproduction - freshwater sponges use these alot - food filled balls of archaeocytes surrounded by a protective coat and spiccules - Can survive harsh conditions and later develop into a new sponge
- Why are coral reefs important?
- Coral reefs are home to more spedcies of fishes and invertebrates than any other enviroment on Earth.
- anus
- an opening at the end of the tube where waste leave the digestive system
- Characteristic - Habitat
- Aquatic: Some fresh water; most marine
- collar cells
- what engulfs the sperm in sexual reproduction
- respiration
- diffusion - constant stream of o2 - brings o2 in and carries co2 away
- archaeocytes
- what are nutrients picked up by during the digestion of food in sponges
- food
- bacteria, unicellular algae, protozoans
- bilateral symmetry
- an animal that has a line of symmetry that divides it into halves that are mirror images.
- parasite
- an organism that lives inside or on another organism
- regenneration
- type of asexual reproduction - Sponges can regrow missing parts OR a small part can grow into a new sponge
- colony
- a goup of man individual animals-some cnidarian live in a colony Examples stony corals and Portuguese man-of-war
- 1
- What step? - Sperm is released from sponge and introduced into the incurrent pore of the second sponge
- Hemaphrodites
- Most sponges have male and female reproductive structures
- 6
- What step? - Zygote develops in the wall of the sponge and becomes a larva
- Spicules
- What do sponges use for support?
- sessile
- adults are what (attached)?
- filter food from water
- when a current is created what are the collar cells then able to do?
- medusa
- a cnidarian is shaped like a bowl with a mouth that opens downward Example jellyfish
- larva
- an immature form of an animal that looks very different from the adult
- What can you infer about an animal based on its symmetry?
- Can tell where they like-radial live in water-slow moving or dont move at all. Bilateral are larger animals with more complex and streamlined bodies which allow these animal to move more quickly.
- 3
- What step? - Sperm transfered to archaeocytes
- diffusion
- constant stream of oxygen
- excreation
- (N - wastes) diffusion (ammonia)
- wall of sponge
- Where does that zygote develop?
- phylum
- the 35 major groups of animals that biologists have defined
- role of chanocytes
- engulf and digest the food; nutrients are released and are picked up by the archaeocytes
- larva
- immature stage of life cycle
- what are 4 major functions of animals?
- four major functions are to obtain food and oxygen, movement,maintitaing internal stable condition,and reproduction
- cellular
- what is the sponges level of organization?
- egg
- achaeocytes carry the sperm where?
- what characteristics do scientist use to classfiy animals?
- they use DNA to classfiey animals.
- archaeocytes
- cells that crawl through the sponge and have the ability to change into the other three types of cells (epidermal, collar cells, porocytes)
- yes
- Are the asymmetrical?
- what are the main charcteritics of a cnidarians?
- they have radial symmetry and hacve stinging cells
- collar cells
- what do filter feeders use to move water into the sponges through pores and out through the osculum?
- wall of sponge
- where is the egg that the sperm is carried to located?
- chanocytes
- collar cells
- what are the main charcteristics of worms?
- the main charcteristics of worms is they have a closed circulatory system, some are scanvgers while others are free-living, and thye have 2 body openings
- asexual reproduction
- when an organism produces an identical copy of itself
- what are the 3 main phyla of worms
- the 3 main phyla are flatworms, roundworms, and segmented worms
- tissue
- a group of similar cells that perform a specific function
- how are animals bodies typically organized?
- they are organized from cells, to tissue, to organ, and than system.
- adaptation
- structures or behaviors that allow animals to perform gthese basic functions (obtain foodand oxygen, keep internal conditions stable, move, and reproduce)in their environments.
- What is the simplest animal to have a brain?
- worms
- free-living organism
- organismy that do not live in or on other orgainsms-Ex planarians
- what are the main chacteritics of animals?
- the main charcteritics of a sponge is they dont move and they are filter feeders and they have no symmetry
- 5
- What step? - Fertilization occurs and zygote is formed
- host
- the organismy in or on which parasites live- where parisites takes its food from
- What are the main characterisitxs of anidarians?
- Are invertebrates that have stinging cells and take food into a central body cavity. They use stinging cells to capture food and defend themselves.
- sponges and cnidarians
- live in water are invertebrate animals that usually have no body symmetry and never have tissues or organs
- What characteristics do scientist us to classify and animal?
- Animals are classified according to how they related to other animals. These relationships are determined y the animals body sturcture, the way the animal develops and its DNA.
- organ
- a group of different tissues that performs a more complex function than each tissue could perform alone
- No
- Do sponges have a skeleton (internal or external)?
- budding
- type of asexual reproduction - develop small "buds" (cells) that break off and live separately
- sexual reproduction
- the process by which a new organism develops from the joining of two sex cells
- scavengers
- feed on dead or decaying material. Ex planarians
- cell
- the basic unit of structure and function in living things
- What are the main characteristics of sponges?
- They are invertebrate animals that usually have no body symmetry and never have tissues or organs. They stay in one place. They reproduce both asexually and sexually.
- 1st animals sponges
- What marks the transition from unicellular to multicellular life?
- how are animals classified?
- the are classfied in groups called phylums
- radial symmetry
- animals with many lines of smmetry that all go through a central point
- cnidarian
- invertebrates that have stinging cells and take food into a central body cavity- Example-jellyfish, sea anemones and corals- They use stinging cells to capture food and defend themselves
- Using flagella
- how do collar cells create a current?
