Antonym of the word "sessile", or non-moving.
|
|
|
The characteristics that describe an animals amount of cells and method of obtaining food.
|
multicellular heterotrophs
|
Either unicellular or multicellular (regarding the amount of cells) and autotrophic (meaning we make our own food) or heterotropic (meaning we digest other organisms for food)
|
|
|
The term describing an animal that exhibits no symmetry.
|
asymmetrical/asymmetry
|
Try putting the prefix meaning "not" in front of "symmetrical."
|
|
|
The term describing an animal that has many lines of symmetry that all intersect in the center of the organism.
|
radially symmetrical/ radial symmetry
|
The first word shares the same root with the mathematical term meaning "half the diameter."
|
|
|
The term describing an animal that has only one line of symmetry, which runs down the middle of the organism.
|
bilaterally symmetrical/ bilateral symmetry
|
Use the prefix meaning "two." Now what is "two" referring to (think about a line running down the middle of something)? Use that to determine the root.
|
|
|
Give an example of asymmetry.
|
sponge
|
Something your mother probably uses everyday in the kitchen.
|
|
|
Give an example of radial symmetry.
|
jellyfish
|
An organism with the shape of a circle on its anterior side.
|
|
|
Give an example of bilateral symmetry.
|
human
|
Don't think too hard. If you can't get it, take a break and go look in a mirror. Maybe it will come to you.
|
|
|
This side on an animal that is the side with the head.
|
anterior side
|
Sounds a lot like the long things on the head of a moose.
|

The end of the animal with the anus.
|
posterior side
|
Think of the prefix for "before."

Many sharks and fish have these type of fins on their backs.
|
|
|
The underside or the belly of an animal.
|
ventral side

open to suggestions for hints
|
|
|
The formation of sex cells, also known as meiosis.
|
gametogenesis
|
Sex cells are called "gametes."
|
|
|
This is where the formation of sex cells takes place.
|
gonads
|
This is in general, not specific to any one gender.
|
|
|
The female's gonads.
|
ovaries
|
Here is where the ovum, or egg cells, are produced.
|
|
|
The specific name for producing ova.
|
oogenesis
|
The first syllable is repeated once.
|
|
|
In oogenesis, four haploid cells are produced, but only one goes on to become the egg. What happens to the other three?
|
They become polar bodies.
|
Something to do with Alaska or one the side on the outside of the cell membrane.
|
|
|
The male's gonads.
|
testes
|
|
|
|
This phylum consists of animals that are barely considered so. Many consider it to be in the Kingdom Plantae, but it cannot be a plant due to its inability to preform photosynthesis.
|
Phylum Porifera
|
A single organism in this phylum is sessile, but its larvae are motile (remember larvae does not only refer to bugs).
|
|
|
This phylum contains an organism that consumes small organisms and organic molecules using collar cells.
|
Phylum Porifera
|
|
|
|
These type of cells are found in the Phylum Porifera and help the organism eat by using their flagella to pull water towards them. The small other organisms in the flagella get caught in the mucus surrounding this cell and then they are consumed, with the water going back out of the top of the organism.
|
collar cells
|
Sponges have them.
|
|
|
This phylum has organisms that are neither protostomic or deuterostomic and are also acoelomates. They are also hermaphrodites and are made of spongin, a type of protein filaments, and spicules that are hard and sharp which makes them ideal for protection.
|
Phylum Porifera
|
These organisms can reproduce asexually and also can regenerate.
