Archaeocyte
Archaeocytes (from Greek archaios "beginning" and kytos "hollow vessel") or amoebocytes are amoeboid cells found in sponges. They are totipotent and have varied functions depending on the species.
Location
Archaeocytes are along with other specialized sponge cells including collencytes and structural elements called spicules. They move about within the mesohyl with amoeba-like movements performing a number of important functions.
Functions
Cellular differentiation is an essential function of the archaeocyte. All specialized cells within the sponge have its origins with the archaeocyte. This is especially important in reproduction as the sex cells of the sponge in sexual reproduction are formed from these amoeboid cells. Similarly in asexual reproduction amoebocytes result in the formation of gemmules which are cyst-like spheres containing more amoebocytes as well as other sponge cells including the phylum specific choanocyte. These cells move within the walls of a sponge and form spicules.

Are You A Ghost
by: B-witchedIts two in the mornin
I'll tell you why I'm awake.
There it goes, that creepy feeling again,
Round in my head.
Ohhh again, here in my head.
Here in the darkness
There's so many shapes.
Shadows burn like faded flames,
And die into the night.
Ohhhh and fly up so high.
Are you a ghost, or are you alive?
Would you be here for me,
Be here for me now?
Imagination, or are you for real?
Just give me a sign... and I'll know.
Cool wind is blowin.
Fingers through hair.
Standing in an empty room,
Alone it feels like you're there.
Oh, alone I know that you're there.
Are you a ghost, or are you alive?
Would you be here for me,
Be here for me now?
Imagination, or are you for real?
Just give me a sign.
I'll tell you what I know,
I'll tell you how I feel.
Are you a ghost, or are you alive?
Would you be here for me,
Be here for me now?
Imagination, or are you for real?
Just give me a sign... and I'll know.
Are you a ghost, or are you alive?
Whould you be here for me,
Be here for me now?
Imagination, or are you for real?
