	Extrusome
		Extrusomes are membrane-bound structures in some eukaryotes which, under certain conditions, discharge their contents outside the cell.
		Notable extrusomes include mucocysts, which discharge a mucous mass sometimes used in cyst formation, and trichocysts, which discharge a fibrous rod.
		The stinging nematocysts found in Cnidarian animals may be regarded as extrusomes as well.

	Ciliate (Site not responding. Last check: 2007-10-31)
		Another are the alveoli, small vesicles under the cell membrane that are packed against it to form a pellicle maintaining the cell's shape, which varies from flexible and contractile to rigid.
		Numerous mitochondria and extrusome s are also generally present.
		The presence of alveoli, the structure of the cilia, the form of mitosis and various other details indicate a close relationship between the ciliates, Apicomplexa, and dinoflagellate s.

	Peniculid - Wikipedia, the free encyclopedia
		Typically the body has uniform, dense cilia, which also cover a vestibule preceding the mouth.
		Extrusomes are characteristically in the form of spindle trichocysts, which release thread-like shafts, and never mucocysts.
		The oral cilia include peniculi, corresponding to the membranelles of related groups, arranged parallel to the mouth deep in the oral cavity.

		Extrusomes may be used for protection or prey capture.
		As extrusomes, sagittocysts are comparable to nematocysts, colloblasts, rhabdites, and other extrusomes common especially to lower eumetazoans, and the origin of all such extrusomes may correlate with the origin of the eumetazoan gut.
		[Somatic Cortex: extrusomes] The extrusomes are distributed between kinetids of the kinety as in Lechriopyla.

	biology of trees
		They may be supported internally (actinopods) or not (rhizopoda), they may be thread like (filose) or broad (lobose), may or may not bear extrusomes (nudipodia, extrusopodia) and they may be one (monopodial) to many (polypodial) produced at one time.
		May be thought of as an adaptation in response to a lack of food and the task of which is to hunt out new sources of food.
		A type of extrusome which, when extruded, takes the form of a fine stiff filament.

		Axopodia, unlile the scales, radiate from the cell body at right angles to the cell surface.
		They are longer and much more slender than the scales and may bear prominent beads ("kinetocysts", a structurally distinct type of extrusome).
		Axopodia are used to capture prey and to move cells along a substrate.

	eukaryote
		For instance, lysosomes contain enzymes that break down the contents of food vacuoles, and peroxisomes are used to break down peroxide which is toxic otherwise.
		Many protozoa have contractile vacuoles, which collect and expel excess water, and extrusomes, which expel material used to deflect predators or capture prey.
		In multicellular organisms, hormones are often produced in vesicles.

		These come in various shapes and arrangements, depending on the species and sometimes stage of the dinoflagellate.
		Fibrous extrusomes are also found in many forms.
		Together with various other structural and genetic details, this organization indicates a close relationship between the dinoflagellates, Apicomplexa, and ciliates, collectively referred to as the alveolates.

	Nassophorea - Wikipedia, the free encyclopedia
		The mouth is anterior ventral and leads to a curved cytopharynx supported by a prominent palisade of rods or nematodesmata, forming a structure called a cyrtos or nasse, typical of this and a few other classes.
		When present, extrusomes take the form of fibrous trichocysts.
		Cilia are usually monokinetids, but vary from order to order.

		Intermediate character states in different species will enable us to reconstruct the transformation series associated with the evolution of these complex organelles.
		The combination of photoreception apparatus, feeding apparatus, and extrusome type will be analysed to compare and contrast feeding behaviours in different species.
		The diversity will be placed in the molecular phylogenetic context established from the DNA sequencing research.
