Help paragraph writing and possibly an essay

[DrBlueThumb]

Was wondering If I could use this as a four point thesis statement?

Sponges are made of of four independent cells.

and

I was wondering if this is fine as a paragraph:

Collar cells line the interior canal wall of the sponge. Attached to the collar cells are little hair like appendages that whip back and forth, this whipping action helps pump water through the sponge, which results in supplying the sponge with nutrient and oxygen while removing waste and carbon dioxide from it's environment.

thanks Clint

Collar cells line the interior canal walls of the sponge. Attached to the collar cells are little hair-like appendages that whip back and forth; this whipping action helps pump water through the sponge, which results in the supply[STRIKE]ing [/STRIKE] of nutrient and oxygen to the sponge [STRIKE]with nutrient and oxygen[/STRIKE] while[STRIKE] removing[/STRIKE] waste and carbon dioxide from [STRIKE]it's[/STRIKE] its environment are removed.

 

[Raymott]

What do you mean by "Sponges are made of four independent cells." Most sponges I've seen have a lot more than four cells - in fact, a four-cell sponge would be almost invisible. Do you mean "four types of independent cell? In what way are they independent if they have to join together to make a sponge work?
Your thesis statement would work if all these questions are answered.

 

[DrBlueThumb]

Yes, thanks, "Sponges are made of four independent cells".

Collar cells line the interior canal walls of the sponge. Attached to the collar cells are little hair-like appendages that whip back and forth; this whipping action helps pump water through the sponge, which results in the supplying of nutrient and oxygen to the sponge while waste and carbon dioxide from it's its environmentare removed.

Collar cells line the interior canal walls of the sponge. Attached to the collar cells are little hair-like appendages that whip back and forth; this whipping action helps pump water through the (can I put the word porifera here?), which results in the supply of nutrient and oxygen to the ( can I put the word animal here?) while (not sure how to use the symbol for here ?)waste and carbon dioxide from its environment are removed.

 

[DrBlueThumb]

Nutrient? or nutrients?

Thanks everyone for your help.:up:

 

[DrBlueThumb]

Hows this:

Sponges are scientifically named porifera (meaning pore-bearing), they are made up of four main types of cells.??

 

[DrBlueThumb]

Sorry there are several different types of cells in the sponge.

Hows this: The sponge, also known scientifically as porifera, is made up of four main cells.

 

[tedmc]

Sponges, scientifically named porifera, which means "pore-bearing", are made up of four main types of cells.

There should be more than one type of nutrient, so "nutrients".

 

[DrBlueThumb]

help with this please:

Because of the lifestyle that the sea sponge leads, it does not have, nor does it need, nerve cells or muscle cells. Also, sensory organs such as; eyes, ears, nose, touch, tongue are absent, Which are the traditionally recognized senses of most animals. The sea sponge also lacks a digestive track, circulatory system and nervous system or internal organs of any kind.

Neurons are specialized cells that communicate with one another. The signaling of one nerve cell to another, takes place in a structure called the synapse. The synapse is a tiny area or gap between nerve cells or neurons in which chemical signals
(neurotransmitters) diffuse. Each neuron has regions of its cell membrane that send chemical signals, while other neurons specialize in receiving them.

I am not sure if it is scientific to say that the sea sponge 'leads a lifestyle'.
How about: behaviour or life patterns?

 

[DrBlueThumb]

Thanks, tedmc.

I'm trying to speak with authority in these paragraphs.

Sponges have evolved 500 million years ago, and are in fact, the oldest known multi-cellular organism on the planet. The scientific name is “porifera", meaning “pore bearer".

Most sponges are found in salt water oceans, while some inhabit fresh water lakes. Their habitat ranges from the warm shallow water of the tropics to the fridged cold artic.

(added a few things) this is going to be most of my intro.

Sponges have evolved for over 600 million years, and are in fact, the oldest known multi-cellular organism on the planet. The scientific name is “porifera", meaning “pore bearer". Over 15,000 species of sponges are found in the saline water of the oceans, coral reefs, mangrove estuaries and seagrass ecosystems, while only 150 inhabit fresh water lakes. Their habitat ranges from the warm, shallow water of the tropics to the frigid, cold Artic.

These invertebrates vary in growth from a few millimeters, to over 2 meters in size. Sponges come in a wide array of colours, from bright; yellow, orange, pink, blue, purple, green, and red, while others are a dull grey, white, black or brown. Different species of sponges form different shapes, including; tree like, fans, barrels, cones, tubes, cups, blobs and crusts. Their texture can be rough, smooth or like spun glass.

 

[DrBlueThumb]

Most sponges are heterotrophic, aka omnivore, feeding on both plant and animal organic substances. They feed mostly on suspended drifting microscopic and dissolved organic particles such as; phytoplankton, zooplankton, bacteria and dinoflagellates. Some deep sea sponges are even carnivorous, preying on small crustaceans and fish. While some shallow water species have been found to be heterotrophic and autotrophic, (mixotroph or bitroph), hosting a mutually beneficial symbiotic relationship with a microscopic unicellular algae called zooxanthellae, while also feeding on microscopic organic substances.

(changed a few things up a bit)

Most sponges are heterotrophic, specifically omnivore, feeding on both plant and animal organic substances. They feed mostly on suspended drifting microscopic and dissolved organic particles such as: phytoplankton, zooplankton, bacteria and dinoflagellates. Some deep sea sponges are even carnivorous, preying on small crustaceans and fish. Shallow water species are known to be partially autotrophic, harnessing a percentage of their nutritional requirements from the sun. They do this by hosting a mutually beneficial symbiotic relationship with a microscopic unicellular algae called zooxanthelae, most commonly found in corals. Although, they have this unique ability, they still rely heavily on being heterothrophic. So technically, these specific sponges are known as being, (mixothrophic or bitrophic).

1. I prefer "establishing" to "hosting" for a symbiotic relationship. My understanding is that "hosting" is used in a relationship where one side benefits more than the other, as in a parasitic relationship.

2. Why not say "mixothropic or bitrophic beings"?

3. It is understood that suspended articles drift.
