Need some help with some science homework.
I have to read these two paragraphs then sumerize them in three sentences. I'm not lazy, I just don't get it.
Large protein molecules and bacteria may enter a cell when they are surrounded by the cell membrane. The cell membrane folds in on itself, enclosing the item in a sphere. The sphere pinches off, and the resulting vacuole enters the cytoplasm. This process is called [b] endocytosis [/b] (en duh sy TOH sus). Some one-celled organisms, such as amoebas, take in food this way.
Vesicles and vacuoles are transport and storage structures in a cell's cytoplasm. They release their contents outside the cell by a process called [b] exocytosis [/b] (ek soh sy TOH sus). Exocytosis happens in the opposite way that endocytosis happens. The membrane of the vesicle or vacuole fuses with the cell's membrane, and the vesicle's or vacuol's contents are released.

I will let you flamme away ,but if it isnt shut up .

science sucks ass i like social studies i always ace it.

I don't know, but when you get into college and stuff the suffix "sis" is in atleast evey word. So get used to hearing it and knowing what it means. (It's sorta like pfhor on Marathon)

Not serious here....

The baggie is the cell membrane and the dog crap is the large protein molecules and bacteria. You encircle the crap and take it in and close the baggie. Exocytosis is just the opposite. I know this isin't a superb analogy, but I hope it helps.

That came straight out of our text books that says 8th grade on it.

Your taking bio in the 8th grade?

Hey can any one help me with physics? I'm totally lost. [Edited on 3/30/2005 7:15:13 PM]

Ok, science taught by a grade school student, here goes. Large protein molecules and bacteria enter a cell by means of the cell folding in on itself, Imagine a deflated ball wrapping around an apple. Vacuoles and Vesicles are places where the cell stores stuff. Ecocytosis is when the outer skin of the vesicle and vacuole fuse together, and as a result, the contents are released. Also, Endocytosis happens when the cells split apart, as far as I can tell from the information given. I know too much for a 13-year-old

what grade are you in? i learned that in 7th. edit: ^ i did not see that. [Edited on 3/30/2005 6:38:58 PM]

How old are you? I did that stuff in 7th grade.

Bio sucks, it's all about Chemistry and Physics.
-
Good. I, personally, would have the word "poop" in there someplace, but to each his own.
-
How about this. One-celled organisms eat by taking stuff like large proteins and bacteria into their cell membrane. Endocytosis and exocytosis are two ways for transporting materials into a cytoplasm. Endocytosis pinches off and it enters the cytoplasm, and exocytosis attaches and the contents are released.

Thanks Obbi and folks. I'm not all that great at science but I had my scedual changed for two other classes so I had to take advance science. [Edited on 3/30/2005 6:09:40 PM]

[quote][b]Posted by:[/b] fastmatt Endo and exo cytosis are two ways for transporting materials into a cytoplasm. One pinches off, and it enters the cytoplasm. The other attaches, and the contents are released.[/quote] I think if you add the cell membrane in there somewhere, you have a winning three sentences.

Like I am really going to help you dumb-ass! After that disgusting and vulgar PM you sent me. [Edited on 3/30/2005 6:09:20 PM]

When the cell needs to poop (so to speak) they connect with the cell membrane and all the unwanted stuff is released.
