Question

Hi do you know what mitochondria is (im obviously horrible at this kinda stuff)

Answer 1

Its okay, its better to ask than not know. The mitochondria is an organelle in which respiration takes place, they generate energy for the cell by producing ATP.

Also mitochondria are involved in a range of other processes, such as signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth (but the main part is the energy generation).

Answer 2

There are some good descriptions of other cell parts here: http://library.thinkquest.org/12413/structures.html

and here: http://biology.clc.uc.edu/courses/bio104/cells.htm

Answer 3

thanks!

Answer 4

Not a problem :)

Answer 5

what is a rough and smooth ER

Answer 6

The "rough" appearance of the rough endoplasmic reticulum (RER) results from the presence of ribosomes that are bound to the cytosolic side of the endoplasmic reticulum membrane. The presence of ribosomes on the RER indicates that it is involved in protein synthesis.

The smooth endoplasmic reticulum (SER) has no such bound ribosomes and is not involved in protein synthesis. However, the SER is involved in cholesterol metabolism, membrane synthesis, detoxification, and other cell processes.

Answer 7

Thats a bit to advanced for my understanding can you just tell me their main functions (once again sorry for lack of biology skills)

Answer 8

rough= protein building
smooth= lipid building

Answer 9

@ Hcgturtle, yep the rough makes proteins, the smooth does make lipids but it also makes a bunch of other stuff (like helps in metabolism)

Answer 10

cool, thanks, are you a teacher because im in 7th grade and your better than mine

Answer 11

Haha, no I'm not a teacher, and I doubt I'm better than yours, I don't think I would have a hope in teaching a whole class

Answer 12

yep

Answer 13

at the one about smooth er

Answer 14

how do you know all of this then?

Answer 15

Haha, well I learnt it. Though awhile ago, mostly I just grab the answer off the internet

Answer 16

you have some really good sources then

Answer 17

Well they're not all that hard to find, I suppose it needs a little understanding but Wikipedia is great.

Answer 18

But cant anyone post random junk to wikipedia?

Answer 19

sorry you probably need to help people with questions! (:

Answer 20

the best resource is the lecture book. even though they cost 200bucks for a new one. :(

Answer 21

its okay, well its true that people can post random junk on wikipedia but alot of people get really annoyed when the wrong thing is posted on wiki so they change it be correct, the end result is that wikipedia is pretty accurate. The best way to tell if it is accurate or not is to check the articles references, if they reference journal articles and things then chances are the article is pretty accurate.

You're quite right Hcgturtle, the best reference is your books! Especially if your teacher has told you a specific one, that way it is at your year level.

Answer 22

Im gonna tell my teachers that and hope they let me use it for assignments

Answer 23

Hmm probably better not to, its a good starting point for assignments but its always better to double check it and don't use it as a primary reference.

Answer 24

thought so ( :

Answer 25

Yeah, its a bummer but atleast its great for background and reading if you can't work something out.

Answer 26

whats a chloroplast?

Answer 27

Hehe, are you doing your homework?

It only occurs in plant cells and is where light energy is converted into chemical energy. So uses the sun to get energy that it can use.

Answer 28

yes i am doing my homework (:

Answer 29

I hope I'm not giving you all of the answers lol

Answer 30

not really well sort of i just ask you for the basic answer then do research on that more in depth.

Answer 31

Great! Good work! I hate it when people just ask for answers and just write it down for their homework, happy you do more research :)

Answer 32

Thanks when you go to an advanced studies school their EXTREMELY strict about cheating and what not.

Answer 33

Mmm, that they are

Answer 34

Thanks for the medal!
PS:
do you like my picture for my profile!

Answer 35

No worries, thought you deserved it for doing more research :)

Yeah, who doesn't like pirates of the Carribean! :P

Answer 36

haha! i love it!!!

Answer 37

Are you here everyday? Your a big help.
