Living cells require energy for the activities of life. Energy is released in every cell by the process of Cellular Respiration. In this process glucose is oxidised to produce energy. Gases need to be exchanged between the cells undergoing Cellular Respiration and the environment. In most organisms these gases are oxygen and carbon dioxide.

 

You are to compare the structures and processes involved in gas exchange in an Angiosperm, Insect, Fish, Amphibian and a mammal.

 

- The purpose of gas exchange in these organisms

 

- The structures involved for exchanging gases in each of the above organisms.

 

- How gases are exchanged between the organisms and its environment.

- Why the organisms has these special structures/processes (relate to the different environments).

Please If you can answer any just do it and you will help me alot ...

 

 

Thanks indeed,

cmon guys any one can help ?

Fish

This is all i have time for now...i'll try and find some more after i come back from college. Try to find out about each individual creature, then compare; mammals and fish should be easy enough.

We aren't doing your homework for you.

I wish I would have known about this site when I was a high school student...

right thanks for that ...

 

btw Sayonara, that was so nice ...

Really? It wasn't supposed to be.

 

If you are going to copy your homework assignments here verbatim then the least you could do is put it in the right forum.

 

- The purpose of gas exchange in these organisms

 

 

asking this type of relatively easy question shows that you can't be bothered to do a little bit of research. try searching at http://www.imtoolazy2doanything.com

 

sorry to seem a little harsh.......

 

 

 

 

 

 

 

 

 

 

....but u really do deseve it for these questions

woah guys, lool chill down, my assignment is due 2 weeks from now so i thought to post the Assign. question in here so that maybe I would recieve couple answers untill I start working and researching it...

LoL im not lazy but I still didnt start,,,

A couple of quick answers to help get you started.

Provide oxygen to cells for respiration obviously, plus in autotrophs carbon dioxide is required for photosynthesising cells.
