How do paramecium and frogs transport oxygen from their enviroments into their cells?

Question

Paramecium may be replaced with any unicellular organism and the frog may be replaced with any multicellular organism. Also why is the frog's oxygen transport system more complex?

Answer 1

Paramecium are one cells "animals" that live in water. Oxygen is obtained from the water by a process called diffusion...it simply crosses the cell membrane because there is more oxygen in the water than there is in the Paramecium.
The frog is a multicelled animal however it obtains oxygen in 2 ways. Firstly it breaths in oxygen, as we do, through its nose. Its lungs act as ours do and are the site where oxygen enters the blood and is circulated through the body by the heart and blood vessel. However the frog also has tiny capillaries throughout its skin. The skin is moist and this facilitates oxygen from the environment to diffuse into these capillaries. This oxygen is also circulated throughout its body by the heart. This is why the frog can hibernate in the winter by digging itself into the bottom of a water body...it "breathes" through its skin all winter. Also, in the summer if you want to catch a frog make sure you wet your hands before you touch the frog. Your dry hands can remove the moisture from the frog skin, which it needs to "skin breathe".

Answer 2

An ideal respiratory membrane has four basic requirements:
1. thin 2. moist, 3. close to a supply of oxygen 4. close to a blood or transport system.
Unicellular organisms: The cell membrane has all of the above requirements; external surface.
Multicellular organisms : In some large multicellular organisms, oxygen diffuses into the cells internally. In humans, for example ,oxygen must make its way into the lungs. Once there, oxygen enters into cells via the alviolus, which is the respiratory membrane.
In some large organisms, the respiratory membrane is the outside (external) skin, like the earthworm. A frog has two places of oxygen entry; lungs & skin.

Answer 3

No. A frog is a frog. you won't be in a position to make one right into a prince no be counted how lots you attempt. A frog could prefer to alter right into a prince on his own, yet once you have ever customary him as a frog, he has no motivation to be the rest for you. by employing determining on frogs you in basic terms inspire frogs to stay frogs. per probability you're able to be greater valuable off searching for somebody who substitute into already a prince as a replace.
