What is the function of the cell membrane and the plasma membrane?
Cell membrane is also known as plasma membrane. Controls exchange of materials such as nutrients and waste between cells and their environment. Has other important functions for example to enable cells to receive hormones.
Where does the materials needed by cells come from?
They cross the cell membrane from the environment.
What is the effects of the exchange of oxygen and carbon dioxide between internal leaf cells and the external environment?
the surface of these cells are moist and the stomatas are open
What are the three phases of transferring gases between the environment and the cells?
The three phases of transferring gases between the environment and the cells: Breathing, the transport of gases and the exchange of gases. (Came straight from my biology textbook)
Why multicellular organisms need special organs for exchange of gases between their body and their environment?
Our body is made up of prokaryotic cells. These cells are not in the contact with the environment. So the process of diffussion cant make any difference in exchange of gasses between the multicellular boy and environment.
What is the main reason cells exchange materials with the environment around.?
to get rid of wastes and take in nutrients
Which materials are exchange between the blood and the body cells?
capillaries
Why can smaller cells exchange materials faster than larger cells?
Because the materials can go through the small cell faster

Where does the materials needed by cells come from?
They cross the cell membrane from the environment.
What vessels exchange materials with the extra cellular fluid and the blood?
Capillaries. Since they are only once endothelial cell thick, they can exchange gas, nutrients, and waste across their membrane. Capillaries in the brain have endothelial cells close together to onyl allow a slecetive exchange of materials, while capillaries in the kidney or liver have gaps between the endothelial cells to allow the exchange of a lot of materials.

Controls exchange of materials such as nutrients and waste between cells and their environment. Has other important functions for example to enable cells to receive hormones.
What most important thing happens in the capillaries?
materials exchange between blood cells and blood

What are the small vessels where blood exchanges various materials with cells?
The human circulatory system consists of arteries, veins, and capillaries. The capillaries are the thin-walled vessels that connect arteries and veins and allow for the exchange of materials between blood and tissue fluid.
