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
Evolutionary adaptations that help diverse animals exchange matter with the environment include?
External respiratory surface, small size and two-layered body
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.
How does exchange of gases takes place in unicellular organisms?
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:a large surface areaa thin permeable surfacea moist exchange surface.Read more: How_does_gas_exchange_take_place
Why the epithelium is much better suited for the body's external surface than mucosa?
Mucus epithelium is very delicate. It can not protect your body from the rough external environment. You need the tough stratified squamous epithelium to protect you from the rough external environment.
How do partial pressures of gases influence the exchange of gas?
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism.

Is gas exchange the same thing a respiration?
inhalation and exhalation takes place in respiration.Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism.therefore they both are same things.
Define external respiration?
External Respiration-the process of first inhaling oxygen (02) and then proceeding to EXHALING the inhaled oxygen in the lungs in the form of carbon dioxide (C02) into the environment, then repeating the process all over again. (the entire process is commonly known as cellular respiration.)

Which organism has a gas exchange surface adapted for a terrestrial environment?
earthworms.

What is free surface?
An epithelium always has on surface where the cells are exposed either to the external environment or to an internal passageway or cavity; this surface is called the free surface of the epithelium.
