Electron transport chain is found in both cellular respiration and in the light reactions of photosynthesis.
<h3>What is Electron transport chain ?</h3>
- An electron transport chain is a collection of protein complexes and other molecules that couple protons across a membrane with the transfer of electrons
- from electron donors to electron acceptors via redox reactions. a group of proteins in the mitochondria's inner membrane.
- The oxidative phosphorylation process, also known as the electron transport chain.
- Is a collection of four protein complexes that combine redox events to produce an electrochemical gradient that results in the production of ATP.
- Both photosynthesis and cellular respiration take place in mitochondria.

Root hairs have hair like extensions which help increase the surface for absorption of water and mineral salts from the soil. It is similar in function to the villi of the intestinal tract which also has hair like extensions to increase the surface area for absorption of nutrients.
Answer:
The correct answer is option A. "The contents of blood come into closer contact with tissues in a closed system than an open system".
Explanation:
In a closed circulatory system, the blood has an specific path, circulating from arteries to veins and to smaller blood vessels throughout the body. This is in contrast with open circulatory systems at which the blood is not contained in arteries or veins but it suffuses the body. A closed circulatory system have many advantages over open circulatory system, however in a closed circulatory system the contents of blood are not into closer contact with tissues in than an open system. Actually, in an open circulatory system the blood is in closer contact with tissues.
False because cells don’t have different cells function
