Photosynthesis is a process in which a plant uses sunlight to create food, using CO2 and water.
Answer:
Complete digestion of food takes place in the intestine. Various enzymes present in the intestine act on food and digested food gets absorbed. Typhlosole increases the absorption surface of the intestine.13
Answer:
C. They have a continental rise.
Explanation:
Answer:
C. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too little ATP.
Explanation:
Plant withering refers to the virtual death of plant cells due to lack of food. During the light-dependent reactions of photosynthesis, ATP needed for the synthesis of sugar (food) is created in the thylakoid membrane of the CHLOROPLAST of plant cells.
In the light-dependent reaction, hydrogen ions (H+) builds up/accumulate in the thylakoid lumen to create an electrochemical or proton gradient i.e. a difference in the concentration of H+ ions across the membrane. The hydrogen ions passes through a protein complex called ATP synthase, which forms ATP from ADP (by adding phosphate group), from the energy generated by the electrochemical gradient formed as a result of hydrogen in (H+) build up.
Hence, a plant that possess leaky membrane due to the cold temperature will likely wither because H+ ions are not able to accumulate inside the thylakoid causing a proton gradient, so ATP synthase makes too little ATP.
