Cells need to be small in order to make exchanging materials faster. This is because, as the size of the cell increases (if we were to increase the size), then the volume increases faster than the surface area. We want more surface area, so this isn't effective if we increase the size. The larger the size also means that it takes more energy for them to move, so there will need to be more cytoplasm, and that's too much effort to generate. Imagine being in math class when you use those cubes, the one huge cube assembles 100 small cubes, that one huge cube has less surface area than those 100 small cubes combined. That's why we need small cells. A larger surface area allows for more exchanges to occur and a larger volume allows for more materials to be brought in or released from the cell at a given time. (The rate of exchange would increase for larger surface areas and volumes of cells.)
The answer would be C.
I took the quiz and this is correct.
Acids: hydrogen ions; bases: hydroxide ions
Answer: (A) The isolated chloroplasts will make ATP
Explanation:
The Thylakoid will receive hydrogen from the acid which is pumped across the thylakoid membrane, and the electrochemical proton synthesis of ATP begins in the stroma. Once the chloroplast has been transferred to the dark, high-energy electrons are loaded together with (H+) onto NADP+, converting it to NADPH.
Kingdom Plantae (all land plants). they are autotrophs which means they produce their own food through photosynthesis.
