Where do plants get their replacement electrons?
They are obtained from water. Photolysis of water release Electrons
WHAT IS THE RULE FOR REPLACEMENT REACTIONS?
Metals which have the ability to easily lost electrons replace the others.Halogens which have the ability to gain electrons replace the others.
Where does photo-system 2 get its replacement electrons from?
Photosystem II (PSII) obtains its replacement electrons from water molecules during the process of photolysis. When water is split into oxygen, protons, and electrons, the electrons released are used to replenish those lost by PSII after it absorbs light energy. This process also generates oxygen as a byproduct, which is released into the atmosphere.
What is the importance of emission of electrons from chlorophyll during photosynthesis in plants?
they are carrying energy. that is why itis important.
What heppens when light strikes green plant pigments?
electrons become excited

Will plants die if you don't give water?
Yes and for two reasons id the plant is vascular. One reason is that turgor pressure is not maintained without water and the plant can not hold itself erect then. The second and more important reason is that the plant needs to split water molecules to get replacement electrons when the chlorophyll pigment is excited by photon strike and it's electrons enter photosystem II. Without the replacement of those lost electrons there would be no photosynthesis and the plant would die in short order.
Is succcession the gradual replacement of one community of plants by another community?
yes
This is the mineralized remains of plants or animals?
It is called replacement .

What does a plant do with a water?
When the light cascade finally releases the P680 electrons to the primary electron acceptor of the reaction complex those electrons must be replaced. The plant has an enzyme that preforms photolysis on water, splitting it, so that two electrons are fed one at a time into the p680 chlorophylls as replacement electrons for those they have released to the primary electron acceptor.

What picks up energized electrons from reactions in the thylakoids of plants during photosynthesis?
The molecule that picks up energized electrons in the thylakoid membranes during photosynthesis is called NADP+ (nicotinamide adenine dinucleotide phosphate). It accepts the electrons and is reduced to NADPH, which then carries the electrons to the Calvin cycle for the production of sugars.
Where is energy in the glucose stored?
The energy in glucose is stored in the covalent bonds between the molecules, and most importantly, in the hydrogen electrons. The hydrogen electrons were boosted to a "higher energy level" in the process of photosynthesis (which is transfered by plants from sunlight) during the photosystem I in plants. These hyrogen electrons will than pass through the electron transport chain during aerobic cellular respiration, and the hydrogen ions become stable.
What do plants use during photosynthesis?
Photosynthesis is the process in which plants changes energy from the sun into chemical energy. That being said, photons from the sun are absorbed in the plants chloroplasts. These photons excite electrons that are present in the interior of the chloroplast. Electrons are located inside complexes known as photosystems, which are located in the membrane of thylakoids. Thylakoids are flattened sacs that are stacked together within the chloroplasts to form granum. When these electrons are excited they are passed on from Photosystem II to Photosystem I in a complex process that allows H+ ions to cross into the thylakoid. As the electrons are used up at each Photosystem they have to be replaced. This is where water comes in. Water gets "Split" apart and the electrons from water are donated to the Photosystem. So during photosynthesis plants use sunlight, water (to replace electrons), and NADP+ (this is an electron carrier that carries electrons to different cycles).
