Obtaining and using energy
Autotrophs use energy to grow, go through photosynthesis, and to produce more cells.
Heterotrophs use energy to eat, sleep, and do any sort of physical activity.
An autotroph is an organism that makes its own food
A heterotroph is an organism that obtains energy from the food it consumes
A heterotroph is an organism that obtains energy from the food it consumes

Autotrophs use energy to grow, go through photosynthesis, and produce more cells.
Heterotrophs use energy to eat, sleep, and to preform any physical activity.
ATP and ADP are like a phone battery in the sense of energy. ATP contains large amounts of energy, like a fully charged battery. ADP contains small amounts of energy like a battery loosing charge. ATP can turn into ADP when it looses energy, like when a fully charged battery drops 50 percent.
ATP is the preferred energy source because it has more energy. It's like charging your phone, you would rather have a fully charged battery than a half charged one so it can work to its full potiential
How do cells get energy?
Animal cells get energy by going through cellular respiration and plant cells get energy by going through photosynthesis.
Photosynthesis
Photosynthesis is a chemical reaction that requires the energy of sunlight to convert water and carbon dioxide into glucose and oxygen.
Photosynthesis begins with the thylakoids beginning a light reaction by taking in water and light energy. From that it produces oxygen, which it then releases, ATP, and NADPH. Next the Calvin Cycle takes place in the stroma and it uses that ATP and NADPH to produce and release sugars. It also produces NADP+ and ADP which the thylakoids then use to start the process over again
Cellular Respiration
Cellular respiration is a chemical reaction that releases energy by breaking down glucose in the presence of oxygen.
Cellular resliration takes place in the mitochondrion to produce energy for plants . First glucose is broken down into glycolysis which gives off a little energy the distributes the rest into a part in the mitochondrion. That glycolysis, in addition to oxygen go through the Kreb's Cycle to release some energy then pass on some other products to other parts of the mitochondrion. The last of the reactants go through electron transport which releases the majority of the energy and also water and carbon dioxide.
