Photosynthesis is done only by plants by using sunlight water and CO2

All living organisms can do cellular repirations

She is wrong because she said plants only do photosynthesis but that's not true because trees do cellular repiration too because when there is no sunlight they need energy. So what they do is they break down the sugar doing glycolysis by using mitochondria. Sidenote:Both plants and animals have mitochondria in their cells.They need energy right when there is no sun.So they use glycolysis.Glyco means sugar and lysis means break down.Then there come 2 steps.

Aerobic Respiration

Anaerobic Repiration

If the sugar that we just break down contains oxygen the that sugar falls to the aerobic respiration

If it does not contain sugar it goes to Anaerobic Respiration

Aerobic Respiration : It would use Kreb Cycle to Make 2 ATP.ATP is for Adension Tri Phosphate. Which is basically enregy.Then there comes Electron Transport Chain.Where they use protons to gain 32 ATP.Overall

2 ATp from glycolysis 2 from Kreb Cycle and 36 from ETC so 36

Anerobic: They fall part to 2 major respirations of this section which are

1. Alcoholic Repiration - It contains no oxygen, gain 2 atp and used to make breads and alcohol

2.Lactic Acid - gain 2 ATp and no oxygen and used  in yogurt you eat and it creates sore in your muscles

She is wrong because that is completely wrong statement that trees only do photosynthesis but no they use cellular Respiration to gain energy from ATP when there is no sun available to them

Hope that answers the question
