In what cellular organelle does aerobic respiration take place in a plant?

To answer this question, let’s have a look at some of the cellular organelles that can be found in a typical plant cell. Plant cells, in contrast to animal cells, have a cell wall, which gives the cell stability and protection. Most plant cells also contain a large, permanent vacuole, which stores water, food for later use, enzymes, and waste products for removal. Many plant cells also contain chloroplasts, which are responsible for producing sugar in the form of glucose through a process called photosynthesis. This sugar is one of the key reactants needed for aerobic respiration.

During aerobic respiration in plants, glucose and oxygen are converted into carbon dioxide and water. This process releases energy, which is stored in the form of a molecule called ATP so that the energy can be very easily accessed when it is needed. When respiration occurs in the presence of oxygen, it is specifically referred to as aerobic respiration. This process takes place in cellular organelles called mitochondria, one of which is called a singular mitochondrion.

Now we know the correct answer to our question. The cellular organelle in which aerobic respiration takes place in a plant cell is the mitochondrion.
