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.
