Plants have a branching shape, so they have quite a large surface area in comparison to their volume. Therefore, diffusion alone can supply all the cells of the plants with as much oxygen as they need for respiration.
Diffusion occurs in the rots, stems and leaves of plants.
Respiration in Roots:
Air occurs in soil interspaces. Root hairs of the roots are in direct contact with them.
Oxygen of the soil air diffuses through root hair and reaches all internal cells of the root for respiration.
Carbon dioxide produced by root cells diffuses in the opposite direction.
In water-logged conditions, soil air becomes deficient. In the absence of oxygen, metabolic activity of the root declines and the plant may wither.
Respiration in Stems:
The stems of herbaceous plants have stomata. The oxygen from air diffuses into the stem of a herbaceous plant through stomata and reaches all the cells for respiration.
The carbon dioxide gas produced during respiration diffuses out into the air through the same stomata.
In woody stems, the bark has lenticels for gaseous exchange.
Respiration in Leaves:
The leaves of a plant have tiny pores called stomata. The exchange of respiratory gases in the leaves takes place by the process of diffusion through stomata.

The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. ...Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration
