Difference Between Photosynthesis and Respiration

Biology

The main difference between photosynthesis and respiration is that photosynthesis occurs during the day, and breathing occurs during the day and at night. Leaves (and other active metabolic tissues) breathe at night. They use oxygen to release carbon dioxide.

Low intensity at dawn and dusk. Therefore, the photosynthesis rate and respiratory rate become equal in a short time. Therefore, the amount of oxygen released by photosynthesis is equal to the amount of oxygen used to breathe cells.

Likewise, photosynthesis cells use the amount of carbon dioxide released by respiration. “Therefore, there is no net exchange of gas between the leaves and the atmosphere at this time. This is called the compensation point.” The rate of photosynthesis increases with increasing light intensity. Therefore, more carbon dioxide is needed. Carbon dioxide can only be provided by breathing.

Likewise, photosynthesis produces more oxygen than respiratory cells. Therefore, there is a net release of oxygen and carbon dioxide absorption.

Photosynthesis

Photosynthesis is a photochemical process in green plants that use sunlight to collect food or sugar in the presence of carbon dioxide, water, and chlorophyll in the green part of the plant. In this process, the light energy is converted into biochemical energy for sugar and other organic compounds, and oxygen is released.

Photosynthesis Procedure

In photosynthesis, the most important of them is water, as plants absorb hydrogen. In water, there must be some minerals that plants need. These compounds are mainly nitrogen, sulfur, phosphorous, potassium, calcium, magnesium, sodium, and iron compounds.

Plants obtain water and minerals from their roots. One of the reasons for long root tips is that they can stay in touch with new parts of the soil in search of minerals and water. Thousands of fine root filaments protrude from the surface of small roots, grow around soil particles and absorb matter.

Photosynthesis and Respiration

A portion of the water absorbed through the roots is used to make sugar. The rest stems from the leaves. When the water from the leaves flows faster than it penetrates from the roots, the plants will wither.

Respiration

Respiration is a process in which living organisms or cells use oxygen to analyze energy-rich organic compounds (such as glucose) to obtain energy to perform various cell activities. During this process, glucose is broken down and produced carbon dioxide.

Photorespiration and its Consequence

The respiratory activity that occurs in plants during the day is called photosynthesis. Therefore, photosynthesis is a process related to light. In this process, carbon dioxide is released and oxygen is absorbed. It absorbs oxygen from the early reaction of photosynthesis. This oxygen is not used for power generation, such as ATP.

The “carboxylase ribose diphosphate” or oxygen (Rubisco) enzyme works to repair oxygen during this process. In the Calvin cycle, Rubisco repairs carbon dioxide. Therefore, photosynthesis reduces the overall rate of carbon dioxide stabilization and plant growth (learn more).
