There would be more light-induced damage to the cells.

Plants deficient in photorespiration would likely exhibit reduced growth and productivity due to impaired carbon dioxide and energy metabolism. They may also show increased sensitivity to environmental stresses such as high temperatures and drought due to the role of photorespiration in stress tolerance. Ultimately, the overall fitness and survival of these plants could be compromised.

Can tomato plants show photo respiration?
No, tomato plants do not undergo photorespiration. Photorespiration is a process that occurs in C3 plants, where oxygen is mistakenly used instead of carbon dioxide in the initial steps of photosynthesis. However, tomato plants are classified as C4 plants, which have evolved mechanisms to minimize photorespiration.
Does photorespiration produce energy?
No, photorespiration does not produce energy. In fact, it is considered a wasteful process that occurs in plants when there is a lack of carbon dioxide and excess oxygen in the leaf cells. Photorespiration can decrease the efficiency of photosynthesis in plants.
Is photorespiration independent of light intensity?
Photorespiration is not independent of light intensity; it is suppressed at high light intensity due to the greater availability of CO2 for photosynthesis. Under low light conditions, photorespiration can become more prevalent as there is a higher ratio of oxygen to CO2 in the leaf, leading to increased oxygenation of ribulose bisphosphate.
What organisms have the greatest problem with photorespiration?
C3 plants, such as wheat, rice, and soybeans, have the greatest problem with photorespiration due to the inefficiency of the enzyme RuBisCO at fixing carbon dioxide. This leads to loss of energy and resources in the plant.
Which situation best accounts for photorespiratin in plants?
Photorespiration is more likely to occur in plants when the ratio of oxygen to carbon dioxide is high, such as in hot and dry environments. This leads to Rubisco, the enzyme involved in photosynthesis, fixing oxygen instead of carbon dioxide, resulting in the wasteful process of photorespiration.

What is photorespiration?
Photorespiration is a process in plants that occurs when rubisco, the enzyme responsible for carbon fixation, uses oxygen instead of carbon dioxide. This can happen in hot or dry conditions, leading to a wasteful process that reduces the efficiency of photosynthesis. Photorespiration can lower the productivity of plants.
What are the advantage and disadvntage of photorespiration?
Advantage: Photorespiration helps to salvage energy and prevent damage to the plant from reactive oxygen species. Disadvantage: Photorespiration decreases the efficiency of photosynthesis by wasting energy and reducing carbon fixation, ultimately leading to lower yields in plants.
How do you increase photorespiration?
There is no need to increase photorespiration . It is an injurious process for plants . It is increased by strong sun light and high temperature as it happens at mid day .It specially happens in tropical regions .
Why C4 plants able to photosynthesize with no apparent photorespiration?
C4 plants have an additional carbon fixation step involving PEP carboxylase, which helps to concentrate CO2 around Rubisco, reducing the likelihood of oxygen competing with CO2 at the active site of Rubisco. This spatial separation of carbon fixation and the Calvin cycle enables C4 plants to minimize photorespiration.
What happens to the plant if it is deficient in phosphates?
potassium deficient plants have brown scorched blooking leaves
What will happen if the soil is deficient of plant nutrients?
The plants will not grow as well, as large, or as healthy as they would otherwise. The crop yield will probably be lower as well.
Why doesn't photorespiration occur in chemoautotrophs?
Photorespiration occurs in plants because they use oxygen in the Calvin cycle, leading to the wasteful process. Chemoautotrophs do not utilize the Calvin cycle for carbon fixation; instead, they use alternative pathways like the reductive tricarboxylic acid cycle or the 3-hydroxypropionate bi-cycle. This means that they do not produce the same conditions that lead to photorespiration as seen in plants.
