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 does mechanical advantage differ from ideal mechanical advantage?
Mechanical advantage is determined by physical measurement of the input and output forces and takes into account energy loss due to deflection, friction, and wear. The ideal mechanical advantage, meanwhile, is the mechanical advantage of a device with the assumption that its components do not flex, there is no friction, and there is no wear.
How many times force is multiplied is the mechanical?
In a mechanical advantage system, the force is multiplied by the factor of the mechanical advantage. The formula for mechanical advantage is MA = output force / input force. This means the force can be multiplied by the mechanical advantage value.
How can time be used to measure mechanical advantage?
Time can be used to measure mechanical advantage by comparing the time taken to perform a task with and without a mechanical advantage device. If a mechanical advantage device reduces the time required to complete a task, it indicates that the device has increased the efficiency of the task, thereby providing mechanical advantage.
The amount by which a machine multiplies an input force is called?
The amount by which a machine multiplies an input force is called mechanical advantage. It is calculated by dividing the output force by the input force.
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
Advantages and disdvantages of formal organization?
disadvntage of informal organization
What is the disadvntage of a three phase system?

Where is Photorespiration located?
Photorespiration involves three different organelles--- chloroplasts, peroxisomes and mitochondria
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.
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.
Why is photorespiration such a waste?
Photorespiration is a wasteful process because: i. About 25 % of the CO2 fixed during photosynthesis is lost ii. There is no formation of ATP & NADH
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 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 happens during photorespiration?
In photorespiration, O2 replaces CO2 in a non-productive, wasteful reaction. Photorespiration occurs when the CO2 levels inside a leaf become low, which happens on hot dry days when a plant is forced to close its stomata to prevent excess water loss.
Photorespiration does not produce energy in any form?
True!
Does photorespiration produce energy in any form?
True
What is the another to carbon dioxide for the function it performs?
