What is compensation point in plants?
Compensation Point for Light (of photosynthetic plants) is the intensity of light at which the rate of carbon dioxide uptake (photosynthesis) is exactly balanced by the rate of carbon dioxide production (respiration) or equivalently, the light intensity at which the rate of oxygen production is exactly balanced by the …
What is the importance of translocation in plants?
Because translocation is responsible for the delivery of nutrients to developing seeds and fruits, this process is critical to the achievement of optimal crop yield. It also accounts for the ultimate nutritional composition of plant foods important to humans.
What happens at the compensation point?
The Compensation Point is the point at which Photosynthesis and Respiration are in balance, so (in a perfect world) the amount of oxygen being produced by photosynthesis will just balance the amount being used by respiration. At this point there will be NO oxygen bubbles being produced in the leaf discs.
What is compensation point when does it occur in plants?
Timing. The compensation point is reached during early mornings and late evenings. Respiration is relatively constant, whereas photosynthesis depends on the intensity of sunlight. When the rate of photosynthesis equals the rate of respiration or photorespiration, the compensation point occurs.
What is the compensation point and why is this important to know for living organisms?
The compensation point is reached when the gross productivity of a producer is equal to the amount it must consume in respiration to stay alive. At the compensation point the net productivity is zero, and no growth can occur. Each bottle represents the net productivity of the algae at a different depth.
What is translocation and its importance?
Translocation in plants occurs in the vascular tissue known as phloem. Translocation is the movement of materials from leaves to other tissue throughout the plants. Without translocation, the food prepared by the plant can’t reach other parts of the plant.
What is the importance of transpiration and translocation in plants?
Transpiration through leaves is usually regarded as one of the important motive forces behind the translocation of nutrients, because transpiration promotes the uptake of minerals including Cd from the soil along with water.
How does translocation help in the plant growth process?
Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks. … The pattern of photosynthate flow changes as the plant grows and develops.
Do plants grow at compensation point?
Photosynthesis, in contrast, occurs only in light and uses up carbon dioxide and makes oxygen. There is a light intensity at which respiration and photosynthesis cancel each other out. This is called the compensation point. Below this level carbohydrates are used up and the plant cannot grow.
What is compensation point in biology class 10?
What is compensation point? Answer: When the rate of photosynthesis is equal to rate of respiration, it is called as compensation point. The rate of liberation of O3 during photosynthesis is equal to the rate of liberation of CO2 during respiration.
