What will not affect the rate of transpiration?

External factors affecting the rate of transpiration are: atmospheric humidity, temperature, light, wind velocity, atmospheric pressure and available soil water. Chlorophyll content of leaves does not directly affect rate of transpiration.

How does sunlight affect transpiration?

Light intensity: The transpiration rate is increased due to the increase in light intensity. During daytime in the sunlight, the rate of transpiration is faster. This is because the stomata remains open to allow the inward diffusion of carbon dioxide for photosynthesis.

Why does light increase the rate of transpiration?

The evaporation of cells creates a negative pressure in the xylem, which pulls water upward.” Light increases the rate of water absorption and the resulting increased turgidity of the two guard cells, which form the boundary of each stoma, brings about the opening of the stomates, increasing transpiration rate.

How does darkness affect transpiration?

Darkness will cause the stomata to close causing a decrease in transpiration. Use a lamp. If less water is being lost through transpiration the plant will absorb less water at the roots.

On which factor does the transpiration loss also depends on?

On which factor does the transpiration loss also depends on? Explanation: Availability of moisture also affects the transpiration losses because plants transpire moisture according to its availability. That is plants transpire less moisture when moisture is scarce, and transpire more moisture when it is more available.

Why is translocation important to a plant?

It is an important process in plants because the source of production i.e., the location of photosynthesis is not the same as the site at which nutrients are stored; as a result it is essential that the nutrients be moved throughout the plant via translocation otherwise the food produced in the leaves will not be able …

What is the process of translocation?

The movement of sucrose and other substances like amino acids around a plant is called translocation . In general, this happens between where these substances are made (the sources) and where they are used or stored (the sinks): from sources in the root to sinks in the leaves in early spring time.

What is difference between transpiration and translocation?

Transpiration is the water evaporation in the form of water vapour from the leaves. Transpiration primarily includes the xylem cells that become effective by the roots during the absorption process. Translocation involves both xylem and phloem cells to carry the synthesized food materials inside the plant.

What is the cause of transpiration?

Transpiration is caused by the evaporation of water at the leaf–atmosphere interface; it creates negative pressure (tension) equivalent to –2 MPa at the leaf surface. Evaporation from the mesophyll cells produces a negative water potential gradient that causes water to move upwards from the roots through the xylem.

What is translocation in plants Class 10th?

Transport of soluble product of photosynthesis or food from leaves to other parts of plants is called translocation. For translocation, food molecules enter the part of the phloem called the sieve tubes where they can be transported upwards or downwards to all parts of the plant including roots.

What is translocation answer?

Answer: Translocation is a biological mechanism involving the transfer of water and other soluble nutrients from one part of the plant to another through the xylem and phloem, which occurs in all plants.

What is translocation and how does it occur?

Translocation is the movement of materials in plants from the leaves to other parts of the plant. Nutrients, mainly sugars, are created in the leaves during photosynthesis. These are then transported throughout the plant through phloem, which are a long series of connected cells.

What is translocation in human body?

Translocation is a type of chromosomal abnormality in which a chromosome breaks and a portion of it reattaches to a different chromosome. Chromosomal translocations can be detected by analyzing karyotypes of the affected cells.

What is the path of the translocation of the food in the plant?

Food is prepared in plant leaves during photosynthesis. It is then transported to all the parts of the plant through vascular tissues called phloem. Transport of food in phloem is bi-directional, i.e. it moves both upward and downwards.
