Difference between perspiration and translocation

The main difference between transpiration and translocation is that transpiration is a process that takes place when water evaporates from the leaves of plants in the form of vapors, while translocation is the transport of minerals and synthesized products within the plant to different areas …

Perspiration versus translocation

Transpiration is a process of evaporation of water from plant leaves in the form of water vapors, while translocation is the process of transporting minerals and synthesized products within the plant to different areas. In perspiration, water vapors evaporate from plant leaves; its direction is always against gravity; however, translocation can take place in the direction of gravity or in the opposite direction, since it is the transport of minerals and synthesized products within different parts of the plant.

Perspiration involves only the xylem cells to carry out the perspiration process; on the other hand, the translocation process can be carried out by both the xylem and phloem cells of plants to carry out their transport. Transpiration is a process of water evaporation and therefore involves only water as a carrier, on the other hand, translocation is a process of transporting synthesized products within the plant and therefore involves synthesized products such as sucrose. .

Perspiration requires sunlight to carry out its process of evaporation of water, since the stomata open only in the presence of sunlight, and thus the process of perspiration takes place; Contrary to this, translocation does not involve stomata to carry out the transport process, so it can be carried out by plants during the day or at night, that is, in the absence of sunlight.

Transpiration requires a stomatal opening in plant leaves to evaporate water vapors from plant leaves, while translocation does not require stomatal openings as it is an internal transport process. Transpiration is a process that impacts the surrounding environment by cooling the temperature, while translocation does not involve the evaporation of water as an internal process of a plant and does not impact the external environment of its process.

Comparative chart

Perspiration is known as a movement of water vapors through the stomata of the leaves into the atmosphere. It is an essential process that must take place through the leaves of the plants. Atmospheric humidity is part of this evaporation carried out by plants. Approximately it is estimated that this process contributes around 10% of the total humidity in the atmosphere. Stomata are present on the underside of the leaves.

Plants also regulate perspiration to cope with drought and extreme drought situations. These stomata have their main importance here, since they modulate the perspiration process by adjusting the size of their opening. Cells that participate in regulating the size of open pores are called guard cells. It is also similar to the evisceration process in which some plants excrete the xylem sap in the lateral curves of the leaves.

The xylem cells of plants transport evaporated water from the soil through pathway cells. This water is useful in the photosynthesis process. The residual water from the photosynthesis process evaporates from the stomata of the leaves. It can also occur through stoma cells on the stems. Perspiration acts as a primary pulling force, helping to create flow in the vessels, which then aids in the transport of fluids through the translocation process. Thus, it allows the plant to take in more minerals and nutrients from the soil along with the water.

What is translocation?

Translocation refers to the process of movement of nutrients and synthesized products from plant leaves to other parts of the plant body. Plants produce organic substances within their leaves through the process of photosynthesis. Glucose is the result of the photosynthesis process, which is then converted to sucrose for temporary storage.

During the photosynthesis process during the day in the presence of sunlight, this sucrose is continuously piled up for temporary storage. Then at night this stacked sucrose is loaded into the phloem. This phloem then carries the sucrose throughout the body of the plant. This sucrose and other organic components that are transported by the phloem are called assimilates.

The assimilates are loaded by the phloem at the source and then these are released into the sink. The elements of the phloem sieve transport the assimilated. By joining the ends with the elements of each sieve, they form a direct current. It leads to a decrease in the water potential of the strainer element at the source as it actively assimilates the charge at the source. As water enters the sieve cells from the xylem, the pressure inside the sieve element increases and pushes the contents through the column. At the sink location, this process differs as assimilate removal, the pressure here is reduced in the column. This pressure difference leads to the flow of assimilates and acts as a driving force for the passage of these components.

Translocation is the process of transporting minerals and synthesized products within the plant to different areas that can take place in or in the opposite direction to gravity, such as the transport of minerals and synthesized products within different parts of the plant. The translocation process can be carried out by both the xylem and phloem cells of plants to carry out their transport. It is an internal process of transport of synthesized products in plants that involve synthesized product such as sucrose.

Key differences

1. Perspiration is a process of evaporation of water, while translocation is the process of transporting minerals and synthesized products.
2. In perspiration, when water vapors evaporate from plant leaves, their direction is always against gravity; however, the translocation can take place in any direction in or opposite to the direction of gravity.
3. Perspiration involves only the xylem cells to carry out the process; on the other hand, the translocation process can be carried out by both the xylem and phloem cells of plants to carry out their transport.
4. Perspiration is a process that involves only water as an ingredient; on the other hand, translocation is a transport process and therefore involves synthesized products such as sucrose.
5. Perspiration requires the presence of sunlight to carry out its water evaporation process successfully; Contrary to this, translocation does not require sunlight to carry out the transport process; That is why it can be carried out by plants during the day or at night.
6. Transpiration requires a stomatal opening in plant leaves for evaporation of water vapors from plant leaves, while translocation does not require stomatal openings as it is an internal transport process.
7. Perspiration impacts the surrounding environment by cooling the temperature, while translocation does not involve evaporation of water; therefore, it does not impact the external environment of your process.

Final Thought

Transpiration is a process that takes place in the presence of sunlight as water evaporates from plant leaves in the form of vapors, while translocation is the process that does not require sunlight and involves the transport of minerals. and synthesized products within the plant to different areas.
