What else can I help you with?
Why is the rate of transpiration not same all the time?
Because sometimes you walk fast and sometimes you walk slowly.
How does humidity affects the rate of transpiration?
Transpiration rates decrease proportionally to the amount of humidity in the air. This is because water diffuses from areas of higher concentration to areas of lower concentration. Thus, when the air spaces between the mesophyll cells in a leaf are saturated with water vapor, and the air outside the leaf is likewise saturated, there is a shallow gradient. A shallow gradient results in a slower transpiration rate. Conversely, if the air outside the leaf is relatively dry, the gradient becomes steep and the rate of transpiration increases.
What is the formula for transpiration?
The formula for transpiration is: Transpiration = (Amount of water transpired) / (Area of leaf surface) * (Time taken)
Stomata in a sentence?
Plants use transpiration to exchange gases. We studied transpiration in science.
How light intensity affects transpiration?
light, along with carbon dioxide and water allows photosynthesis to happen, producing glucose and oxygen. therefore, the glucose created may allow the plant to transpire? so im thinking the light along with carbon dioxe and water equally affects the activity of transpiration, using the energy made by photosynthesis. i may not be correct as im year10, and i just briefly read the definition of transpiration, but that's what i think. EDIT: College student Carbon dioxide and light are necessary for photosynthesis to occur. Plants have specialized structures known as stomata, essentially tiny little mouths, that open up in order to allow carbon dioxide to enter the plant. The problem is, plants also really need water, and when stomata are open, water leaks out the tiny little holes. It wouldn't be very efficient to keep the stomata open all the time, as the plant would constantly be losing water. For that reason, plants only open their stomata when all the conditions are right for photosynthesis. If light and CO2 are missing, the stomata stay closed and the plant gets to keep its water. If light and CO2 are present, the stomata open and photosynthesis begins. Transpiration is defined by water loss through the leaves of a plant, so it makes sense that it would go way up when the stomata are open. Transpiration rate increases with light intensity.

What is a definition of the rate of transpiration?
Hard to answer because transpiration rate is affected by many factors.This is from wikipediaThe rate of transpiration is directly related to the degree of stomatal opening, and to the evaporative demand of the atmosphere surrounding the leaf. The amount of water lost by a plant depends on its size, along with the surrounding light intensity, temperature, humidity, and wind speed (all of which influence evaporative demand). Soil water supply and soil temperature can influence stomatal opening, and thus transpiration rate.Maybe you mean what is a definition of transpiration rate?Transpiration rate i.e. the rate at which water is lost by a plant. Water can be lost from various parts of plants especially leaves but also stems, flowers and roots.
What is a higher birth rate?
A higher birth rate is a rate of reproduction greater than the current norm, or average, or a rate of reproduction greater than a norm or average at a given time.
How does humidity affects the rate of transpiration?
Transpiration rates decrease proportionally to the amount of humidity in the air. This is because water diffuses from areas of higher concentration to areas of lower concentration. Thus, when the air spaces between the mesophyll cells in a leaf are saturated with water vapor, and the air outside the leaf is likewise saturated, there is a shallow gradient. A shallow gradient results in a slower transpiration rate. Conversely, if the air outside the leaf is relatively dry, the gradient becomes steep and the rate of transpiration increases.
Why is the rate of transpiration is not the same all time?
Because sometimes you walk fast and sometimes you walk slowly.
How do you write the result of transpiration experiment?
To write the result of a transpiration experiment, include the measurements of water loss over time from the plant samples. You can present the data in a table or graph format, showing the relationship between variables such as humidity, temperature, and transpiration rate. Conclude with a summary of trends observed and any significant findings from the experiment.
What is the formula for transpiration?
The formula for transpiration is: Transpiration = (Amount of water transpired) / (Area of leaf surface) * (Time taken)

What factors effect the rate of transpiration?
Humidity - increased humidity decreases transpiration, as the air is already saturated with water, and so the water potential gradient is smaller, and so less water is lost by transpiration. Temperature - increased temperature increases transpiration as the water has a greater kinetic energy and so there is more evaporation of water. Wind/air movement - in still air, a shell of highly saturated air surrounds the air, decreasing the water potential gradient and decreasing transpiration rate, but wind destroys this shell of saturated air so there is a bigger water potential gradient, amd more transpiration. Light intensity - light is needed for the stomata to open - they do not open at night time (unless the plants are xeromorphically adapted desert plants or plants living in other harsh environments such as salt marshes). Internal factors that affect transpiration are the number of stomata, leaf area, the cuticle (thick waxy cuticles prevent water loss, whilst thinner and less waxy cuticles allow more water to be lost. Distribution of stomata also affects transpiration - most plants have most of the stomata on the lower surface of the leaf where the stomata are less exposed to environmental conditions.
What does it mean death rate?
The number of deaths occurring in a particular area at a period of time is said to be the death rate of the particular region. For example, the death rate in India is greater than that of the birth rate.
What is the differences between transpiration and guttation?
Water leaves as vapor in day time in transpiration. Salty water leaves as liquid at night in guttation
Why would a sack of rice and a poly-tin bag fall at the time?
all objects in a vaccum would accelerate at the same rate, striking the ground at the same time. in air consider two table tennis balls , one full of lead , dropped at the same time, initial acceleration is the same, in motion at same speed air resistance force is same but lead ball has greater force (f=ma) due to greater mass, force down is greater in lead ball, acceleration is greater , top speed will also be greater, will arrive at ground first
