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.
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.
The best time to water plants outside?
Late evening, when soil temperature is less and transpiration rate is lowered. Watering takes out soil air which affects the respiration by roots, hence the water uptake also.

Why is the rate of transpiration is not the same all time?

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.

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

What does the slope of a velocity vs time graph show you?
The rate of acceleration is a measure of the change of the velocity of an object with time. On a graph of velocity versus time, it is represented by the slope of the line so graphed. If velocity is changing in time, the object described is being accelerated. The greater the slope of the graph, the greater the change of velocity per unit of time and the greater the acceleration of that object. true
What happens to the displacement velocity and acceleration of an object as it falls through the air to the ground?
Displacement: Grows with time, at an increaing rate. Velocity: Grows with time, at a constant rate. Acceleration: Greater than zero, remains constant with time.
When do plants lose water?
all the time One way is transpiration.
