Solar radiation in plants inhance the rate of transpiration. To cope up with the water deficiency in plants roots are desired to uptake more water.
A potmeter is a something that is used for measuring the rate of water uptake in a leafy shoot. The causes of water uptake are photosynthesis and transpiration.Soz but this is all i got. i hopped there would be something on here but no. If any one has got more information about it ADD IT!!!
Overcrowded plants have to compete with neighboring root systems for water as well as nutrients.
A Large Mineral Uptake
If you are referring to a the rate of water uptake in plants, then a live plant stem is placed in one end of the uptake photometer which is filled with water by a reservoir and tap. at the other end of the photometer there is a scale with an air bubble. Over time, as the plant takes in water, the air bubble will move along the scale and this can be used to work out how much water the plant is using. dont know if this will be of any help :)
it causes the water to move with it
by itself
water uptake at the roots is called osmosis,this is the movement of water molecules from a region of lower concentration to a region of higher concentration against concentration gradient
Potometer
To follow the Law of diffusion.
You can't get disability for radiotracer uptake if the amount is calculated properly and if you drink good amounts of water after the medical analysis.
