NEET BIOLOGY

Detailed explanation-1: -A potometer is a piece of apparatus designed to measure water uptake in a leafy shoot. There are 2 types of potometer – the bubble potometer and the weight potometer.

Detailed explanation-2: -A potometer or transpirometer is a device used to measure the rate of water uptake of a leafy shoot. The causes of water uptake are photosynthesis and transpiration. There are two main types of potometers the bubble potometer and the mass potometer.

Detailed explanation-3: -A potometer is a piece of apparatus that is used to measure water uptake by plants. Most of the water taken up by plants replaces water lost in transpiration. A student used a potometer to investigate the effect of wind speed on the rate of water uptake by a leafy shoot.

Detailed explanation-4: -This process is known as osmosis. Using a piece of apparatus called a manometer, the student can measure the hydrostatic pressure generated by the root when water passes into the plant by osmosis. Over a two-hour period pressure increases, forcing the blue liquid up the right-hand side of the manometer tube.
