Question

♥ Write an experiment to show the movement of water molecules from roots to shoot. ♥


​

Answer 1

Required Experiment

Materials

3 glass or plastic cups (sturdy enough not to tip over)

300 g room-temperature water

Food coloring

Metric scale

Fan

Medium-to-large sealable plastic box (tall enough to fit an upright stalk of celery inside)

2 small squares of plastic wrap

2 stalks celery, leaves attached.

Procedure

Pick two celery stalks that they have similar amounts of leaves. (Hint: If you can’t find celery with leaves attached in your grocery store, buy a head of celery. The small inner stalks usually still contain leaves.) Cut off the bases of the stalks so that they are roughly the same height.

Place one glass on the scale and tare it: press the “zero” button so that the cup registers as “0 g”. Fill with 150 g of room-temperature water; gently place two drops of food coloring in the water; stir. Be careful not to spill any colored water! Repeat with the second glass.

Place one celery stalk in each glass, leaf–end at the top.

Wrap one square of the plastic wrap around the top of each glass and the celery stalk. This is to prevent any colored water evaporating into the air directly from the glass.

Answer 2

Answer:

Experiment

Aim :

To show the movement of water molecules from root to shoot.

Apparatus :

potted plant , tub, glasstube, clamp,

Procedure :

i) Take a regularly watered potted plant and cut the stem portion 1 cm above the ground level.

ii) Then connect a glass tube by means of strong rubber tubing.

iii) The size of glass tube should be equal to the size of the stem. Take care while joining tube and stem being bound tightly, so that water cannot escape from the tube.

iv) Now, pour some water in the glass tube until water level can be seen above the rubber tube.

v) Check the water level in the glass tube m1 and Mark it.

observation :

we can observe the increased water level m2 in the tube. The differences between m1 and m2 indicates the level of water raised in the stem.

Conclusion:

The water level in the tube increases due to Root pressure. This proves the movement of water molecules from roots to shoots in plants.
