Germination Experiment

Q.

Take two beakers and mark them A and B. In beaker A, place some seeds of green gram on dry cotton wool. In beaker B, place some seeds of green gram on moist cotton wool. Keep both the beakers in an ordinary room. What will be observed by the end of the process?

1. Seeds in beaker A will germinate, but seeds in beaker B will not germinate

2. Seeds in both the beaker A and B will not germinate

3. Seeds in beaker B will germinate but seeds in beaker A will not germinate

4. Seeds in both the beaker A and B will germinate

Q.

Take two beakers and name them A and B. Place some green gram seeds on moist cotton wool in each of two beakers. Keep beaker A in the refrigerator and beaker B in an ordinary room. What will you observe this process?

1. Seeds in beaker B will germinate, but seeds in beaker A will not germinate

2. Seeds in both the beaker A and B will germinate

3. Seeds in beaker A will germinate, but seeds in beaker B will not germinate

4. Seeds in both the beaker A and B will not germinate

Q. Germinated seeds are considered highy nutritive what is the reason for this belief

Q.

Three matured air dried bean seeds are taken and tied to a glass slide at three positions as shown. This slide is kept in a beaker containing water in a manner that the top seed is well above water, the middle one is just at the water level and the bottom one is deep in water. The experimental set up is left in warm place for few day. What will you notice by this processes?

1. The middle will germinate, the top will not germinate and the bottom one stops germinating after the emergence of the radicle.

2. Top, bottom, and middle will germinate

3. Top and middle will germinate and the bottom does not germinate

4. Bottom and top will germinate and the middle one does not germinate

Q.

here r 4 containers and Dry cotton wool is placed at the bottom of each container each of them r same sizes:

(a) Soaked bean seeds are kept in the container A and a few drops of water are added daily to moisten the cotton - wool. what will u notice after few days?

(b) Soaked bean seeds r placed in container B but the cotton wool is not moistened. what u notice after few days?

(c) Unsoaked bean seeds r placed in container C without adding water . what u notice in this after few days ?

(d) Soaked seeds r placed in container D water is added sufficiently to submerge the seeds .

in all d containers A<B<C<D an equal no. of seeds from the same lot r kept in the same conditions of light and temperature.

what conclusions would y draw from the results given above.

Q. The seeds respirate at the time of germination. While showing this experiment a test tube with $KOH$ is kept in the conical flask to ______

1. Supply oxygen necessary for respiration.
2. Create space in the conical flask by absorbing CO2.
3. Absorb water from the seeds and dry them.
4. Make the air in the conical flask, acidic
