Question

4. Activity Time: See the picture below and do the activity with Rajma seeds at your home.
Soak the rajma seeds and observe the different stages day by day.
Write what you observed in the space given below.
Seed
Sprout
Sapling
Plant​

Answer 1

Answer:

the rajma seed first grows to a sprout by having a green small stem out of it. It increases in size and has leaves on it and thus changes into sapling this sapling further grows into plant.

Explanation:

thank if you think its useful

Answer 2

Answer: After soaking the rajma seeds the stages can be observed as follows :

1. DAY 1 - The rajma seeds swell up
2. DAY 2 - Sprouts appear in the seed
3. DAY 4 - Saplings grow
4. DAY 10 - Plant grow out of the seed

Explanation: The following activity demonstrate the process of germination in the rajma seed.

The activity can be explained as :

• AIM :  To demonstrate the process of germination process in the rajma seed.
• REQUIREMENTS : Beaker, water, rajma seed.
• PROCEDURE : Take some water in a beaker and soak some rajma seeds in it. Leave it undisturbed for a day.
• OBSERVATION : The observations for each day is different :

1. DAY 1 - On the very next day, the soaked seeds swell up.
2. DAY 2 - Sprouts grow as the next stage of the germination process.
3. DAY 4 - Saplings appears on the 4th day.
4. DAY 10 - A baby plant grows in the span of 10 days since the soaking of the seed.

• CONCLUSION : The conclusion for each observation can be stated as :

1. DAY 1 : The seed swells up as it absorbs the water by the process of osmosis.
2. DAY 2 - As of now, the seed have enough water and air supply to enter into the next stage of germination where sprouts starts growing.
3. DAY 4 - The next stage is the growth of a sapling from the germinated sprout.
4. DAY 10 - After a long process of germination, the sapling grows into a plant.

NOTE : The germination period differs for the different plants.
