 Factors and multiples :

          1.) Find factors for 18:-

          Ans: First write the possibility of getting 18 in all tables  

For eg :- 1*18=18 

                2*9=18 

                3*6=18 

        Then the factors of 18 are 1,2,3,6,9 and 18 

          2.) Find multiples of 6 :-

      Ans: write all the tables of 6 in order 

              i.e 6,12,18,24,30,36,42,48,54,60

         3.) Find the  common factors of 24 and 30:-

       Ans: Firstly Factors of 24 are :-

             1*24=24

             2*12=24

             3*8=24

             4*6=24

            Secondly Factors of 30 :- 

            1*30=30

             2*15=30

             3*10 =30 

             5*6=30 

Here common Factors of 24 and 30 are 1,2,3,6 

           4.)  Find common  Multiples of 5 and 10 

            Ans: First multiples of 5 are: 

       5,10,15,20,25,30,35,40,45,50,55,60

                  Second multiples of 10 are: 

        10,20,30,40,50,60,70,80,90,100

So common Multiples of 5and 10 are 

         10,20,30,40,50,60

Solution to the above Question 

Learning objective:

By the end of this chapter, you will be able to-

• Define Seed, Parts of Seed, types of the seed
• Factor required for the seed to grow into new plant or sapling
• Define Germination & different stages
• Activities

Lets Recall:

Seed:

It is a part of a plant which sleeps inside a fruit; new plants grow from it when it gets proper condition. 

Let's do some experiments to look at what are all the factor necessary for the seed to grow.

Experiment 1:

Sow the seed on the soil and keep the seed on the floor

Observation:

The seed on the soil growing whereas seed on the floor remains same why it so?

Conclusion:

All the seeds need SOIL to give birth to a new plant.

Experiment 2:

You can place seed in the garden, but with the same seed in the darkroom.

Observation

The seed with light gives the new plant. But what about the seed without light why it so?

Conclusion

Sunlight is another factor necessary for the seed to give the new plant.

Experiment 3:

Place the pot with water pot without water.

Observation

The pot with water grows healthy and green, whereas the pot without water is not growing. Why it so?

Conclusion

Water is the basic and necessary factor for the seed to grow. By doing this experiment's will get to know that soil, water, sunlight and air are the fundamental factors required for the seed to give the new plant.

GERMINATION OF SEED AND STEPS INVOLVED:

Define Germination?

Germination is the process by which a plant grows from a seed.

The journey of seed to seedling passes through many early stages those will discuss in details.

1. When seed placed in moist soil, it absorbs the water around it, the water then reaches the beginning of the baby plant or the embryo within the seed. This makes the embryo grow and increase in size.
2. Eventually, the embryo brakes open the seed coat and come out of the seed.
3. The root comes out first and grows into the soil. This fixes the baby plant to the soil and helps root absorb water and nutrient from the soil.
4. Then shoot comes out of the seed and starts to grow towards the sun. The first pair of leaves come out of the seed with the shoot are called cotyledon.
5. the root grows longs the shot becomes green and sprouts more leaf this is a young plant is called seedling or sapling
6. Of all stages of germination, essential condition or factors are required.
