CLASS 5
CH - 1 GROWING PLANTS

Hello Class
Congratulations! and wish you all a great year ahead.
I am Ms. Preeti Joseph, your class teacher for the year 2020-21.

I hope you enjoyed your class yesterday.
You have already learnt the following :

• Journey from a seed to plant.
• Parts of a Seed.
• Structure of a Seed. 

Today we will learn about Germination and Dispersal of Seeds.

Let's watch a video and understand how a seed germinates and what are the essential conditions required for seeds to germinate.
Length of the video (5 mins 27 secs)




I hope you enjoyed the video.

Following are some important points to remember.

Conditions required for the growth of a seed are :

• Moisture
• Warmth
• Nutrient rich soil
• Sunlight
• good quality seed

Once the above conditions are satisfied, the seed begins to grow.

The seed 

• absorbs water from the soil.
• and provides moisture to the embryo.

1. The plant cell inside the seed start duplicating.
2. Enzymes gets activated.
3. Embryo starts getting nourishment and starts growing.
4. Growing plant bursts open.
5. Roots start growing downwards to anchor the seed.
6. Food and nutrients from the soil help the root to grow.
7. The shoots start growing upward towards the light.
8. Here's our baby plant with tiny leaves.

This process of the growth of a seed into a plant is called germination.

It's now time for a quick recap.

1. ___________________, _______________________and ____________________ are the conditions required for the growth of a seed. (write any three)

2. The change of seed into a seedling is called _______________________.

3. The roots act as an ___________________ to the seed.

4. The ________________grow upward towards the __________________.

5. The seed absorbs water from the _________________.

6. ___________________and ___________________ from the soil help the root to grow.

That's all for today.

I hope you enjoyed the class.

Happy learning. God bless!!
