Answer:
Uses of wood :

1. Indeed the things made of wood are en vironmentally eco – friendly products.
2. Wooden items do not cause harm to the environment.
3. To make the items with wood, we should depend on forests and domestic plants.

Demerits of cutting trees :

1. Cutting trees for wooden items severely affects the decrease in forests and all the plantations is called deforestation.
2. Deforestation leads to imbalance in nature and there will be a decrease in rainfall.
3. Oxygen in the atmosphere decreases.
4. Deforestation causes top most soil erosion. Thus in turn it results in losing of soil fertility. Due to soil erosion we lose food grain harvestation.

Alternative steps to avoid cutting trees for wooden items :

1. One way is to grow the wood giving plants in the waste land areas with the help of our society.
2. The wooden furniture, once we purchase them from the shop, should be used them without damage.
3. We should not cut down non-wood giving trees along with wood giving plants unnecessarily.
4. We have to find a solution to convert any waste and already used material into wooden like furniture.

Answer:

1. Applying the magnetic property for making a toy magnet to conduct the programme is interesting.
2. The junk food box is placed on one side of the table. Good food box is kept on the other side.
3. Each item of the junk food with bar magnet facing its specific pole is arranged. Likewise to the good food items having magnet facing its specific pole.
4. Moving the toy magnet in front of junk food, keeps away from them. Because of the facing pole of the toy magnet is as same as pole of the junk food items.
5. Moving the toy magnet in front of the good food items, attract them, because of unlike poles of the food items magnet and toy  magnet. We should emphasise the magnetic property of the two bar magnets in our day to day life. To conduct an awareness programme on food items, toy magnet game will be very interesting.

TS 6th Class Science Important Questions 9th Lesson Plants: Parts and Functions

Question 1.
What is venation ? What is its use?
Answer:
The arrangement of veins in the lamina of leaf is called venation. Venation acts as a skeleton of the leaf and gives it a shape and support.

Question 2.
What is transpiration?
Answer:
Plants release excess water in their body through stomata and some other parts as well. This water is released in the forms of vapour and this process is called transpiration.

Question 3.
What are the functions of root?
Answer:
Roots absorb water and minerals from the soil and also help in anchoring the plant body to the soil.

Question 4.
Name the types of venations we see in the plants.
Answer:
There are two types of venations in different plants.

• Reticulate venation
• Parallel venation

Question 5.
How many types of roots are present in plants and name them.
Answer:
There are two types of root systems.

• Tap root system
• Fibrous root system

Question 6.
What happens when stomata are not present in leaf?
Answer:
If stomata are absent in leaf plants cannot take carbon dioxide which is useful for preparation of food.
Excess of water taken by plants cannot he expelled out. Exchange of gases will be stopped. As a result plant cannot perform its functions.

Question 7.
What would happen if there are no veins in the leaf?
Answer:
If veins are absent the leaves would lose their specific shape and support from the stem. The food that is prepared in the leaf cannot be supplied to the other parts of the plant. The water and minerals coming from the roots (via) stem cannot reach the leaves due to absence of veins.
