Solution: A flower bud is protected by green leafy structures called sepals. The 
sepals collectively form the calyx.  
 
2. Ans. Correct Option: [D] 
Solution: Vitamin D is synthesised by exposing the bare skin to morning sunlight. 
 
3. Ans. Correct Option: [D] 
Solution: Transpiration involves the release of water vapour from the leaves.

structure called the rib cage. The rib cage provides protection to some of the 
delicate internal organs of our body such as the heart, lungs and liver. It also 
takes part in breathing movements.

20. Ans. If we are sitting in a moving bus, then we are not changing our position in 
comparison to the things inside the bus. According to the definition of motion, we 
are not moving. The bus is moving. We can say that we are in motion in comparison 
to the outside trees and other buildings and stationary in comparison to things 
inside the bus. 
 
21. Ans. A white paper has a rough surface (as seen through a microscope), so it reflects 
the light falling on it in all directions, i.e. it causes irregular reflection. So, we cannot 
see our image in a white paper. 
 
22. Ans. Take a large sheet of cardboard and make a small pinhole in the middle of the 
sheet. Then, hold the sheet up in the Sun and let its shadow fall on a clear area. A 
small circular image of the Sun will be seen in the middle of the shadow of the 
cardboard sheet.

23. Ans. Roughage is the fibrous matter present in food which cannot be digested. 
? Functions of roughage: 
It provides bulk to the food, keeps the food and waste matter moving along the 
intestines and helps to prevent constipation. 
? Sources of roughage: 
Green vegetables, whole fruits and wholemeal flour products such as 
wholemeal bread, chapatti etc. 
 
24. Ans.  
(i) The leaves of the plant prepare food through the process of photosynthesis. 
During this process, the green leaves combine water and carbon dioxide from 
the air in the presence of sunlight and the green pigment chlorophyll to make 
food. Oxygen gas is released in the air.

(ii) Difference between reticulate venation and parallel venation: 
 
Reticulate venation Parallel venation 
1. The veins form a net-like design on 
both the sides of the midrib. 
1. The veins run parallel to one another 
on both the sides of the midrib. 
Examples: Marigold and Tulsi Examples: Sugarcane and barley 
 
25. Ans. 
(i) Bristles are tiny hair-like projections present on the underside of an 
earthworm’s body. They help the earthworm to get a good grip on the ground, 
which eventually helps in its movement. 
(ii) A snail moves around with the help of a large, disc-shaped muscular foot. The 
alternate expansion and contraction of the muscles of the foot produce a kind of 
wave effect. A series of waves bring about the gradual movement of the snail’s 
body.

(i) A pivot joint is a joint which shows movement in the form of rotation. In a pivot 
joint, a cylindrical bone rotates in a ring.  
Example: A pivot joint exists between our skull and the neck. It allows our head 
to bend ‘up and down’ and turn from ‘side to side’.

(a) Bones are hollow and light. 
(b) Bodies are streamlined and extremely light.

hard materials. Examples: Iron, glass  
Materials which can be easily compressed, cut, bent or scratched are called soft 
materials. Examples: Sponge, cotton 
 
28. Ans.  We can distinguish between cotton, wool, silk and synthetic fabrics by 
performing the 'burning test'. 
(i) If the piece of fabric burns vigorously with the smell of burning paper, then it is 
a cotton fabric. 
(ii) If the piece of fabric burns with the smell of burning hair, then it is a woollen 
fabric. 
(iii) If the piece of fabric burns with the smell of charred meat, then it is a silk 
fabric. 
(iv) If the piece of fabric burns slowly with the smell of burning plastic, then it is a 
synthetic fabric. 
 
29. Ans.  
(i) The needle of a sewing machine has periodic motion. 
(ii) metre (m): SI unit of length 
second (s): SI unit of time 
kilogram (kg): SI unit of mass 
 
30. Ans.  
(i) Emergency vehicles such as ambulances or fire engines use mirror images of the 
text written on them. This is done so that the driver of the vehicle in front of 
them reads the text correctly in the rear-view mirror and hence gives way to the 
ambulance or fire engine.                                           
(ii) The property of light travelling in a straight line in a medium is called rectilinear 
propagation of light.
