Climber Creeper
1. It readily climbs up to some
neighbouring support.
1. It creeps along the soil surface and
spreads on the ground over a long
distance.
2. It has special organs called tendrils for
climbing.
2. It does not have special organs like
tendrils for climbing.

17. Ans.
(i) The hip bones are called pelvic bones. They enclose the portion of our body
below the stomach. They constitute the part of our skeleton which we sit on. The
hip bones form a link between the upper part of the body and the legs.
(ii) The chest bones (ribs) and the backbone are joined to form a hollow, bony
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

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.

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.

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.

(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.

(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.
