rectangular and arranged in rows. Each cell had a thick boundary and a dense,
round structure in the centre. Later, she examined cheek cells and found them
irregular in shape but also had a prominent central structure. (a) What is the dense, round
structure Riya observed in both onion and cheek cells, and what is its
primary function? (b) What is the difference
between the outer boundary of onion cells and cheek cells, and why is there a

Case
study Based Questions (4 marks each) Rutherford
(1871-1937) was known as the ‘Father’ of nuclear physics. Ernest Rutherford
was interested in knowing how the electrons are arranged within an atom.
Rutherford designed an experiment for fast moving alpha (α)-particles were
made to fall on a thin gold foil. On the basis of his experiment, Rutherford
put forward the nuclear model of an atom, which had the following features: There
is a positively charged centre in an atom called the nucleus. Nearly all the
mass of an atom resides in the nucleus. The
electrons revolve around the nucleus in circular paths. The
size of the nucleus is very small as compared to the size of the atom. Drawbacks
of Rutherford’s model of the atom: The revolution of the electron in a
circular orbit is not expected to be stable. Any particle in a circular orbit
would undergo acceleration. During acceleration, charged particles would
radiate energy. Thus, the revolving electron would lose energy and finally
fall into the nucleus. If this were so, the atom should be highly unstable
and hence matter would not exist in the form that we know. We know that atoms
are quite stable. (1)

Objects having density more
than that of liquid in which they are immersed, sink on the surface of the
liquid. A block of wood is floating on water while an iron nail sinks when
placed in water. The teacher explains that this is due to the difference in their

an object to float in a liquid? b) What is buoyant force? c) Why does the iron nail
sink in water? d) Which principle explains
the floating and sinking of objects in fluids? |
