(c) nerve cell.
(d) parenchyma.

2. A student identified the following figure as striped muscles
because of
(a) light and dark striations and is uninucleated.
(b) light and dark striations and is multinucleated.
(c) has no striations and is uninucleated.
(d) has no striations and is multinucleated

3. Smooth muscle fibres are
(a) spindle shaped, unbranched, non-striated, multinucleate and involuntary.
(b) spindle shaped, unbranched, unstriated, uninucleate and involuntary.
(c) cylindrical, striated unbranched, multinucleate and voluntary.
(d) cylindrical, unbranched, non-striated, multinucleate and involuntary.

4. Observe the location and
shape of the nuclei in the four
drawings of the striated muscle
fibres given. The drawings that
most resembles the slide of
striated muscle fibre under the
microscope is
(a) A
(b) B
(c) C
(d) D
5. Aditi observed following observations while looking into a permanent slide.
1. Cells are long and cylindrical.
2. Light and dark bands are present giving striated appearance
It could be a
(a) slide of striated muscle fibre.
(b) slide of smooth muscle fibre.
(c) slide of neuron.
(d) slide of parenchyma cells.
6 On observing a permanent slide under the microscope, a
student found the structure without cell wall. It had light and
dark bands. The slide could be of
(a) nerve cell.
(b) striated muscle.
(c) parenchyma.
(d) unstriated muscle.
