The cell body / cyton and the dendrites contain nissl's granules. They are absent in the axon.

Multipolar and bipolar neurons differ in
1 Number of cytons
2 Presence or absence of Nissl's granules
3 Number of dendrites
4 Both (1) and (3)
Explanation:
Neurons are classified on the basis of dendrites attached to it. Based on the number of axon and dendrites, the neurons are divided into three types, i.e.,multipolar(with one axon and two or more dendrites; found in the cerebral cortex), bipolar (with one axon and one dendrite, found in the retina of eye) and unipolar (cell body with one axon only; found usually in the embryonic stage).

Schwann cell is absent in
1 Myelinated neuron
2 Non myelinated
3 Astrocytes
4 Both (2) and (3)
Explanation:
Astrocytes do not have schwann cell, they are glial cells and help in maintaining blood brain barrier.

Unmyelinated nerve fibres are commonly found in
1 ANS
2 Somatic neural system
3 Both (1) and (2)
4 None of these
Explanation:
Unmyelinated nerve fibre is enclosed by a Schwann cell that does not form a myelin sheath around the axon, and is commonly found in autonomous and the somatic neural systems.
