20245.	Question : Based on the figure given below which of the following statements is not correct ?
Answer» Movement of SOLVENT molecules will take place from chamber `A`to `B`. Movement of solute will take place from `A` to `B` Presence of a semi-permeableis a per- requisite for this process to occur. the direction and rate of osmosis DEPENDS on both the PRESSURE gradient and concentration gradient. Solution :Solution A and solution B are separated by a semi-permeable membrane. Solution A has higher water potential. THEREFORE, OSMOTIC movement of water molecules (solvent molecules) will occur from solution A to B solution particles cannot pass through semi-peemeable membrane.

20246.	Question : Based on processes, mention the types, location of neuron with examples.
Answer» Solution :Neurons are functional unit of neural system. In microscopic structure of neuron three main parts are observed : (1) Cell body (2) Dendrites (3) Axon. (1) Cell body : Body of neuron is CALLED cyton. Cyton may be oval, round or stellate shaped. Cytoplasm of neuron is called NEUROPLASM. Big round nucleus is present. In the centre of the cyton. Neuroplasm, consist of cellular organelles, small basophilic granules (Nissl.s granules) Nissl.s granules are mostly near the nucleus. (2) Dendrites : Divides, redivides and project out of the cyton. It also contains Nissl.s granules. Dendrites transmit impulses towards the cell body. (3) Axon : Is a long FIBRE, the distal end of it is branched. Each branch terminates into bulb like structure called Synaptic knob. Synaptic knob : It has synaptic vesicles containing chemicals called Neurotransmitter. The axon transmit nerve impulses away from the cyton to a synapse or to a NeuroMuscular Junction. Types of neurons : Based on the number of axon and dendrites, the neurons are divided into three types : (1) Multipolar : One axon and two or many dendrites. i.e. : cerebral cortex. (2) Bipolar : One axon and one dendrite e.g. : retina of eye. (3) Unipolar : Cell body with one axon only e.g. : present in embryonic stage. Two types of axons are present accordingly neuron is (i) Myelinated neuron (ii) Nonmyelinated neuron. (i) Medullated neuron : The myelinated nerve fibres are enveloped with Schwann cells which form a myelin sheath around the axon. The gaps between two adjacent myelin sheaths are called nodes of Ranvier Myelinated nerve fibres are found in cranial nerves and spinal nerves. (ii) Non-myelinated neuron : They are enveloped by a Schwann.s cells but myelin layer is not formed around the axon. It is found in SOMATIC neural system and AUTONOMOUS neural system.
