Question

dendrom, nissl's granuale, axon, axon ending, collenchyma which one is odd​

Answer 1

Answer:

axon is good,,I told u answer that means follow me and I follow u back immediately

Answer 2

ANSWER:

The odd one is collenchyma.

REASON:

• Collenchyma is a plant tissue.

• Dendron, nissles granules, axon, axon ending are the part of neuron in animal tissue.

Explanation:

COLLENCHYMA:

• It is a living simple tissue of a plant.

• It gives mechanical support to the petiole of young leaves .

• It is associated with chloroplast and therefore performs photosynthesis.

• Collenchyma forms the hypodermis of dicot stem.

• They have thickening at the corners of the cells.

NEURON:

• It is also called neural tissue.

• These are absent in plants.

• A neuron has the following parts : dendrites or dendrons , cyton or cell body , axon.

• Dendrites are branches arising from cyton . They conduct the impulses towards the cyton.

• Cyton consists of cytoplasm , nucleus and nissles granules.

• Nissiles granules are nothing but the endoplasmic reticulum associated with ribosomes. They are the site of protein synthesis.

• Cyton has a long thread like filament called axon. Axon has cytoplasm called axoplasm.

• Axon is surrounded by neurilemma. In PNS myelin sheath is formed by Schwann cells.

• Axon conducts the impulses away from cyton. Axon terminates in few branches called axon terminals.

• Axon terminals have synaptic knobs associated with them. These synaptic knobs contain neurotransmitters like acetylcholine.
