Question
Differentiate between dendrites and axons.

Answer

Dendrites and axons:
  Dendrites   Axons
1. Dendrite is a small projection arising from the neuron. It conducts the nerve impulse toward the cell body. 1. Axon is a single, long projection that conducts the nerve impulse away from cell body to the next neuron.
2. Nissl’s granules are present in dendrites. 2. Nissl’s granules are absent from axons.
3. Dendrites are always non-myelinated. 3. Axons can be myelinated or non-myelinated.

Kritika's biology teacher explained the different phases of plant growth in her class. She taught that growth of plants takes place in three successive steps or phases from germination to maturation phase. Kritika reached home and asked her elder sister, a biology post-graduate student to clarify the phases in detail. Kritika's sister told her that she will explain the complete process with the help of experimentation. She took few seeds of pea and germinated them on a circular filter paper, soaked with water in a petri-dish. After two days of growth, she picked up a couple of seedlings with straight radicle and marked it from tip to base with the help of a waterproof ink and again placed the seedlings on moist filter paper to allow them to grow.
