- <em>Neurons</em> are the cells of the nervous system that transmit and receive nerve impulses.
- The basic structure of a neuron consists of the <em>cell body, the axon, and the dendrites. </em>
- The<em> cell body</em> consists of the nucleus and thus contains the genetic material of the neurons. Emerging out from this are 2 types of extensions - dendrites and axon.
- The <em>dendrites</em> are involved in receiving messages from the other neurons whereas the <em>axon</em> is responsible for conducting the electrical impulses away from the cell body.

Plants manufacture glucose during photosynthesis. Which would be the process that plans use to make food using sunlight.
chemicals that are secreted from antigen-presenting cells then activate helper T cells describes the role of cell-to-cell communication during a response to an invasion of antigens.
Explanation: Antibodies are present on the surface of the cells, and binds specifically to antigens and can also engulf pathogen and process these cells presenting them to MHC class 2. This complex is activated by helper T cells to secrete antibodies and macrophages. This interaction of B-cell and MHC class 2 complex with helper T cell is cell-mediated immune response.
