Given below is a set of five terms:
Active immunity, antigen, antibody, bacteria, lymphocytes (defense mechanism of the body)
Rewrite the terms in logical sequence as directed at the end of the statement.

An example has been done for you:
Example: cortical cells, root hair, xylem, soil water, endodermis (absorption of water by the plants)
Answer: soil water, root hair, cortical cells, endodermis, xylem.

Solution

Active immunity refers to immunity due to the immune system’s response to a microorganism or a vaccine. The presence of bacteria in the body is recognized by antigen (the protein part of bacteria) which in turn activates the B lymphocytes to produce the antigen-specific antibodies through clonal expansion and thereby initiating the immune response. So, the correct sequence is active immunity, bacteria, antigen, lymphocytes, antibody".

Absorption of minerals by the epidermal cells of root and root hair causes the water to enter from surrounding soil into roots. It further reaches the root xylem. Thus, due to a continuous uptake of water by root cells, a water pressure is created in the root xylem. This pressure is called as________
