Hi your answer please follow me
Explanation:
There are various organs in an organism. These organs must be carefully controlled and coordinated for the survival of an organisms. In the body of an organism various fluids are secreted from the glands of the endocrine system. These hormones are responsible for the overall growth and development of an organism.
Answer:
Multicellular organisms such as humans have complex organs and organ systems. Furthermore, most multicellular organisms are composed of at least a few billion cells. Hence, it is important to have control and coordination among the cells.
In humans, processes pertaining to control and coordination are undertaken by the nervous system and the endocrine system. In plants, the same role is exhibited through various plant hormones such as auxins, gibberellins, and cytokinins.
In unicellular organisms, complex systems of control and coordination were thought to be non-existent. However, recent findings have confirmed that unicellular organisms such as bacteria do indeed interact with other bacteria through a cell-to-cell signalling process called quorum sensing.
