The organismal theory teaches that _____.
natita [175]

Answer:

A. the basic unit of life is the organism

Explanation:

According to the organismal theory, organisms are the basic unit of life. The organismal theory contradicts the cell theory of life. The organismal theory states that some of the organisms do not have distinct cells. For example, fungi.

Since the cells in the multicellular organisms are interconnected by one or other means, organisms are the structural unit of life; not the cells.

The organismal theory states that irrespective of the level of body organization present in an organism, all the components such as cells, tissues, organs, etc. work together to facilitate growth and development of whole organisms.
