The condensed structures that are chromosomes first become visible during C. Prophase, the first phase of mitosis.
Answer:
Tissue
Explanation:
Multicellular organisms are complex and every complex organism consist of building blocks. This is the case in the level of organization in living organisms. All living organisms are made up of CELLS. In multicellular organisms i.e. more than one, the cells that perform a similar role come together to form the TISSUE.
Tissues with similar function together forms the ORGAN. Organs that perform similar functions collectively makes up ORGAN SYSTEM. Based on this, the level of organization moves from the least complex "cells" to most complex "organ systems".
The order is as follows:
Cell-----> Tissue-----> Organ-----> Organ systems
