Collenchyma is the tissue of the primary body. The cells of the tissue contain protoplasm and are living without intercellular spaces. The cell wall articulate at the corners and are made up of cellulose, hemicellulose, and pectin.

Explanation:
A phase is a part of a system with uniform composition.
- In physics and chemistry , a phase in a physically distinctive form of matter , such as solid , liquid , gas or plasma.
- A phase matter is characterised by having relatively uniform chemical and physical properities . Phases are different from states of matter.
- The states of matter (e.g ., solid , liquid , gas ) are phases but matter can exist in different phases and yet be in the same type of matter. For example , liquid mixtures can exist in multiple phases such as oily and aqueous phase.
- some different types of phases are : solid, liquid,gas , plasma etc.
- The term phase can also sometime mean describe equilibrium in phase diagram
