Abstract

The term “plant” implies the possession of multi cellular traits, whosecell walls contain cellulose and which have the ability to carry outphotosynthesis. Green plants provide a substantial amount of world‟smolecular oxygen.[1] Plant cells are characterised by their large waterfilledvacuole, chloroplasts and rigid cell walls made up of cellulose,hemicelluloses and pectin. Cell division includes the development of aphragmoplast used for the construction of the cell plate in the laterstages of cytokinesis. Like in animal cells, plants cells alsodifferentiate and develop into multiple cell types. Meristematic cellsthat are totipotent can differentiate into protective, vascular, storage orreproductive tissues.[2] Specialized structures called xylem and phloemare used in the transport of nutrients between different parts of theplants. They also have roots for taking up water and minerals. The xylem is involved with thetransport of water and minerals to the rest of the plant from the roots and the phloem isinvolved with the transport of sugars from the leaves to the roots.[2]
