Plant Transport System

Plant Transport System. By: Kareem Ahmed. Plant Transport System. The plant transport system uses many different thin tubes inside it that carry liquids up and down the stem and all around the plant. The two main systems that are used are xylem and phloem.

Plant tissues

Plant tissues. How do we recognise them?. Where could this possibly come from?. Meristematic tissue. Meristematic tissue is composed of immature cells that grow, divide & differentiate giving rise to the other types of plant tissues. Eg. The root tip of an onion.
