transport system

A.

Materials are transported to and from individual cells in organisms. There are various mechanisms through which this transportation occurs, some of which include osmosis, active transport, mass flow, cytoplasmic streaming, and endocytosis. However transport within flowering plants is of nutrients (carbon dioxide, water and essential ions) oxygen, and other elaborated foods. Water and Ions are transported in the xylem vessels, carbon dioxide and oxygen diffuse in to the system and elaborated foods such as sugar and amino acids are transported by the phloem tissues.

In flowering plants water travels through distinct routes. These routes are discussed below:

Apoplast

This pathway consists of spaces within the cellulose cell walls. The volume of these free spaces is known as free space. It includes the water filled spaces of dead cells, hollow tubes of the xylem vessels and intermolecular spaces in the cell walls. This pathway avoids contents of the living cell and as such...
