Transport in Plants

 In a simple plant like an alga, materials enter or leave the cells in its body by diffusion. within the fell itself, materials are distributed by the circular streaming movement of the cytoplasm. In higher land plants, special conducting tissues, known as vascular tissues, carry out transport. These vascular plants include all flowering plants and non flowering plants such as ferns and gymnosperms. Many of these plants also have an additional system of rated tubes to assist in transport.
