Definition
Do not have true roots, stems and leaves.
These plants have organs that appear similar to true roots, stems and leaves but they are not true organs. Because of the lack of roots and stems these plants cannot reach water under the soil and actively take it up. They absorb water directly through their cell walls and the water moves from cell to cell via osmosis. |
|
|
Term
| Vascular tissue consists of special cells for the transport of water and nutrients. The root-like, stem-like and leaf-like organs that appear on these plants are not considered true because they do not contain vascular tissue. Lack of vascular tissue limits the size of the plant because it cannot transport water and food very far against gravity. |

Term
Have structures called true roots, stems and leaves.
ii) Vascular tissue is present.
These special transport cells run continuously through the roots, stems and the leaves.
iii) Larger in size.
iv) Cuticle is present to reduce water evaporation from leaves.
Examples: Ferns, conifers, flowering plants |
