Parasite | Saprotroph |
They depend upon other organisms for their nutrition. | They feed on dead and decaying matters and obtain nutrition from them. |
Their hosts are alive. | Their hosts are dead. |
They may cause harm to the host. | They cannot cause any harm as the host is already dead. |
E.g. Cuscuta, lice | E.g. Fungi |
Xerophytes | Hydrophytes |
These plants grow in hot, dry areas like deserts. | These plants grow in water. |
The leaves are modified into spines to reduce water loss. | Leaves are broad and large. |
Stomata remain sunken inside the epidermis to reduce water loss. | Stomata are only present on the upper surface of the leaves. |
Root system is well developed. | Root system is not that well developed. |
Air sacs are absent. | Air sacs are present inside the stems to keep the stems erect in the water. |
E.g. cactus | E.g. Hydrilla, lotus. |
Algae | Fungi |
Cell wall is made up of cellulose. | Cell wall is made up of chitin. |
Cells contain chloroplasts. | Cells do not contain chloroplast. |
They can prepare their own food. | They obtain their food from dead organisms. |
They may be green, brown or red. | They are mostly colourless. |
