| Irritability: | Responds slowly to stimulus. | Responds faster to stimuli. |
| Specialized Organs: | Lack of specialized organs for excretion, respiration and coordination. | Possesses specific organs for excretion, respiration and coordination. |
| Cells: | – Presence of cellulose. – Cell wall vacuoles are present and usually large. – Centrioles absent. | – Absence of cell cellulose. – Cell wall Vacuoles are usually absent, when present, are usually small in size. – Centrioles are present. |
| Shape: | Have no fixed number of parts. They usually have branches. | They are usually compact with a fixed number of parts. |
