what is the difference between slime mould and protozoans

Slime mouldsare the saprophytic protists.

• They move along decaying twigs and leaves

• Under suitable conditions, they form an aggregation called plasmodium, which grows and spreads

• Under unfavourable conditions, plasmodia differentiate to form fruiting bodies bearing spores at their tips

• Spores possess extremely resistant true walls, which make them capable for surviving for a long time under adverse conditions

• Spores disperse by air currents.

• All Protozoans are heterotrphic.
• They live as predators or parasites.
• Protozoans are believed to be primitive relatives of animals
• They are small, microscopic, unicellular and colourless organisms with varied forms, shapes and symmetry.
• They move with the help of Pseudopodia, flagella or cilia.
• Some fresh water forms get rid of excess water through contractile vacuoles.
• Asexual Reproduction - Binary fission, multiple fission or budding.
• Sexual Reproduction - Syngamy or Conjugation.
• Includes Phyla - Zooflagellata, Sarcodina, Sporozoa and Ciliata
