Question

Write the diagnostic characters of
( i ) Slime moulds
( ii ) zooflagellates
( iii ) Sarcodine.

Answer 1

Hint: Diagnostic characters of the characters due to which one organism can be different from others.

Complete answer: Diagnostic characters of slime mould :
1. They do not have chlorophyll.
2. They are surrounded by plasma membrane only however the spores are surrounded by cellulosic cell walls.
3. They live usually among decaying vegetation. They exhibit a wide range of coloration.
4. They have phagotrophic or saprotrophic nutrition.

The diagnostic character of zooflagellates :
1. The posses flagella for locomotion. The maybe free-living, aquatic, or parasites.
2. The body is covered by a firm pellicle.
3. They are generally uninucleate occasionally multinucleate.
Nutrition is holozoic and parasitic. There are also commensals.

The Diagnostic features of Sarcodine :
1. They develop pseudopodia which are a temporary protoplasmic outgrowth.
2. Pseudopodia are used for locomotion in engulfing food.
3. They are mostly free living.
4. Nutrition is commonly holozoic.
5. They are generally uninucleate.

Note: All single-celled eukaryotic organisms are Protista .
1. Members of Protista are primarily aquatic.
2. They have a well-defined nucleus in other membrane-bound organelles.
3. Protista reproduces sexually and asexually by a process involving cell fusion and zygote formation while some have flagella and Cilia for locomotion.
