Answers;
-Frustule
-Autotrophic
-Heterotrophic
The external coverings of diatoms are made up of frustule , while slime molds have cell walls containing cellulose . Diatoms are autotrophic because they make food through photosynthesis, while slime molds are heterotrophic because they eat decaying plant matter.
Explanation;
- Diatoms are tiny single-celled algae that are covered with glass like shells made of silica. Slime molds on the other hand are fungus-like protists that re heterotrophic like protozoa in the kingdom protista.
- Diatoms are food producer or autotrophs while the slime are consumers or heterotrophs and depend on the product produced by the primary producer such as plants, diatoms etc.
- Diatom can carry out photosynthesis while the slime mold can not carry out the process of photosynthesis but are decomposers.
- Slime molds are fungus like protists and have both plant and animal like characteristics while diatoms have only plant like characteristics.
