Answer:
The external coverings of diatoms are made up <u>silica </u>, while slime molds have cell walls containing <u>cellulose.</u> Diatoms are <u>photoautotrophs</u> because they make food through photosynthesis, while slime molds are <u>heterotrophs</u>.
Explanation:
Diatoms can be described as algae that are mostly single-celled. They are made up of a unique kind of cell wall composed of silica. This cell wall is termed as a frustule. Mostly, diatoms are capable of carrying out photosynthesis and hence make their own food.
Slime moulds can be described as organisms that are fungus-like protists. They are not capable of producing their own food and feed on other plants. Hence, they are heterotrophs.
