Answer: option C - A heterotrophic cell
Explanation:
An organism is said to be an heterotroph if it is unable to produce its own food, making it rely on green plants or other autotrophs for nutrients. So, heterotrophic organisms are usually the classed as consumers (primary, secondary etc).
Due to the need of energy consumption and absorption, heterotrophic organisms (with heterotrophic cells) usually have high mitochondrial content (to help in energy metabolism) and moves about (mobile) in search of nutrients (prey)
