The closest living relative of P. chromatophora is the heterotroph, P. ovalis. P. ovalis uses threadlike pseudopods to capture its prey, which it digests internally. Which of the following, if observed, would be the best reason for relabeling P. chromatophora as a mixotroph? // as a mixotroph instead of an autotroph?
A) a threadlike pseudopod
B) a pigmented central vacuole, surrounded by a tonoplast
C) a vacuole with food inside
D) a secretory vesicle
E) a contractile vacuole

Option-(C): A vacuole with food inside.

Explanation:

The plant cells consists of the different organelles which are required to maintain the optimum level of food productivity to drive the different processes inside the environment and maintains the balance for the conservation of energy inside the environment or any space. As, the vacuoles are there either to store food resources or has the capacity to store the required amount of enzymes for the sake of digestion of food materials and other substance which enters the plant cell, while the enzymes are there to digest the macro-molecules into the basic components.
