Answer:
Chloroplasts
Step-by-step explanation:
A cell is most likely to be a plant cell if it contains chloroplasts. Chloroplasts are organelles that are responsible for photosynthesis, and contain a green pigment called chlorophyll, which gives plants their characteristic color. Chloroplasts are found only in plant cells and some algae, but not in animal cells or fungi. Chloroplasts are one of the distinctive features of plant cells, along with the cell wall and the large vacuole.
