Answer:
Chloroplasts in the cytoplasm of the cell
Step-by-step explanation:
The options you were given are the following:
- nucleus is located inside of the cell
- numerous cilia on the outside of the cell
- chloroplasts in the cytoplasm of the cell
- a thin membrane around the edge of the cell
The organelles that would indicate that the observed cell belongs to a plant rather than an animal are chloroplasts. Chloroplasts are organelles that conduct photosynthesis - a process in which plants (and some other organisms that possess chloroplasts) get food. In this process, with the help of sunlight, plants transform carbon dioxide, water, and minerals into oxygen, which is released into the atmosphere, and glucose, which they feed on.
Both animal and plant cells have a cell membrane and the nucleus located inside of them.
The cilia are usually found in animal cells.
This is why the third option is the correct one.
