Golgi apparatus, chromatin, lysosome, flagellum, nucleus, vesicle, central vacuole.
need help asap please.
A positive confirmation of an animal cell, under a microscope, can be done by identifying the organelle that are present (almost) exclusively in either animal cells or plant cells. Of the given list, only lysosomes and central vacuole fulfill this criteria. Lysosomes are present in animal cells and can be found in the cytoplasm. Central vacuole, on the other hand, is present in plant cells. Animal cells may contain one or a number of smaller vacuoles. Other organelles, listed here, such as nucleus, flagellum, chromatin, golgi apparatus, etc. are present in both animal and plant cells.
To be able to observe these organelle, one would need a very high resolution microscope (probably an electron microscope). Plastids and chloroplasts are two other organelle that are exclusive to plant cells and can help in positively identifying a cell.
Hope this helps.
