What aparatus do i need to test is a potato tuber cell conains chloroplasts

Potato tuber cells do not contain chloroplasts as they are grown inside the soil so no sunlight is required so no chloroplasts.

Explanation:

Instead of chloroplasts potato tubers consists of amyloplasts. In all plant cells, plastids are always there. They are required as it is the place where amino acids and fatty acids are made. Amyloplasts are the place of starch synthesis in non-green plants.

If you place the potato tuber in sunlight the amyloplast may get converted to chloroplasts.

A hand-held SPAD-502 plus chlorophyll meter device is to check the chloroplasts.
