What is the difference between cells in onion peels and cells in spinach?

Hint:Plant cells are eukaryotic cells which are mostly present in green plants. They have very different features including primary cell walls containing cellulose, hemicelluloses and pectin also plastids are present. The plastids help in photosynthesis and store starch, vacuole that maintains turgor pressure.

Complete answer:
Onion peel cells:- These cells do not have chloroplast and photosynthesis processes do not take place in the onion cell. The peel of onion acquired from modified leaves which perform the function of storage. In the onion peel storage organelles are leucoplasts. The cells are uniform in structure and formed by many layers.
Spinach cells:- The cells of spinach leaf have the green coloring pigment called chlorophyll contained in chloroplast. The cells carry the process of photosynthesis and store their food in the form of starch granules. The cells of spinach leaf are not uniform in structure as seen in onion peel while they all are of different shapes and sizes found in layers from the dorsal to the ventral side.



Note:In the spinach leaf photosynthesis takes place it means they can manufacture their food and chloroplast help to store the food while on the other hand onion cells cannot manufacture their food.
