Which of the following plant cell parts is not found in onion cells?

$\Large\green{\checkmark}$A. Chloroplast

C. Vacoule

B. Cell wall

D. Mitochondrion

${ \underline{ \blue {\sf{Reason}}}}$

The clear epidermal cells exist in a single layer and do not contain chloroplasts, because the onion fruiting body (bulb) is used for storing energy, not photosynthesis. Each cell has a cell wall, cell membrane, cytoplasm, nucleus and a large vacuole. The nucleus is present at the periphery of the cytoplasm. The vacuole is prominent and present at the centre of the cell, surrounded by cytoplasm.

Answer 2

The plant cell part which is not found in onion cells is Chloroplast (option A).

• A modified-stem system is exemplified by the onion plant.
• The onion plant grows underground and isn't exposed to sunlight, so it can't use photosynthesis to make its nourishment.
• The onion plant does not require chloroplasts because it does not prepare food.
• The onion plant has a bulb-shaped modified stem that stores and reserves nourishment.
• Onion cells contain vacuole, mitochondria, and cell walls, but chloroplast is absent because it does not prepare food.
