1. Because the chloroplasts that actually photosynthesize are found in the tops of the onions - the part that is actually above ground. There's no reason for there to be chlorophyll in the onion skin itself because these grow underground
No chloroplasts in cheek and onion cells
You can't see chloroplasts in an onion skin cell since the onion was underground. When the onion is underground, the sun can't reach the onion so the onion skin cells can't make glucose. The onion does have chloroplasts in its cells at the top of the onion. That's where he sunlight can reach the onion.
There are no chloroplasts in bulb.Thats because they do not get sunlight.
Onions are the root bulbs of onion plants. The plant itself contains chloroplasts, which cause the green colour, whereas the onion bulb itself contains other pigments and few, if any, chloroplasts.
Onion cells do not have chloroplasts because the onion is underground where there is no light. Without light chloroplasts have no purpose, so onion cells just don't have them.

The bulb of the onion does not but the leaves of the onion plant do.

No. Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form.
Two organelles not visible in an onion cell are the centrioles and lysosomes. Centrioles are involved in cell division and are not present in plant cells like onion cells. Lysosomes are membrane-bound organelles that contain digestive enzymes and are more commonly found in animal cells.
Chloroplasts
No, you cannot observe chloroplasts in onion cells because onion cells do not contain chloroplasts. Onions belong to a group of plants known as monocots, which typically lack chloroplasts in their cells. Chloroplasts are mostly found in the cells of green plants that undergo photosynthesis.
Chloroplasts can be seen in Elodea leaf cells but not in the epidermal cells of onion cells. Chloroplasts are responsible for photosynthesis in plant cells, containing chlorophyll that captures sunlight for energy production. Onion epidermal cells do not contain chloroplasts as they do not perform photosynthesis.
