Chloroplasts are necessary for photosynthesis. This must in some way be necessary to operate the opening and closing of stoma. The neighboring epidermal cells do not have chloroplasts and do not require large amounts of energy from photosynthesis do to their simple job of being the "skin" of the leaf. These epidermal cells are fed by lower layers which do have chloroplasts.
The presence of chloroplasts in the guard cells mean photosynthesis will occur. This leads to an accumulation of glucose in daylight and the guard cells will absorb water by osmosis from the epidermal cells which lack chloroplasts and do not produce glucoes. The guard cells becomes turgid and so the stoma opens to allow water loss.
Guard cells are photosynthetic because they enjoy sexual pleasure from the chloroplasts. Chloroplasts have a good time rubbing up against guard cells. Yes. =]
The upper and lower epidermal cell do not have chloroplasts, thus photosynthesis does not occur there.
Due to the presence of chloroplasts in the gaurd cells these are green in color.
because it is made up of closely bound paranchyma cell.
Guard cells contain specialized organelles called chloroplasts, which are responsible for photosynthesis. These chloroplasts enable guard cells to produce sugars and other molecules needed for energy. The surrounding epidermal cells, on the other hand, do not typically contain chloroplasts as they are not directly involved in photosynthesis.
Lower epidermal cells
okay, animal cells don't have chloroplasts!! only plant cells do!! chloroplasts give the plant its green color!!
no

Onion bulb is not photosynthetic.So chloroplasts are absent.
Lower epidermal cells
Mesophyllic cells are the cells that lie between the lower and upper epidermal layers of leaves and contain chloroplasts necessary for the production of sugars from sunlight.
The epidermal cells of sponges are responsible for cell adhesion and maintenance of their shape and structure. The epidermis is composed of pinacocytes (epidermal cells) which are flattened cells in the sponge's body wall.
Langerhans cells
Chloroplasts, because the onion does not undergo photosynthesis. The onion plant does but the onion itself is a bulb.
Epidermal cells are supplied with nutrients from blood vessels in the
Epidermal cells receive nutrients and oxygen from the blood vessels in the dermis.

HIV mainly attacks cells in the immune system. I'm not aware of a major impact on skin (epidermal) cells.
