1. The cells of an onion skin are generally rectangular in shape and range in size from 0.25 to 0.4 millimeters in length (250-400 micrometers). A millimeter is abbreviated by mm and a micrometer by the Greek letter mu (12th letter of Greek alphabet) followed by an m:
millimeter
about 1/25th of an inch
micrometer
1/25,000th of an inch
Left: Microscopic view of an onion skin showing several rectangular cells, each with a small, spherical nucleus (red arrow). The slide was stained with a drop of yellowish-brown gram's iodine. Right: Highly magnified view of a cell from the meristematic root tip of an onion showing enlarged nucleus containing 16 chromosomes. The cell is in prophase of mitosis, with distinct chromosomes (chromosome doublets) and a disintegrating nuclear membrane.

What does an onion cell look like after adding a salt solution NaCl?
This depends on the nature of the NaCl solution...If it is a Hyper-tonic solution (More concentrated solution than onion cells), water will move by osmosis down it's concentration gradient, from a region of less negative water potential (high Ψ) in the onion cell, to a region of more negative water potential (low Ψ) in the solution through a selectively/partially permeable membrane;so the onion cell will be plasmolysed and will look "flaccid" (vacuole gets smaller and shrinks).The vice versa happens with a Hypo-tonic (less concentrated solution than onion cell) NaCl solution;The onion cell will then look "turgid" (has a large vacuole exerting a pressure on the cytoplasm and pushing it towards the cell's cellwall to make it "tensed".
