Skin and hair are two types of cells that can be seen from outside. Several types of eye cells can also be seen:
* sclera (white of the eye)
* pupil (black circle inside iris)
* iris (colorful ring around pupil which controls focus)
* cornea (clear part in front of iris and pupil)

A "multi cellular" organism has a body made out of more than one cell. Humans are multi cellular organisms. A "unicellular" organism has a body body made out of just one cell. An amoeba is a unicellular organism.
If a plant cell is flaccid, water has escaped from inside the cell to the outside, by osmosis. Under a microscope, the cell membrane can be seen to detach itself from the cell wall.
An example of cellular organization is seen in the human body, where cells are organized into tissues, tissues are organized into organs, and organs are organized into organ systems that work together to maintain homeostasis and carry out specific functions.
The female egg.
The largest cell in the human body is the ovum cell. The ovum cell is approximately one millimeter in length and is the only cell that can be seen without a microscope.

No, endoskeletons are on the inside like human skeletons are. Endo is a latin prefix meaning "in". Exo means "out" therefore exoskeletons are on the outside as seen in beetles and other insects.

A cell is like a brick because the brick is part of the brick wall that covers your body and can be seen through out yourself. Cells are like a brick wall because a brick wall is a cluster of these many bricks that build up to become the human body.

A human cell is normally 0.1 mm in the size. Human cells cannot be seen by the naked eyes without the help of magnification.
The smallest size of a cell that can be seen with the unaided human eye is about 100 microns, which is roughly the size of a grain of sand. Anything smaller than that would generally require a microscope to be visible.
