I don't know, except for the fact that they wouldn't taste very good in a salad. Why don't you look this up on a scientific website instead of pining for answers on Ask.com? That's pathetic.
the cell membrane is like a guard because it only allows chemicals in and out of the cell
A guard cell is a type of cell found in the epidermis of plant leaves. It is not a tissue or an organ; rather, it is a specialized cell responsible for regulating the opening and closing of stomata to control gas exchange and water loss in plants.
Ribosomes look like granes of sand
Both play part in allowing gases in and out, esp carbon dioxide which is needed for photosynthesis. Stoma, by being a pore; Guard cell, by opening (becoming turgid) and closing (become flaccid) when necessary. They are also both necessary for the leaf's survival.
the DNA
The guard cell of stomata look like a balloon when it is turgid. Two such cells form the pore of the stomata. When both guard cells of a stomata are deflated by exo-osmosis the stomatal pore is closed.
they look like seeds

It is a green looking cell.
It looks like a cell that is pineapple coloured
A White Blood Cell looks like Sperm!
guard cell and palliside cell
A guard cell is a type of cell found in the epidermis of plant leaves. It is not a tissue or an organ; rather, it is a specialized cell responsible for regulating the opening and closing of stomata to control gas exchange and water loss in plants.

A semi-permeable membrane. It could be compared to dialysis tubing.
A bee guard for a hummingbird feeder looks like a trough of water. The trough looks like a circle around the top of the feeder.
depends on what the organism is that your trying to look at
