I have observed a piece of leaf(pink in colour) under the microscope, the following is what I have see:
The colour of palisade mesophyll cell is like this:
And the "unknown" cells in the red square is about this
What I want to ask is :
1) What's the structure in the red square?
2) Is the area between palisade mesophyll cells and "unknown" cells contains air, water or anything else?
(Sorry for ugly drawing.)
THX a lot !~
Actually, the sample I used is picked from a plant in the little flower bed at roadside.
So, I don't really know what species it is.
The leaf is acicular, similar to ones of cactus (about the shape of this : " ɭ ") , but it is much softer.
And, actually, I am quite sure that all of them are cells, because I see the nucleus and vacuole in each of them. And I didn't stain it, it just added water to moisten it.
In your microphotograph, I see there is a longitudinal section of vascular bundle.
So, I GUESS, would the bulk of cells in the red square be the vascular bundle?
If yes, is it possible that waht I saw from the microscope is the transverse section of the vascular bundle, so that the shape of that bulk of cell I saw is much more regular than the microphotograph in your answer?
And, thx for your commend. =]

It appears to me that the packed cells at the bottom half of the red square is a stoma, where air can get in and out of the leaf. It may be a space behind the stoma, that's the upper part of the red square.
I wonder if the pink colour was the original pigment of the leave or if it was a stain. Please tell me the species name where that leaf comes from.
If it is stained red/pink, then it may not be a cell at all. It may be a space but the water(or paraffin for mounting) got faintly stained. See if this is helpful to you.

the reddish colour parts sometimes gets across and out of the cell walls. I will take them as artifacts.

btw, that's a very good drawing of yours considering you draw it on a computer. cheers!
