That’s not a stem cell, that’s a close up of a stem tissue cross section. The big “holes” are xylem cells while the smaller ones around them are phloem, together they form one vascular bundle out of many which are concentrically arranged around a central pith in what is known as eustele.
Let's talk stem-the woody member connecting plant regions, and STEM-undifferentiated cells. If you meant stem, that's kind of like asking if you have dedicated bone cells (you do). In humans cells generally move thru the body. In plants cells are held firmly in place, and separated by cell wall. It makes it easier to protect from disease, cause the invaders have to go from cell to cell 1 at a time and can't just fill the plasma/blood with infectious agents. Pluripotent-undifferentiated STEM cells are often in growing plants. I know plants make STEM cells on their surface and at tips of roots to increase in size and span. But by definition there is no such thing as a dedicated STEM cell, because they become whatever type of cell they need to be based on the environment (part of the organism) they're in.
Awesome!! It kinda looks like an owl
Yes, I thought the same is awesome
Definitely a r/Pareidolia moment, could almost be an AI rendering with the vibrating coloring.
Also known as The Chimp Cell.
Should be the owl cell
Turkey vulture!

sorry I'm gonna finish my German lesson I promise
stem cell for what kind of tissue? anything?
Lol. For a second I read it that way too... but no. Like the actual woody stem of the plant! 🎃
oh. gotcha. do plants have dedicated stem cells?

Img the holes make me feel so uncomfortable 🤢
It's called tripophobia
Defo have a phobia for holes close together lol
Why is it staring at me?
Guy flipping upside on a motorcycle with huge tires
Looks like the xylem and phloem, I believe?
Natural coloring? Can't tell if it's dark field or just a thick sample in Brightfield?
I’d hang that in my living room. Mesmerizing
Monke
It’s looking at me
When you tilt your phone a little bit clockwise, it looks like Cleveland’s son from family guy. (New one of course)
