Please see the attached image for the reference. I have been seeing these cells in the Arabidopsis thaliana seed (post germination) whenever I go for microscopy. The cells are attached to seed coat and they are alive for more than a week.
I did a google search using image and got no relevant results.
I am very curious what are these cells and I will be thankful if could suggest me what is the term used for these cells or any other relevant information.
