All right, so two of the three ground tissues, types of ground tissue are the colinchema and sclerinchema, and we will compare them.
00:12
So one thing to note is that they both have a thick cell wall.
00:26
Okay, but what differentiates them is that the sclerenchyma has also a secondary cell wall, and this secondary cell wall is dead.
00:45
Okay, so normally the cell wall is kind of thin and can stretch and move, and so the cells might be actively growing, but in this case, the cells do not grow.
01:01
So if you think of, like, the coating on the outside of a seed, right? that doesn't need to stretch or grow.
01:08
That just needs to sort of exist in its way...
