Hello students, so a question is what is tissue and question is asking for the role of tissue in the growth of plant.
00:12
So tissue is actually group of cells and these group of cells have similar structure and these cells act together to perform a specific function.
00:50
Okay.
00:52
So suppose we have this single cell.
00:55
This is cell.
00:56
In this cell, it's have its own nucleus, it's mitochondria, er.
01:04
Okay, these all things are present in this cell.
01:06
But when these kind of cell are grouped together like this, and these cells are similar in the structure and also they perform the similar function.
01:21
This group of cells is basically called as tissue.
01:32
Okay.
01:33
So these cells are actually, this tissue is actually performed for unique purposes.
01:49
And when these group of tissue, when these group of tissue combined, these group of tissue actually form the organs.
02:15
If we are talking about plant organs, then these organs such as leaves, flowers, roots, these are organs.
02:30
Okay.
02:31
So the question is also asking the role of tissue in growth of plant.
02:40
So role of tissue in growth of plant.
02:54
So different kinds of tissue have different kinds of role.
02:57
Okay.
02:58
So when we are talking about plant tissue.
03:06
These plant tissue can be of different types.
03:11
The first type is meristmatic tissue.
03:28
This maristmatic tissue is actually having the immature cells.
03:37
And these immature cells are actually capable of division.
03:47
Okay, this is the first kind of tissue.
03:50
When we are talking about maristmatic tissue, then it can be apical meristmatic or we can say apical meristam.
04:02
Which is present on the growing tips and second one is intercalary merestam and third one is lateral merestam so these all three are actually play role in the growth of the plant okay so when we are talking about the second tissue the second tissue is actually the permanent tissue okay so this permanent tissue is actually having the mature cells and these mature cells are incapable of division.
05:12
So, this permanent tissue can be simple...
