So if we see the anatomy of a dichot root, then we'll see the following structures in it.
00:15
So this is the diagram of ts of a dichot root, that is the transverse section of a dichot root.
00:23
So firstly, the first layer that is present in the dichot root, the outermost layer is the pyliferous layer, also known as the epiophores layer, also known as the epioreous.
00:32
Dermis or the epidermal layer.
00:36
Now from the epidermis rises the root hair which is responsible for increasing the surface area for absorption of mineral nutrients and water by the roots.
00:47
Then it is followed by an entire layer of cortical cells which is known as the cortex.
00:54
So cortex have cells which are loosely bound to each other.
00:59
That is there are intracellular spaces between the cells of the cortex.
01:04
Then it is followed by a layer of endodermis.
01:08
So endodermis is this layer which is surrounding the vascular bundle and this this and this layer is and this layer has which are tightly packed with each other without any intracellular spaces.
01:26
Then the endodermis is followed by a layer of casparian strip.
01:33
Then there is the floam and the protozylum and the metazilum which formed the vascular bundles of the roots.
01:44
So, floam is responsible for conduction of food material produced in the leaves to the rest of the body and xylem is responsible for transport of water and mineral nutrients from the root to the other parts of the body.
01:58
Then there is a layer of peri cycle which is in between the xylem and the floyum.
02:05
So this is the layer of pericycle.
02:08
And then there are certain passage cells in the endodermis.
02:13
So the endodermis cell has certain passage cells present in them in between the cells which are tightly packed.
02:22
So this is the basic anatomy of a dicot root...
