In the given question, we are being asked about discussing the internal structure of dorsi -ventral leaves with the help of a label diagram.
00:09
So this on the screen you see a label diagram of the internal structure of a dorsi -ventral leaf.
00:16
Now dorsi -ventral leaves, these types of leaves are found in dicot plants.
00:22
So the important anatomical features of dorsi -ventral leaves are, include an upper epidermis.
00:33
There is an upper epidermis or the adaxial epidermis which is the outermost single layer made of parent chymeter's cells the epidermal cells sometimes have outgrowths called papilla and the epidermal cells these are devoid of any chloroplast and stoma are also absent in the upper epidermis so there is no stomata in this layer now there is a lower epidermis or the abasial epidermis so it is similar to the upper epidermis just the difference is that it contains tomato however chloroplasts are absent in lower epidermis also accepts the gar cells of the stomata now we have mesophyll so mesophyll it lies in between upper and lower epidermis and it can be divided into two regions that is palisade mesophil and spongy mesophil.
01:50
So while you said mesophil, these are contains elongated columnar cells without any intercellular spaces as we can see in the given diagram.
01:59
So these cells contain chloroplasts, so they have chloroplasts...
