The given problem is talking about these types of placentations found in flooding plants.
00:06
So what is presentation? pleasantation represents the arrangement of the ovule in the ovary.
00:19
Now there are five types of placentation that are found in the flowering plants.
00:23
The first is their marginal placentation.
00:29
So the marginal placentation, in the marginal presentation, the placenta forms a ridge along the ventral suture of the ovary.
00:37
And the ovules are born on this ridge for me two rows so there are two rows like this when the ovules develop on these two trees now the example of a flower with marginal placentation is meaning p plant the second type of placentation is perital placentation so this is the sparrital presentation in parietal placentation the ovules develop on the inner wall of the ovary or on the peripheral part in this type of placentation ovary is one chambered but it becomes two chamber due to the formation of fall septum so this type of placentation is seen in mustard and arduan the third type of placentation is exiled placentation so the exiled placentation, in this type of placentation, the placenta is axial and the ovules are attached to it in multilocular ovary.
01:57
This type of placentation is seen in china rose and it's also seen in lemon and tomato plants.
02:12
The fourth type here is basal placentation...
