Hi, as for the question, we have to describe any three ways through which plants protect themselves from being eaten by herbivores.
00:08
Once herbivores find and assess a plant, structural defenses can discourage consumption.
00:15
These structures include spines, scycombs, thick leaves and microscopic sand and needle -like particles inside the plant tissue.
01:12
These are the structures with the plant defends themselves from the herbivores.
01:18
So we have to explain three.
01:19
So the first one which is we are going to see in detail is spine sense.
01:36
It is the evolutionary modification of stems as thorns and leaves as spines.
01:57
These sharp pointed extension can deter large herbivores but generally less effective against the smaller, more maneuverable herbivores like insects.
02:22
The second structure is trichomes.
02:33
To guard against the herbivores insects, some plants use a layer of plant heads...
