I have just started studying about morphology of angiosperms. I'm learning about roots right now and I came across the following.
In monocots, adventitious roots are a characteristic feature whereas in dicots true roots are a characteristic feature. When I was younger, I had learnt that fibrous roots are a characteristic feature of monocots.
So I studied further to find that, in monocots, the fibrous roots develop from the base of the stem after the radicle goes absent. And since the roots here do not develop from the radicle but the base of the stem, they are called adventitious roots.
So with this information, I have the doubts:
- Are all fibrous roots adventitious?
- If all fibrous roots are adventitious, then are all adventitious roots always fibrous?
- Are all monocots fibrous rooted?
