Question 4. What may be the possible advantage accruing out of the presence of antheridia and archegonia on the underside of a fern prothallus?
- They are protected from the direct rays of the sun.
- Capillary water accumulates on the underside of the prothallus between its lower surface and the soil surface. Sex organs projecting in this water can be readily fertilized by the ciliated sperms which are chemotactically attracted by the archegonia.
- The sex organs are protected from wind.
- Nutrients manufactured by the green prothallus can
readily seep downwards to the sex organs due to the action of gravity.
Answer: 2. Capillary water accumulates on the underside of the prothallus between its lower surface and the soil surface. Sex organs projecting in this water can be readily fertilized by the ciliated sperms which are chemotactically attracted by the archegonia.

- Gametophyte is dominant

- Sporophyte is total parasite
- Gametophyte is a total parasite.
