Read the following statements and choose the correct option: 1. The gametophytes bear male and female sex organs called antheridia and archegonia, respectively 2. Water is not required for transfer of antherozoids from antheridia. 3. In Pteridophytes, most of the plants are heterosporus. 4. The female gametophytes in these plants are retained on the parent sporophytes for variable periods

Step-by-step solution

The gametophytes bear male and female sex organs called antheridia and archegonia, respectively. Water is required for transfer of antherozoids released from the antherozoids. In majority of the Pteridophytes all the spores are of similar kinds, such plants are called homosporus. The female gametophytes in these plants are retained on the parent sporophytes for variable periods
