In pteridophytes, to prevent self-fertilisation_
1 Plant becomes apomicitic
2 There is high degree of sterility
3 Antherozoids and eggs mature at different times
4 They can’t prevent self-fertilisation.
Explanation:
Pteridophytes exhibit dichogamy, the maturation of male and female sex organs at different times to prevent self fertilisation.

Which of the following plant group doesnot possesses vascular tissues xylem and phloem?
1 Bryophytes
2 Pteridophytes
3 Gymnosperms
4 Angiosperms
