Which of the statements given below are correct about pteridophytes?
1 They are called vascular phanerogams
2 They produce seeds rather than spores
3 The gametophyte bears both male and female sex organs.
4 The sporangia produce spores by mitosis.
Explanation:
Pteridophytes are vascular cryptogams.They produce spores and exhibits an event precursor to seed habit. The gametophytes bear male and female sex organs called antheridia and archegonia, respectively. The sporangia produces spores by meiosis.
