Question

Options
angiosperms
gymnosperms
spore
bryophyta
thallophyta
zygote
Solution
In pteridophytes, asexual reproduction occurs by spore formation and sexual reproduction occurs by zygote formation.
Explanation:
Plants from this group have well-developed roots, stems and leaves and separate tissues for the conduction of food and water. But, they do not bear flowers and fruits. They reproduce with the help of spores formed along the back or posterior surface of their leaves. Examples are ferns like Nephrolepis, Marsilea, Pteris, Adiantum, Equisetum, Selaginella, Lycopodium, etc. These plants reproduce asexually by spore formation and sexually by zygote formation. They have a well-developed conducting system.
