Plz. explain reproduction in FERN class 7
Answers
Most ferns reproduce through the alternation of generations, alternating successive generations of sexual and asexual forms. The second form of asexual reproduction occurs by spores. These form on the undersides of the leaves in clusters of spore cases called sporangia, or sori (singular, sorus).
Answer:
In sexual reproduction, new plants are obtained from seeds. The flowers are the reproductive parts of a plant. The stamens are the male reproductive part and the pistil is the female reproductive part. A pistil consists of stigma, style and ovary. The ovary contains one or more ovules. The transfer of pollen from the anther to the stigma of a flower is called pollination. The female gamete or the egg is formed in an ovule. In sexual reproduction a male and a female gamete fuse to form a zygote. The process of fusion of male and female gametes is called fertilisation. The zygote develops into an embryo. After fertilisation, the ovary grows into a fruit and other parts of the flower fall off. The fruit is the ripened ovary. The seeds develop from the ovules. The seed contains an embryo enclosed in a protective seed coat .Seeds and fruits of plants are carried away by wind, water and animals and reproduced again on the grounds.
