Thank you for your feedback. I have put everything possible in the PPT so that anyone can learn without even listening to the audio. That's the reason I have read many of the lines directly. since it itself is the explanation and the concept is very basic.

  1. REPRODUCTION IN PLANTS BY NIKHIL PURANIK


  2. ABOUT MIE MY NAME IS NIKHIL PURANIK PURSUING B.E IN MECHANICAL ENGINEERING FROM RNSIT -LIVE IN BENGALURU PROFILE :https://unacademy.com/user/nikhilrpuranik


  3. TOPICS COVERED MODES OF REPRODUCTION ASEXUAL REPRODUCTION SEXUAL REPRODUCTION -FERTILIZATION FRUIT AND SEED FORMATION SEED DISPERSAL


  4. MODES OF REPRODUCTION Roots,stem and leaves are the vegetative parts of the plant The flowers are the reproductive parts of the plants and they may have either male, female or both reproductive parts. Plants produce their offspring in 2 ways. They are Asexual reproduction Sexual reproduction In asexual reproduction plants can give rise to new plants without seeds In sexual reproduction, new plants are obtained from seeds.


  5. ASEXUAL REPRODUCTION VEGETATIVE PROPOGATION - New plants are produced from the vegetative parts of the plants such as roots, stems, leaves and buds Developing bud ain of buds New bud Yeast cell BUDDING- The single celled organisms develop bulb like-O-0- projections called buds, which grow and get detached from the parent cell to form a new cell. FRAGMENTATION - An alga breaks up into two or more fragments or pieces, which then grow into new individuals. Sporangiunm Spores SPORE FORMATION- Spores are released into the air and they travel long distances by floating. Under favourable conditions, a le spore develops and germinates into a new plant


  6. SEXUAL REPRODUCTION The stamens are the male reproductive part and the pistil is the female reproductive part Stigma Pollens Stigma anther to the stigma of a flower is called Pollination. Anther If the pollen lands on the stigma of the same flower it is called self-pollination. When the pollen of a flower lands on the stigma ef polination of another flower of the same plant, or that of a different plant of the same kind, it is called cross- pollination. (b) Cross-pollination


  7. FERTILIZATION Pollen grain (germinating -The cell which results after fusion of the gametes is called a zygote. Pollen tube Zygote formation The process of fusion of male and female gametes (to form a zygote) is called Fertilisation. The zygote develops into an embryo Ovum


  8. FRUITS AND SEED FORMATION 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. Some fruits are fleshy and juicy such as mango, apple and orange. Some fruits are hard like almonds and walnuts


  9. SEED DISPERSAL Seeds and fruits of plants are carried away by wind, water and animals. Light seeds of grasses or hairy seeds of aak (Madar)_and hairy fruit of sunflower get blown off with the wind to far away places. Some seeds are dispersed by water. Example is coconut. Some seeds are dispersed by animals, Examples are Xanthium and Urena Some seeds are dispersed when the fruits burst with sudden jerks and the seeds are scattered far from the parent plant. Examples are castor and balsam.
