5. STRUCTURE OF A SEED

6. GERMINATION
The process of a seed growing into a
seedling is called germination.

7. Conditions required for germination are
presence of air , light , warmth and
optimum amount of water.

8. SEED DISPERSAL
The process of scattering of
seeds away from the parent
plant is called seed dispersal.

9. Agents of seed dispersal
• Dispersal by wind
• Dispersal by water
• Dispersal by animals
• Dispersal by explosion (not in the
book)

10. Dispersal by wind

11. Dispersal by water

13. Dispersal by animals

15. Dispersal by explosion

17. • Production of new plants from other
parts of a plant like stem ,roots, leaf
etc. of a plant is called vegetative
reproduction.
• New plants can grow from specific part
of the plant .such parts of the plant are
called as vegetative parts.
VEGETATIVE REPRODUCTION

18. Vegetative reproduction from stems

21. • Reproduction by bulbs

22. Reproduction by roots

24. Vegetative reproduction by leaves

25. Vegetative reproduction by spores
