This document provides information about reproduction in plants. It discusses two main types of reproduction: asexual reproduction, which produces new plants without seeds, including vegetative propagation, budding, spore formation and fragmentation. Sexual reproduction involves the formation of seeds and includes the flower structure with stamen and pistil parts and the pollination process of transferring pollen grains. Seed dispersal is also covered, where seeds are carried from one place to another by various agents.

Reproduction in plants

3. Do you know what is Reproduction?
 The production of new organisms from their
parents is called reproduction.

5. Asexual Reproduction
• The type of reproduction in which new plants
arise without the formation of seeds
Vegetative propagation
Budding
Spore formation
Fragmentation

6. Vegetative propagation
The type of reproduction in which new plants arise from
vegetative parts of the plant is called vegetative propagation.

7. Budding
• The reproduction which occurs through the
formation of buds is called budding.
• Bud – The small bulb like projection coming out
from cell is called bud.

8. • The reproduction through the formation of
spores is called spore formation.
Spore formation

9. Fragmentation
The type of reproduction in which a cell
breakes up into two or more fragments.

10. The type of reproduction in which new
plants arise with the formation of seeds.
In this type of
reproduction, the
reproductive parts of a
plants i.e, flowers are

14. Types of flower
• Unisexual – Consist either stamen or pistil but
not both.
E.g. Corn, papaya & cucumber.
• Bisexual – Consist both stamen and pistil.
E.g. Mustard and rose.

15. The process of transfer of pollen grains
from stamen of a flower to pistil of the
same or different flower is called
pollination.
It is of two types as :-
a. Self Pollination
b. Cross Pollination
POLLINATION

19. 1. A same kind of plant grows in different places. It
is due to the process of seed dispersal.
2. The process of carrying of seeds from one place to
another is called seed dispersal.
SEED DISPERSAL

20. Can you guess by the help of which agents
the seed dispersal can take place.
