The document discusses reproduction in plants. It describes the different methods of reproduction including seeds, stem cuttings, layering, spores, and roots. It explains the process of germination and parts of a seed like the seed coat, scar, and cotyledons. Seeds are categorized as monocotyledonous or dicotyledonous. Dispersal of seeds by wind, water, animals, and explosion is also outlined. The document concludes by discussing agriculture, crops, obtaining high crop yields, and protecting crops.

4. REPRODUCTION
Process by which new plants are grown from the
parent plant.
E.g. from mango seeds, mango trees are grown.
There are different methods used by plants for
reproduction-

5.  1. with the help of seeds.
 2 with the help of stem cuttings- e.g. rose

6.  3 reproduction from stem-e.g. ginger, potato

7. By layering . E.g.
jasmine plant

8.  4 Reproduction from leaves-

9.  5 reproduction from spores- e.g. ferns and
mushrooms.

10. 6. Reproduction by roots- e.g. sweet potato

11. Germination of seeds-
The growth of a baby plant or a seedling from seed is
called germination.

12. Parts of a seed-
1. Seed coat
2. Scar
3. Seed leaves or cotyledons
4. Baby plant

13. Depending on no. of cotyledons seeds are of two
types-
1. Monocotyledonous seed- e.g. rice, wheat, maize
2. Dicotyledonous seed- pea, bean, mango

14. Dispersal of seeds-
The process of spreading seeds to different places is
called dispersal of seeds.
Agents of dispersal-
1. wind- such seeds have wing or hair like structures.
E.g. madar

15. 2. Dispersal by water-
Such seeds easily float on water.eg. Coconut
3. Dispersal by animals- such seeds have hooks or
spines to stick with the body of animals.
4. Dispersal by explosion –
Such seeds disperse by explosion of fruits. Eg. poppy

16. Agriculture- growing of crops on large scale for food or
other purpose.
Crops- plants of a particular kind grown in a particular
region
How to get high- yield from crops-
1. Prepare the soil properly.
2. Use healthy and ripe seeds for sowing.
3. Add manure and fertilisers
4. Irrigate the soil well.
How are crops protected-
1. Use of insecticides and pesticides
2. Use of fungicides
3. Grazing animals can be kept away by proper
fencing.
4. Store the grains in water-proof , insect-proof,
airtight containers.
