PLANT LIFE

2. LEARNING OUTCOME
To understand plant life and its importance
To study in detail about root system
To learn shoot system of plant

3. LEARNING OBJECTIVE
State the importance of plants?

4. PLANT LIFE
Plants play very important role on earth.

5. PLANT LIFE
They provide food and oxygen to all other living
things.

6. PLANT LIFE
Plants are seen almost everywhere.

7. PLANT LIFE
They grow on land, on mountains, in deserts and
under sea.

8. PLANT LIFE
We know plants grow mostly from seeds when they
get enough water, sunlight and air.

9. LEARNING OUTCOME
To understand plant life and its importance
To study in detail about root system
To learn shoot system of plant

11. PLANT LIFE
THE ROOT SYSTEM

12. PLANT LIFE
Root is the underground part of the plants body and
grows towards the force of gravity.

13. PLANT LIFE
It fixes the plant within the soil and absorbs water
and mineral nutrients from the soil.

14. PLANT LIFE
It stores excess food.

15. PLANT LIFE

16. PLANT LIFE
TAP ROOTS

17. PLANT LIFE
It consists of one main long thick root growing
downwards from which many thinner roots develop.

18. PLANT LIFE
Taproot goes deep into the soil for searching for
water and minerals.

19. PLANT LIFE
Examples
Sugar beet or carrot, bean, tea, peepal etc. have tap
root.

20. PLANT LIFE
FIBROUS ROOTS

21. PLANT LIFE
In case of fibrous root there is no main root.

22. PLANT LIFE
It consists of a dense equal size roots that arise from
the stem.

23. PLANT LIFE
The roots grow downward and outward from the
stem, branching repeatedly to form a mass of fine
roots.

24. PLANT LIFE
Fibrous root does go very deep in the soil.

25. PLANT LIFE
Example
lilies, grasses, wheat, rice, palm etc. have fibrous
root.

26. PLANT LIFE
FUNCTION OF ROOTS

27. PLANT LIFE
Roots attach the plant body to the ground.

28. PLANT LIFE
It provides support to the plant and helps in holding
the plant firmly in the ground.

29. PLANT LIFE
Root hairs of the plant absorb water and mineral
from the soil and pass it to the stem.

30. PLANT LIFE
Some roots like carrot, radish etc. store food.

31. PLANT LIFE
Root bind the soil which otherwise may be blown
away by wind or washed away by water.

32. PLANT LIFE
Root prevents soil erosion.

33. LEARNING OUTCOME
To understand plant life and its importance
To study in detail about root system
To learn shoot system of plant

34. PLANT LIFE
THE SHOOT SYSTEM

35. PLANT LIFE
It is the aerial part of the plant body and enables
a plant to grow taller to gain access to energy-giving
light, and helps plant to prepare food.

36. PLANT LIFE
It is composed of erect stems on which are
attached leaves, flowers, branches and buds.

37. PLANT LIFE
Leaves are attached to the stem at regions called
nodes.

38. PLANT LIFE
STEM

39. PLANT LIFE
It supports the upper parts of plants.

40. PLANT LIFE
It carries the water and nutrients needed for
plants to grow from roots to leaves and food
produced by the leaves to other part of plants.

41. PLANT LIFE
Big trees like neem, mango, peepal etc. have
strong, thick and woody stem.

42. PLANT LIFE
Such stem is called trunk.

43. PLANT LIFE
Some plant have thick but soft stem, example
banana.

44. PLANT LIFE
Some plants have weak, soft and green stem as in
case of climbers and creepers, example watermelon,
money plant etc.

45. PLANT LIFE
FUNCTIONS OF STEM

46. PLANT LIFE
Stem provide support to the plant above the
ground.

47. PLANT LIFE
It bears branches, leaves, buds, flowers and fruits.

48. PLANT LIFE
Stem transport water and minerals from root to
other parts of the plants.

49. PLANT LIFE
It also transport food prepared by the leaves to
different part of the plants.

50. PLANT LIFE
Some underground stem stores food such as
sugarcane, potato, ginger etc.

51. PLANT LIFE
LEAVES

52. PLANT LIFE
Leaves are of different shapes and sizes.

53. PLANT LIFE
The outer surface of the leaf has a waxy coating
which protects the leaf.

54. PLANT LIFE
The flat surface of the leaf is called leaf blade or
lamina.

55. PLANT LIFE
It has veins running across within the leaf.

56. PLANT LIFE
Tiny opening on the surface of the leaves called
stomata helps in the exchange of gases.

57. PLANT LIFE
Stomata can be seen only under microscope.

58. PLANT LIFE
FUNCTION OF LEAVES

59. PLANT LIFE
These are the parts of the plant where food is
made by the process of photosynthesis.

60. PLANT LIFE
That’s why leaves are called the food making
factories of green plants.

61. PLANT LIFE
Chlorophyll (green pigment) present in the leaves
uses the energy in sunlight to turn water (H2O) and
carbon dioxide gas (CO2) into sugar and oxygen gas
(O2).

62. PLANT LIFE
Leaves gives out oxygen in the process of
photosynthesis.

63. PLANT LIFE
All living beings need oxygen to live.

64. PLANT LIFE
Some leaves store food in them such as mint,
cabbage etc.

65. PLANT LIFE
FLOWERS

66. PLANT LIFE
Flowers are the most attractive part of a plant.

67. PLANT LIFE
Each flower types have a different physical
structure, color and scent from those of other flower
type plants.

68. PLANT LIFE
Buds of the plants grows into flower and flower
finally becomes fruit enclosing the seed or seeds.

69. PLANT LIFE
Some fruits have one seed such as mango and
cherry.

70. PLANT LIFE
Some fruits have many seeds such as papaya and
watermelon.

71. PLANT LIFE
USES OF FLOWER

72. PLANT LIFE
Many flowers such as rose and jasmine are used
for making perfumes.

73. PLANT LIFE
Some flowers edible such as cauliflower, broccoli
and banana.

74. PLANT LIFE
Some spices are obtained from flower such as
saffron or kesar from crocus flower and cloves is
dried flower.

75. PLANT LIFE
Flowers are used for decoration on different
occasions and for preparing bouquets, garlands and
rangoli.

To study in detail about root system
To learn shoot system of plant
