The document discusses the classification and structures of plants. It describes the main types of plants as flowering plants, non-flowering plants, herbs, shrubs, trees, creepers and climbers. It then explains the root system and shoot system of plants, describing the main root, lateral roots, and parts of the shoot system including the stem, leaves, flowers and fruits. It provides examples and functions of different plant structures and how some structures are modified.

upright and spread out on the ground
Watermelon Strawberry

11. Plants different from Herbs, Shrubs and Trees
Climbers Plants with weak stems that cannot stand
and climb up with the help of support

12. PLANT SYSTEM
Root System
Underground part of the plant
which includes main root and
branched roots.
Shoot System
The part above the ground which
includes stem, leaves, buds,
flowers and fruits.

13. Root System
The underground part of the
plant.
Functions:
• It absorbs water and
minerals present in soil.
• It anchors the plant and
provides physical support.
• It binds the soil particles
together preventing soil
erosion.

14. Types of Root System
Lateral root

15. Roots are modified to store food
Carrot Radish Turnip

16. Roots are modified to give extra support
Prop Roots of Banyan Tree Prop Roots of Maize plant

17. Shoot System
The part above the ground.
It includes:
• Stem
• Leaf
• Fruit
• Flower
• Bud
• Node
• Internode

18. The Stem
The main body or stalk of a plant
that supports other parts.
Functions:
• Keeps plant upright.
• Bears branches, leaves, flowers
and fruits.
• Transports water, minerals and
food to all other parts.

19. Types of leaf venation
Parallel Venation in plants with
fibrous root
Reticulate Venation in plants with tap
root

20. Stems are modified to store food
Sugarcane Ginger
Potatoes

21. Stems are modified to give support
Stem Tendril

22. Stems are modified to make food

23. The Leaf
The thin and green
portion of plant.
Functions:
• Prepares food for
plant.
• Stomata in a leaf
releases water from
plant.

24. Stem Tendril
Leaves are modified to give support

25. Leaves are modified into spines
Spines

26. Flowers
The most attractive
part of the flowering
plant.
Male part: Stamen
Female Part: Carpel
Pedicel

27. Pedicel
Pollination in Flowers
