plants parts and structures

1. Plants and their parts

2. Part=Structure

3. Roots

4. Roots functions

5. 1)They (hold) anchor the plant to the
soil.

6. This is the anchor that keeps the
ship in its place

7. 2-They carry water and
nutrients to all parts of the plants.

8. Nutrients
substances that help living things
grow and stay
healthy .

9. 3) Some plants store food
in them.
Example: carrots

10. Roots types

11. 1) Taproot

12. Beet

13. Radish

14. Turnip

15. Carrot

16. Sweet potato

17. 2)Fibrous root

18. Cactus

19. Wheat

20. Taproot 0r fibrous
root?

21. So, now you can classify the plants
according to their root types

22. Stem

23. Stem functions

24. 1- It holds the plant up (supports the plant) and
enables the leaves to reach sunlight.

25. 2-It carries water, nutrients and food
throughout the whole plant.

26. Water is carried in the stem through
special openings
called (vessels or tubes)

27. Stem types

28. 1) Flexible green stem
It is found in small plants
Example:
Tulip Stem

29. 2) Stiff woody stem(trunk)
It is found in larger plants and trees
Example:
Tree trunks

30. Leaves

31. Leaves have different sizes and
shapes

32. Leaves functions

33. 1)It is the major part in the plant where it
makes its own food.

34. 2)It contains chlorophyll (chloroplast) that:
a)Gives the plant its green colour.
b)Helps the plant absorb sunlight.

35. Photosynthesis

36. Photo = light

37. People take in O2 and give out CO2

38. Plants use carbon dioxide to make
their food

39. (photosynthesis)
CO2+water+ sunlight food(sugar)+oxygen
nutrient chlorophyll

40. Plant takes in:
1- Water and nutrient from the soil.
2-Sunlight soaks the leaves which get
energy from the sunlight and trap it in
the chlorophyll(chloroplast).
3-Carbon dioxide enters small holes in
the underside part of the leaves.

41. Plant gives off:
1- Oxygen which we use to
breathe.
2-Sugar which is the plant food,
which gives it the energy needed
to grow.

42. 2. Sunlight
in
Oxygen out
1. Carbon dioxide in
3. Water
and
nutrients in
Food out

43. Food=sugar(glucose)

44. Remember
A green plant breathes all the time, day and
night.
A green plant photosynthesizes only in the
presence of sunlight.

45. How plants are different?
• They have different shapes and sizes

46. How are plants alike?
• 1- Have the same parts

47. • 2-Make their own food

48. • 3-They all have green parts

49. • 4- Grow in the ground

50. • 5- Can’t move like the animals
