This document describes different parts of plants including leaves, stems, roots, and bark. It discusses describing leaves based on shape, edges, and position on the stem. Leaf position can be alternate, opposite, or whorled. Stems can be straight, climbing, or trailing. Bark texture can be soft, hard, rough, smooth, or bumpy. Roots can be tap roots or fibrous roots. The document provides examples and pictures. It concludes with designing an imaginary plant by deciding its features like stem, leaves, roots, fruit, and any special properties.

1. Describing Leaves
Week 3 Lesson 5 + 6

2. Let’s start with a look at
some interesting leaves!
Talk with your partner about
the pictures that you see.

8. •There are different ways to describe leaves.
•We will look at the differences between three pairs of
leaves.

9. The Lotus leaf is
round.
The corn leaf is
long and thin.

10. The Persimmon
leaf is smooth
and oval.
The cherry leaf is
serrated and
oval.

11. Serrated means
the edge of the
leaf has many
small, sharp
points.

12. This is an oval.
An Oval is a kind
of shape like a
circle, square or
triangle.

13. Maple
One leaf
Wisteria
Many leaves

14. •There are different ways to describe the position of
leaves on a stem.
•Position means- where the leaf is on the stem.
•We will look at three words to describe the position of
leaves on a stem.

15. Alternate:
One leaf grows from
each node on the
stem.
node
stem

16. Opposite:
Two leaves grows
from each node on
the stem.
node
stem

17. Whorled:
More than two
leaves grow from
each node on the
stem.
node
stem

18. Look at the leaves and
describe the leaf position!

19. Whorled

20. Opposite

21. Whorled

22. Alternate

23. Opposite

24. Alternate

27. Types of Stems
• There are different types of plant stems.

28. Straight Stem
• The Balsam plant has a straight stem.
• Straight stems support themselves.

29. Climbing Stem
• The Morning Glory has a climbing stem.
• Climbing stems wrap around other things to
support themselves.

30. Trailing Stems
• Strawberries have trailing stems.
• Trailing stems grow along the ground.

31. Types of Bark
• There are different types of bark.
• Bark is like the skin of a tree.
• Bark can be described using color and texture.

32. Texture
•Texture is the way something
feels.
•Texture Words:
▫Soft
▫Hard
▫Rough
▫Smooth
▫Bumpy

33. Soft

34. Hard

35. Rough

36. Smooth

37. Bumpy

38. Pine Tree Bark
• What does this look like?
• What do you think this feels like?

39. Keyaki Tree Bark
• What does this look like?
• What do you think this feels like?

40. Ginko Tree Bark
• What does this look like?
• What do you think this feels like?

41. Types of Roots
• Roots anchor a plant in the soil.
• Roots absorb water and transport it to the plant.
• Roots absorb nutrients and transport them to the
plant.
• Some roots store food.

42. Tap Root
• The first root produced from a seed is called the
radicle. In many dicot plants this root grows very
large and becomes the main root of the plant. It is
called a tap root. Many smaller roots, called
secondary roots, may grow from the tap root.

43. Tap Root

Secondary
roots

44. Fibrous Roots
In monocot plants, the radicle is
replaced by many roots of more less
equal size. These roots spread out
over a large area like a net.

45. Fibrous Roots
Look like a net.

46. • Some examples of fibrous roots are in the
garlic and scallion plants.
Garlic Scallion

47. Let’s design our own flowers.
• You need to decide some of its features.
▫ What kind of stem does it have? (Straight, Climbing or
Trailing?)
▫ How does it leaves grow? (Whorled, Alternate or
Opposite)
▫ Does it have any thorns on its stem?
▫ What kind of roots does it have? (Tap Root or Fibrous
Root)
▫ What does its leave look like?
▫ What kind of fruit does it have? What’s its fruit’s name?
▫ Draw its flower, what color is it?
▫ Does it have any special features like poisonous leaves?
▫ Where does your plant grow?
▫ If it’s a tree, what does the bark look like?

53. Plant Name : Adaidil
Fruit Name: Moccaberry
How do the leaves grow? Whorled
Describes the leaves: The leaves long and thin.
What type of stem does it have? It has a straight stem.
What type of roots does it have? It has fibrous roots.
Does your plant have any special features? If you eat the leaves of Adaidil you will have
amazing energy. You can go two days without sleeping.
