What are plants g4

1. What are plants?

2. What can you see in this picture?
It’s a family

3. Do you know that plants have family too?
- Plants have green leaves, stems, roots & flowers.

4. - Each & every part “member” in the plant has
its own function “job” which is very important
for the plant’s growth & survival.
(As each family member has a job to do
everyday; father goes to work, mother cooks
food, children go to school & study)

5. -Flowers have bright colors
that attract insects & birds
that drink the nectar.
- They make the seeds (inside
the fruits).
{They act like magnets as their
bright colors attract birds to drink
the nectar}
(1) Flowers

6. (2) Stems
- Stems take water & nutrients
from the roots to all the plant
parts.
- Stems hold the plants upright.
(A tree’s stem is called: Trunk)
{They act like pipes that carry
water to our homes as they carry
water to all plant parts}

7. (3) Roots
- Roots absorb “take” the water
& nutrients from the soil & give
them to the stem.
- Roots fix the plants in the soil.
{They act like a sponge that takes
in water from the soil, they also
act like an anchor that fix the boat
in the water}

8. (4) Leaves
- Leaves make the food for the
plant through a process called:
“Photosynthesis process”
{They act like the chef who cooks
food, as they are responsible for
making plant’s food}

9. - Every day you eat 3 meals:
“Breakfast in the morning”
“Lunch in the afternoon”
“Dinner At night”
- Plants also make 1 meal everyday
which is called: Photosynthesis
What is photosynthesis process?

10. Photosynthesis process
- It is the process in which the plants “leaves”
use sunlight, carbon dioxide from the air &
water & nutrients from the soil to make their
food.

11. In photosynthesis process:
+ ++
{Plants use carbon dioxide, sunlight , water & nutrients
to make photosynthesis then, oxygen & food are
released
+ Nutrients
Sugar

12. Now, let’s take a closer look at the
leaf

13. The structure of the leaf
Cuticle
Upper epidermis
Chloroplast
Stomata
Lower epidermis

14. (1) Cuticle:
• It is the waxy layer that coats the surface of
the leaf to protect the leaf from losing too
much water.
{It’s like a cover “coat” for the leaf that keeps the
leaf moist & protect it from becoming dry on a
very sunny day}

15. (2) Upper epidermis:
• It is the outer layer of the leaf that protect it
from damage.
{It’s like our skin that protect us from any damage,
plants have an outer layer “epidermis” that protect
it from any damage}

16. (3) Chloroplast:
• It gives the leaf its green color & it contains
chlorophyll that absorb sunlight in photosynthesis
process “makes food for plants”.
{It’s like the food factory of the plant}

17. (4) Stomata:
• It opens & closes letting carbon dioxide in &
oxygen out during photosynthesis.
{It act like our mouth “open & close to help us to
breath in oxygen & breath out carbon dioxide”}

18. Do you think that all plants look the
same like each others?
• Of course not, plants are so different from
each others.
• So let’s classify “divide” the plants according
to:

19. (1) Structure
A- Plants with leaves, stems & roots:
Example:
Trees

20. B- Plants with no leaves, stems or roots:
Example:
Mosses Worts

21. (2) Types of roots
A- Plants with tap roots: “Looks like a cone”
Example:
Beet root Carrot Radish

22. A- Plants with fibrous roots: “Looks like hairs”
Example:
Grass Cactus

23. (3) Types of stems
A- Plants with woody stems: “hard”
Example:
Trees Shrubs

24. A- Plants with soft stems:
Example:
Tulips Flowers

25. (4) Seeds
A- Seed plants:
- They produce new plants from seeds.
Example:
Apple trees Violet trees

26. B- Seedless plants:
- They produce new plants from spores.
“not from seeds”
(When spores are released & fall in the soil, then
they grow into new plants)
Example:
Horsetails Mosses Ferns

27. (5) Edible or Not
A- We eat the roots of:
Carrots Beet roots

28. B- We eat the stem of:
Celery Sugar cane Asparagus

29. C- We eat the leaves of:
Spinach Lettuce

30. D- We eat the flowers of:
Cauliflower Broccoli

31. E- We eat the seeds of:
Rice Beans Corn

32. - Some plants are not edible, but we use them:
1) As medicine
2) For making furniture

33. 3) For clothing
4) As fuel “Like gasoline”
