PLANTS:
NUTRITION AND REPRODUCTION

2. NUTRITION
As you know, plants need to grow:
- Water
- Minerals
- Carbon dioxide
- Sunlight

3. NUTRITION
Water + minerals are absorved in the
ROOTS
They create the RAW SAP
This raw sap goes from the ROOTS to the
LEAVES by the WOODY VESSELS

4. NUTRITION
Then, the plant absorbs the carbon
dioxide and the sunlight in the LEAVES
They create the ELABORATED SAP
The elaborated sap goes from the LEAVES
to the REST OF THE PLANT by the
LIBERIAN VESSELS

5. PHOTOSYNTHESIS
• It is the process in which the plant creates
their food in the leaves

6. REPRODUCTION OF THE PLANT
A plant can have two kinds of reproduction:
- Sexual reproduction
- With flowers: by seed
- Without flowers: by spores
- Asexual reproduction: with a fragment

7. SEXUAL REPRODUCTION
WITH FLOWER
Pollination can be:
- With the wind
- With the insects

8. SEXUAL REPRODUCTION
WITHOUT FLOWER

9. ASEXUAL REPRODUCTION
They reproduce by a fragment of the plant:
• Tubers
• Bulbs
• Rhizomes
• Stolons
• Cuttings

10. ASEXUAL REPRODUCTION
Tubers – potatoes

11. ASEXUAL REPRODUCTION
Bulbs – onions

12. ASEXUAL REPRODUCTION
Rizhomes - geraniums

13. ASEXUAL REPRODUCTION
Stolons - strawberries

14. ASEXUAL REPRODUCTION
Cuttings

15. QUESTIONS
• What are the components that go through the
woody vessels?
• What components are in the elaborated sap?
• In which two ways can a flower be pollinated?
• What are the five ways of asexual reproduction?

16. ACTIVITIES
1. Put the sentences in the correct order.
a) Photosynthesis takes place in the leaves. They change raw sap
into elaborated sap
b) The root absorb water and minerals to make raw sap
c) The elaborated sap takes food to other parts of the plant
d) The raw sap goes up the stem to the leaves
2. Make a mind map with the two kinds of reproduction

17. JOURNAL
Write two sentences about nutrition of the plant, and two
sentences about reproduction
