3. Making food from sunlight

4. Learning Objectives
At the end of the lesson students should be able
to :
• Describe the process of photosynthesis
• List the products of photosynthesis

5. HOW do plants make their own food?
How???
photosynthesis
the leaf glucose
Light energy
water oxygen
chlorophyll
carbon dioxide

6. Atomic Shuffle

7. Evidence that light is needed for photosynthesis
The leaf on the left is attached to a plant in light. The leaf on the right
has been tested for starch. The blue-black colour shows that starch
has been produced only where light shone on the leaf
Testing a leaf for starch

8. The leaf structure
The structures in a leaf are arranged so that carbon dioxide and water flow into the
leaf and glucose and oxygen can leave easily

9. Use of Food
Glucose : As a supply of energy
1
to make fats and oils (in seed)
Made into sucrose
2 - to be made into starch
- to be converted into cellulose
3 To make proteins
- glucose combined with nitrates
4 To make chlorophyll
- Glucose combined with magnesium

10. Integration & Islamization (I2)
Who governs the Plant?
Plants are organisms without any traces of
consciousness and reason such as decision-making
or free will.
But as you can see from the information provided this
far, the processes carried out by plants do require
considerable consciousness and reason.
Indeed, plants succeed in performing activities that
human beings cannot replicate with their conscious
knowledge and advanced technology, and in spaces
of time as brief as a millionth of a second. So to whom
does this intelligence—which human beings come
nowhere near approaching—belong?

11. Since the day they were first created, plants
have been behaving in the manner inspired
in them by Allah, with His infinite knowledge
and intelligence.
Each of the plants’ cell, is told how to behave at
every moment. This is revealed in a verse from
the Qur’an:
It is Allah Who created the seven heavens and of the
Earth the same number, the Command descending
down through all of them, so that you might know
that Allah has power over all things and that
Allah encompasses all things in His knowledge.
(Surat at-Talaq:12)

12. Whenever Allah wills a thing to come
about, it is enough for Him just to say,
"Be!"
As we are told in verses of the Qur’an:
His command when He desires a thing is
just to say to it, “Be!” and it is. (Surah Ya
Sin: 82)

13. Questions
Plants make their own food using ________
energy, carbon dioxide from the air and
______ from the soil. The process is called
________ . Leaves look ________ because
they contain chlorophyll. The __________
traps light energy. Most chlorophyll is in the
_______ cells near the top of the surface.

14. Questions
1 The roots of green plants take up nitrates from the soil.
What are the nitrates used to make?
A Fat
B Glucose
C Protein
D Starch
8 Why is sunlight is necessary for photosynthesis?
A It is a catalyst
B It is a source of energy
C It provides nutrients
D It provides oxygen
