(c) Berdasarkan rajah di atas, nyatakan tiga perbezaan antara proses X dengan proses Y. TP2
Based on the diagram above, state three differences between process X and process Y.

Proses X / Process X Proses Y / Process Y

(i) Berlaku di kloroplas / Occurs in chloroplasts Berlaku di mitokondria / Occurs in mitochondria

(ii) Dilakukan oleh tumbuhan Dilakukan oleh haiwan dan tumbuhan
Carried out by plants Carried out by animals and plants

(iii) Menggunakan air dan gas Q bagi Menggunakan glukosa dan gas P
menghasilkan glukosa dan gas P bagi menghasilkan air dan gas Q

Uses water and gas Q to produce glucose Uses glucose and gas P to produce
and gas P water and gas Q
(d)
Proses X dan proses Y saling bersandaran antara satu sama lain. / Process X and process Y are interdependent.

Jelaskan pernyataan di atas. TP4 KBAT Menganalisis
Explain the above statement.
Semasa proses Y , tumbuhan dan haiwan menyerap gas P dan membebaskan gas
Q . Gas Q digunakan oleh tumbuhan untuk menjalankan proses X . Gas P

yang dibebaskan semasa proses X digunakan semasa proses Y .

Y P Q Q
During process , plants and animals absorb gas and release gas . Gas is used by plants to carry
X P X Y
out process . Gas released during process is used during process .

5. Jalankan projek STEM di bawah. SP 2.2.2 TP4 KBAT Menganalisis
Carry out the STEM project below.
Project-Based Learning
Projek
Pr ojek
Objektif aktiviti: Berkomunikasi mengenai kesan bahan pencemar udara terhadap kadar fotosintesis.
Activity objective: Communicate about the effect of air pollutants on the photosynthesis rate.
Pernyataan masalah: Peningkatan kawasan perindustrian dan perumahan telah menyebabkan
pembebasan bahan pencemar udara seperti habuk, debu dan jelaga ke persekitaran. Hal ini menyebabkan
daun-daun tumbuhan diselaputi dengan habuk dan debu. Sejauh manakah kesan ini mempengaruhi
kadar fotosintesis?
Problem statement: Increase of industrial and residential areas have led to the release of air pollutants such as dust and soot into
the environment. This causes the leaves of plants to be covered with dust and soot. How far does this affect the rate of photosynthesis?
Pencarian fakta: Mencari maklumat bagaimana bahan pencemar udara mempengaruhi kadar fotosintesis.
Fact finding: Find information on how air pollutants affect the photosynthesis rate.
Konsep yang diaplikasikan: Menentukan berlakunya fotosintesis atau tidak melalui ujian kanji
Concept applied: Determining whether photosynthesis occur or not through the iodine test
Pelan tindakan: Mengenal pasti bahan dan radas yang diperlukan dengan mengambil kira kos.
Action plan: Identify materials and apparatus required by taking into account the cost.
Penyelesaian: Mengukur kadar fotosintesis di kawasan perindustrian dan di kawasan berhutan.
Solution: Measure the rate of photosynthesis in an industrial area and in a wooded area.
Pembentangan: Keputusan aktiviti dibentangkan dalam bentuk grafik.
Presentation: The results of the activity are presented in the graphic form.

Kriteria Kejayaan: ............................................................................................ .
Saya berjaya
• berkomunikasi mengenai respirasi sel • membezakan antara proses respirasi sel dan fotosintesis
• berkomunikasi mengenai proses fotosintesis • menerangkan perkaitan proses respirasi sel dan fotosintesis
