During the science class, Shanza and Kashif were discussing how plants grow. Shanza asked Kashif, "Where do plants get the energy needed for photosynthesis?"

• Nutrients in the soil

• The sun

• Chlorophyll

• Pollination by bees

Answer explanation

Plants get the energy for photosynthesis primarily from the sun. This process uses sunlight to convert carbon dioxide and water into glucose and oxygen, making the sun the essential energy source.

Shanza and Kashif are observing the leaves of a plant in their school garden. They notice that the leaves have a certain color due to chlorophyll. What is the color of chlorophyll?

• Green

• Blue

• Red

• Purple

Answer explanation

Chlorophyll is the pigment responsible for the green color in plants. It plays a crucial role in photosynthesis, allowing plants to absorb light energy. Therefore, the correct answer is green.

Pika pika! Kashif and Shanza are learning about plant cells in biology class. Which organelle in the plant cell is responsible for carrying out photosynthesis, pika?

• Chloroplasts

• Mitochondria

Answer explanation

The chloroplast is the organelle in plant cells responsible for photosynthesis, converting sunlight into energy. Mitochondria are involved in cellular respiration, not photosynthesis.

Pikachu and Shanza are studying plants in biology class. They are learning about a pigment in chloroplasts that performs photosynthesis. What is the name of this pigment, pika?

• Photosynthesis

• Chlorophyll

• ADP

• Electron Transport

Answer explanation

The pigment responsible for photosynthesis in chloroplasts is called chlorophyll. It captures light energy, which is essential for the process, making 'Chlorophyll' the correct answer.

Pika pika! During a biology experiment, Shanaza and Kashif are learning about the process of photosynthesis. Pika! What is the role of NADPH and ATP, pika?

• Pika! They absorb light

• Pika! They drive the light-dependent reactions

• Pika! They are pigments that reflect light

• Pika! They are short-term energy carriers

Answer explanation

NADPH and ATP are crucial in photosynthesis as they serve as short-term energy carriers, providing the energy and reducing power needed for the light-independent reactions, rather than absorbing light or reflecting it.

What is the capital of France?

• Berlin

• Madrid

• Paris

• Rome

Answer explanation

The capital of France is Paris, which is well-known as a major European city and cultural center. The other options, Berlin, Madrid, and Rome, are capitals of Germany, Spain, and Italy, respectively.

كاشف وشانزا يتعلمان عن عملية التمثيل الضوئي في صف الأحياء. إنهما فضوليان لمعرفة أين تحدث التفاعلات المظلمة، والمعروفة أيضًا بدورة كالفن، في البلاستيدات الخضراء. هل يمكنك مساعدتهما في العثور على الموقع الصحيح؟

• 
• اللمعة

• السدى

Answer explanation

The dark reactions, or Calvin cycle, occur in the stroma of the chloroplast. This is where carbon fixation takes place, utilizing ATP and NADPH produced in the light reactions.
