Photosynthesis Concepts and Processes

The video explains how plants obtain food through photosynthesis, a process involving chlorophyll, sunlight, carbon dioxide, and water. It details the steps of photosynthesis, including the role of stomata and chloroplasts, and highlights the importance of additional nutrients like nitrogen for plant growth.

What is the primary function of photosynthesis in green plants?

• To convert sunlight into chemical energy

• To release carbon dioxide

• To absorb oxygen from the atmosphere

• To produce chlorophyll

Which pigment is essential for the process of photosynthesis?

• Carotene

• Xanthophyll

• Anthocyanin

• Chlorophyll

What role do stomata play in photosynthesis?

• They store carbohydrates

• They allow carbon dioxide to enter the leaves

• They transport water

• They absorb sunlight

In the photosynthesis reaction, what is the main product formed?

• Carbon dioxide

• Water

• Oxygen

• Carbohydrates

Where does photosynthesis primarily occur within the plant?

• In the flowers

• In the stem

• In the chloroplasts

• In the roots

Why are only green plants capable of photosynthesis?

• They absorb more water

• They grow in sunlight

• They have larger leaves

• They have chloroplasts

Which of the following is NOT a raw material for photosynthesis?

• Nitrogen

• Sunlight

• Carbon dioxide

• Water

What additional nutrients do plants require from the soil for growth?

• Oxygen and hydrogen

• Chlorophyll and sunlight

• Nitrogen, iron, phosphorus, and magnesium

• Carbon dioxide and water
